Abstract

We report an optimized blue phase liquid crystal (BPLC) mixture JC-BP08 for field-sequential-color (FSC) display applications. JC-BP08 exhibits several attractive features: 1) its fast average gray-to-gray response time enables FSC display, which in turn triples the resolution density and optical efficiency. 2) Its voltage holding ratio is >99.4% at 25°C and >93.2% at 60°C. 3) Its average dielectric constant ε’≈87 is still manageable by the bootstrapping driving to enable 240 Hz operation. 4) Using a triangular protrusion electrode structure, the transmittance can reach 74% at 15V, which enables single-TFT driving. 5) With two-domain structure, it offers indistinguishable gamma shift and wide viewing angle. We proposed a voltage charging model and found a linear relationship between the required charging time and ε’, which is validated by our experimental results.

1. Introduction

Polymer-stabilized blue phase liquid crystal (PS-BPLC) [1,2] exhibits several attractive features for display and photonic applications, such as submillisecond response time, no need for surface alignment, optically isotropic dark state, and insensitive to the cell gap if an in-plane switching (IPS) cell is employed [3]. However, after ~15 years of extensive efforts, BPLC still remains at the prototype stage [4,5]. The major hurdles are twofold: 1) high operation voltage (Vp) and 2) slow capacitor charging for active matrix addressing. High Vp dramatically increases the power consumption, while slow charging limits the device resolution and frame rate. To reduce Vp, two main approaches have been commonly practiced: protruded electrodes [6,7] and large Kerr constant BPLC materials [8–10]. To enhance Kerr constant, several BPLC materials with Δn>0.18 and Δε>100 have been developed [11,12]. The major concerns for such a huge Δε BPLC material are: 1) increased rotational viscosity (γ1), which leads to a slower response time (>1 ms), and 2) longer capacitor charging time when addressed by TFTs (thin film transistors); this problem magnifies as display resolution or frame rate increases. To overcome the slow charging issue, bootstrapping driving, i.e. pre-charging method has been developed [13,14]. If the average dielectric constant (ε’) is smaller than 100, then the charging issue can still be managed. But the dilemma stays: lower Δε leads to increased Vp. Therefore, a delicate balance between operation voltage, response time, and charging time has to be taken into consideration. An ideal BPLC should possess following properties: fast charging time for high resolution and high frame rate, high transmittance at 15 V for single-TFT driving, and submillisecond response time for field-sequential-color (FSC) displays [15]. FSC eliminates the need of color filters so that it triples the optical efficiency and resolution density. These features are highly desirable for the emerging wearable virtual reality and augmented reality display applications.

In this paper, we report a BPLC mixture, called JC-BP08, which is optimized for FSC displays. Its physical properties are listed as follows: ε’ ≈87 so that the TFT charging issue is still manageable, VHR >99.4% at 25°C once charged, and response time 0.83 ms at room temperature (RT). Using a protruded electrode structure, our simulation results indicate that we can obtain transmittance ~74% at 15 V using JC-BP08. This is an important step towards single TFT (per pixel) addressing.

2. Experimental results and discussion

2.1 Materials and measurement

In the past few years, three commercial BPLC mixtures have been well studied; they are PSBP-01 (JNC, Japan) [8,12,16], Merck BPLC [11], and HTG-135200 (HCCH, China) [17,18]. Among them, Merck’s mixture is only available to some specific customers. JNC’s PSBP-01 has a relatively large Kerr constant, which helps to lower the operation voltage. However, its decay time is around 1.6 ms, which is fast for conventional 120-Hz framerate operation, but not fast enough for FSC, which demands ≥240 Hz in order to mitigate color breakup. Finally, the HCCH’s mixture is for experimental studies only, not intended for active matrix display applications because of its relatively low voltage holding ratio (VHR≈80%) [18].

Here, we prepared a new BPLC mixture: JC-BP08 (from JNC). The compositions and UV curing conditions are described as follows: JC-BP08 precursor contains 84 wt. % nematic LC host, 4.8% chiral dopant, 10.8% monomers, and 0.4% photoinitiator. The dielectric anisotropy and birefringence of the LC host of JC-BP08 are ∆ε = 114 (at f = 1 kHz and 25°C) and ∆n = 0.161 (λ = 589 nm and 25°C), respectively. Before UV curing, the phase transition temperatures are: N* 53.0°C BP during heating and BP 50.8°C N* during cooling, where N* stands for chiral nematic phase. After UV curing at BP-I, the physical properties of polymer-stabilized JC-BP08 are: ε’ = 87 at f = 60 Hz and 25°C, clearing temperature TC = 75°C, and melting point Tmp < −20°C.

