Embodiment 1

[0041] The structure of double-sided IPS blue phase liquid crystal display of the present invention is (as figure 1 ):

[0042] The double-sided IPS blue-phase liquid crystal display of the present invention comprises (from bottom to top order): polarizer 1, lower glass substrate 2, strip-shaped ITO electrodes 3 and 4 on the inner surface of the lower glass substrate, lower insulating layer 5, sealing frame glue 6. Spacer 7, blue phase liquid crystal layer 8, upper insulating layer 9, strip-shaped ITO electrodes 10 and 11 on the substantially inner surface of the upper glass, upper glass substrate 12, and analyzer 13.

[0043] In the double-sided IPS blue-phase liquid crystal display of the present invention, the strip-shaped ITO electrodes 10 and 11 on the inner surface of the upper glass substrate are required to be located above the center of the gap between two adjacent strip-shaped ITO electrodes 3 and 4 on the inner surface of the lower glass substrate. The strip-shaped...

Abstract

The invention relates to a double-sided IPS blue phase liquid crystal display which comprises a polarizer, an analyzer and a double-sided IPS blue phase liquid crystal box, wherein the internal surfaces of an upper glass substrate and a lower glass substrate of the double-sided IPS blue phase liquid crystal box are provided with striped ITO electrodes, the electrode width and the electrode gap of the striped ITO electrodes on the internal surface of the upper glass substrate are the same with those of the striped ITO electrodes on the internal surface of the lower glass substrate, and each striped ITO electrode on the internal surface of the upper glass substrate is positioned above the central position of the gap between two adjacent striped ITO electrodes on the internal surface of the lower glass substrate. Compared with the traditional IPS blue phase liquid crystal display with lower drive voltage, the DS-IPS electrode structure increases the transmittance by more than 25% (>85%). Compared with the traditional IPS blue phase liquid crystal display with higher transmittance, the DS-IPS electrode structure decreases the drive voltage by more than 25%.

Description

technical field [0001] The present invention relates to a high transmittance and low voltage blue phase liquid crystal display mode, specifically a double-sided IPS blue phase liquid crystal display (Double-side In-Plane Switching Blue Phase Liquid Crystal Display), referred to as DS-IPSBP- LCD. Background technique [0002] The traditional IPS blue phase liquid crystal display (In-Plane Switching Blue Phase LCD), referred to as (IPS BP-LCD), is to use the horizontal electric field generated by the strip-shaped ITO electrode gap on the inner surface of the lower glass substrate to make the blue phase liquid crystal molecules from all directions. The isotropic phase is transformed into an anisotropic phase, and bright-state liquid crystal displays are realized due to the birefringence effect. It has the characteristics of fast response, wide viewing angle and high contrast, and can be widely used in large-screen LCD monitors such as desktop monitors and LCD TVs. [0003] Th...