To characterize the electro-optic performance, we filled JC-BP08 into an IPS cell with no surface alignment layer. Because JC-BP01 has a similar ε’ value, we include it as benchmark for comparison. The IPS-8/12 cells we employed have ITO electrode width w = 8 μm, electrode gap g = 12 μm, and cell gap d = 7.3 μm. When heated to BP-I, the cells were cured under UV light (λ~365 nm, intensity 8 mW/cm2) for 15 min. For convenience, we call the two samples as PSBP-01 and PSBP-08. Our experiment was conducted at RT unless otherwise mentioned.

Figures 1(a) and 1(b) depict the measured voltage-dependent transmittance (VT) curves and temperature dependent decay time of PSBP-01 and PSBP-08, respectively. Here, the transmittance is normalized to that of two parallel polarizers. We also fit the experimental VT curves with the extended Kerr effect model, in which the induced birefringence ∆nind is related to the electric field E as [19]:

Δnind=Δns(1exp[(E/Es)2]),
where ∆ns stands for the saturated birefringence and Es for the saturation electric field. As Fig. 1(a) depicts, Eq. (1) fits the measured VT curves of PSBP-01 and PSBP-08 well by TechWiz (SANAYI System). Through fittings, we found ∆ns = 0.138 and Es = 6.0 V/μm for PSBP-08, and ∆ns = 0.135 and Es = 4.7 V/μm for PSBP-01. Based on these parameters, we obtained Kerr constant K = 6.1 nm/V2 for PSBP-08, and K = 9.7 nm/V2 for PSBP-01. Our Kerr constant of PSBP-01 is somewhat smaller than that reported in [8], because our measurement is at a higher temperature. As Figs. 1(a) and 1(b) depict, PSBP-01 shows a lower Vp than PSBP-08 because of its larger Kerr constant, but its response time is >2x slower than that of PSBP-08 at RT. This difference amplifies in the low temperature region. The difference between PSBP-01 and PSBP-08 mainly comes from the average elastic constant k, which contributes to Kerr constant K and response time τ by the following equations [2,20]:
KΔnΔεP2kλ(2π)2,
τγ1P2k(2π)2,
where Δn, Δε, P, and γ1 represent the birefringence, dielectric anisotropy, pitch length, and rotational viscosity of the BPLC composite, respectively, and λ is the wavelength. JC-BP01 has its advantage of large Kerr constant, so the low operation voltage makes it useful for general displays. However, submillisecond response time is essential for FSC displays in order to suppress color breakup [21,22]. To achieve a faster response time than JC-BP01, our JC-BP08 exhibits a larger k, which helps to shorten the response time (Eq. (3)) but its Kerr constant is somewhat compromised (Eq. (2)). The pitch length is also slightly adjusted from P = 412 nm for PSBP-01 to P = 376 nm for PSBP-08.

PSBP-08 is particularly attractive for FSC displays because of its sub-millisecond response time. Table 1 lists the measured gray-to-gray (GTG) response time (τ) of PSBP-08 at RT without overdrive and undershoot voltages. The averaged GTG rise time is 0.9 ms and decay time is 1.0 ms.

2.2 Wavelength and frequency effects of PSBP-08

For a given PSBP composite, ∆ns governs its optical response, e.g. transmittance, while Es determines its operation voltage. Both ∆ns and Es influence Kerr constant by [16]

K=Δns/(λEs2).
Equation (4) implies that to lower the operating voltage (i.e. larger Kerr constant), higher ∆ns, shorter wavelength and lower Es are preferred.

2.2.1 Wavelength effect

Figure 2 depicts the wavelength effect of PSBP-08. In Fig. 2(a), we fixed Es = 6.0 V/μm at f = 240 Hz and fitted the VT curves at the specified wavelengths. The obtained ∆ns values are plotted in Fig. 2(b). We further fitted the ∆ns dispersion with following equation [23]:

Δns=Gλ2λ*2λ2λ*2,
and obtained the proportionality constant G = 2.07 μm−2 and the mean resonance wavelength λ* = 239 nm. From Eq. (5), we find ∆ns = 0.146 at λ = 550 nm for PSBP-08.

2.2.2 Frequency effect

A higher TFT frame rate helps to mitigate color breakup, but the tradeoff is increased electronic power consumption. To balance these two effects, most LCD TVs are operated at 120 frames per second (frequency f = 60 Hz). For FSC displays, in order to reduce color breakup, the frame rate should be 240 Hz (f = 120 Hz) or higher. Figure 3(a) depicts the frequency dependent VT curves. As the frequency increases from 60 Hz to 2 kHz, Vp increases gradually. To fit each VT curve, we fixed ∆ns = 0.138 (for λ = 633 nm) and obtained different Es values. Based on the ∆ns and Es values, we calculated the Kerr constant as plotted in Fig. 3(b). Next, we fitted the experimental data with following extended Cole-Cole equation [16]:

K(f)=K+(KsK)1+(ffr)1αsin12απ1+2(ffr)1αsin12απ+(ffr)2(1α).
Through fittings, we find the static Kerr constant Ks = 6.5 nm/V2, high frequency Kerr constant K = 0, Debye relaxation frequency fr = 1.2 kHz, and α = 0.13. For comparison, fr = 1.3 kHz for PSBP-01 [16]. Since PSBP-08 has a similar ε’ to PSBP-01, their fr values are also comparable. As Fig. 3(b) depicts, Kerr constant decreases gradually as the frequency increases. At f = 120 Hz (frame rate 240 Hz), the Kerr constant slightly decreases to 6.1 nm/V2.

2.3 Charging issue for high dielectric constant BPLC materials

Fast capacitor charging time plays a key role for FSC and high-resolution display devices. In 2013, Haseba, et al. [12] used PSBP-06 to demonstrate that LC with a larger dielectric constant (ε’) needs a longer time to be fully charged. A higher ε’ LC implies to a larger capacitor, as a result, it requires a longer time to accumulate the electric charges. Similar to Kerr constant, the dielectric constant of BPLC declines as the driving frequency increases. A short (typically 20 μs) DC voltage from TFT contains some high frequency components. From Fig. 3(b), during such a short charging time, the corresponding ε’ value is very small. Since the following frame time is much longer than the charging time, the voltage-holding frequency is much lower than the charging frequency. At the beginning of open circuit, the working frequency drops quickly from the high charging frequency to the low voltage-holding frequency, thus ε’ and the capacitance increase instantly, resulting in a low charged-in voltage. Nematic LCs do not suffer such problem because their ε’ is small and ε’ is insensitive to the driving frequency as long as f<100 kHz.

To illustrate the slow charging time and low VHR issues of a BP LCD, let us assume the applied voltage is Vo = 10 V and charging time tc = 16 μs. Because the BPLC has a large capacitance, it requires much longer time to reach 10V. With such a short charging time, the charged-in voltage Vi is about 4.2 V, which is much lower than Vo, as Fig. 4(a) shows. After a holding time of th = 8.3 ms [240 frame/second], the held voltage decreases to Vh. Therefore, two parameters determine the electrical performance of a BP LCD: 1) charging time: it is related to ε’ and fr, which indicates how ε’ changes with frequency; 2) VHR defined as Vh/Vi: it represents how well the voltage is held in a given frame time. Our PSBP-08 has a moderate ε’, its charging time is about 250 μs, which is still more than 10x longer than that of a conventional nematic LC. But once charged, its VHR reaches 99.4% at 25°C and 93.2% at 60°C. The high VHR is because JC-BP08 consists of mainly fluorinated multi-ring compounds [17]. Fluorinated LCs exhibit a high resistivity, which leads to a large VHR [24], and have been widely used in TFT LCDs.

In principle, we should compare the charging issues of our PSBP-08 with PSBP-01 directly. However, there are no such data available for PSBP-01. Instead, we found the experimental data of PSBP-06 reported in [12]. Figure 4(b) shows the measured Vi/V0 of PSBP-06 (red dots) and our measured PSBP-08 (black triangles). PSBP-06 has a very large ε’ (~200), so its required charging time is about 1.5 ms. To understand the slow charging phenomenon, we propose following equations:

Vi/V0=1exp(tc/t0),
t0=bε'(f),
f=12tc,
where tc is the charging time (a variable), t0 is a characteristic charging time, which is linearly proportional to ε’ by a constant b, and f is the driving frequency ( = 0.5 × frame rate). First, we fit the red dots in Fig. 4(b) with Eqs. (7)-(9), as the red line shows, and obtain b = 1.704. The agreement between model and experiment is very good. Next, we use the same b value to fit our PSBP-08 data without any adjustable parameter. Results are shown by the black line. Again, the agreement is good, although we have only two data points. Therefore, our model is validated experimentally. As shown in Fig. 4(b), PSBP-06 has a huge ε’, which is desirable for lowering the operation voltage, but the required charging time is 1.5 ms. By contrast, PSBP-08 has a smaller ε’ so that its required charging time (~250 μs) is shortened by 6x, which is easier to be addressed by the pre-charging method [13,14].

3. Device simulation

Although we have overcome the charging issues, the high driving voltage is PSBP-08’s Achilles heel. Our target is to lower the operation voltage to 15V to enable single-TFT addressing, while keeping a reasonably high transmittance, say >70%. In this Section, we perform device simulation using PSBP-08 in some reported protrusion structures.

3.1 Protrusion electrode for low driving voltage

In 2009, Rao, et al. [6] proposed a protruded electrode structure for lowering the operation voltage. This approach is proven to be quite effective. Several groups have fabricated such structures [4,5,25], especially in 2015 AUO demonstrated such protrusion electrodes in a 10” BPLC prototype [5]. The peak transmittance is over 75%, but the operation voltage is 32 V so that two TFTs per pixel are required. High Vp increases the power consumption while two TFTs reduce the aperture ratio and optical efficiency.

For the protrusion structure, fabrication technique limits the best performance that can be achieved. As Fig. 5(a) depicts, to lower Vp, we could decrease the protrusion gap G to increase the electric field intensity between two protrusions, or increase protrusion height H for the incoming light to accumulate more phase retardation. Nevertheless, narrower G demands a smaller protrusion width L to keep high transmittance, since the area above the protrusion is a dead zone. Under such a condition, tall and thin protrusion is favored, but of course, they are more challenging to fabricate. Several other electrode structures have been proposed, but the fabrication is a limiting factor in practice [26–28]. In 2012, Yamamoto, et al. proposed and fabricated a triangular electrode structure (Fig. 5(a)) to improve contrast ratio [29,30], whose protrusion height is H = 2.14μm and length L = 1.32μm. A diamond-shape electrode structure is also proposed, which exhibits a promising performance [31].

3.2 Performance of PSBP-08 on protruded electrodes

Here, we study the performance of our PSBP-08 using the protruded triangular electrodes. In Fig. 5(a), a ridge protrusion is deposited on the bottom substrate, then ITO stripes are sputtered onto the ridge protrusion. Except for the protrusion gap G, the parameters used in our simulation are kept the same as those prototypes reported in [29,30], so that the fabrication processes should also be the same: H = 2.14 μm, L = 1.32 μm, cell gap d = 4 μm; the ITO tails beside the protrusion are for applying voltage. The black line in Fig. 5(b) shows the simulated VT curve using the experimental protrusion gap G = 2.68 μm. The peak transmittance is ~82% at 22V. To lower Vp to 15V, we reduce the protrusion gap to G = 1.5 μm, which is still comparable to the dimension of protrusion width L = 1.32 μm. As the red line shows in Fig. 5(b), we can achieve 74% transmittance at 15V. Thus, PSBP-08 is a promising candidate for practical applications.

For display applications, gamma shift is another important parameter. The well-known example is multi-domain vertical alignment for LCD TVs. In order to suppress gamma shift, 12 domains are often employed. As a result, the transmittance is greatly reduced because the domain walls block the light.

Here, we investigate the gamma shift of BP LCDs. It has been reported that a single-domain BPLC exhibits greyscale inversion, and to suppress grayscale inversion and widen viewing angle, two-domain structure and biaxial compensation film are needed [32]. We calculated the gray level (GL, G0-G255) from transmittance (T) by T = (GL/255)2.2. The gamma curves along the most severe gamma shift direction (φ = 230°) are plotted in Fig. 5(c). We find the off-axis image distortion index D(θ, φ) = 0.135. From previous studies [33,34], as long as D<0.2 the gamma shift is unnoticeable to the human eye. Therefore, for BP LCDs we only need two domains to achieve wide-view and distortion-free off-axis images. By merely using two domains, the effective transmittance should remain high. Moreover, since we are using IPS structure, which is insensitive to the cell gap, the BP LCD should work well for touch panels.

4. Conclusion

Our new PSBP-08 exhibits following outstanding features: 1) its submillisecond response time enables FSC operation, which in turn triples the resolution density and optical efficiency. 2) Its VHR is adequate to support FSC operation. 3) Its blue phase temperature range (from −20°C to 75°C) is adequate for indoor applications. 4) Its average dielectric constant is 87, which is still below the upper limit for bootstrapping driving. Thus, it can be operated at 240 Hz, provided that the high mobility oxide TFTs are employed. 5) Using the triangular electrode structure, PSBP-08 can achieve 74% transmittance at 15V, which enables single-TFT driving. 6) With two-domain structure, our BP LCD offers indistinguishable gamma shift and wide viewing angle. A linear relationship between charging time and ε’ is proposed and validated by experiment.
