Display panel

Abstract

The invention provides a display panel, which comprises a first substrate and a second substrate facing each other a display medium arranged between the first substrate and the second substrate in a sealed manner, and a pixel array. The pixel array is disposed on the first surface of the first substrate, the first surface facing the second substrate. The display panel also comprises multiple long protruding layers. The multiple long protruding layers are arranged to extend on the first surface in order, each long protruding layer is provided with multiple protruding structures, each protruding structure has a top surface, each top surface faces the second substrate, each top surface is shaped like a rhombus, and the two diagonals of each rhombus are not equal. The display panel further comprises driving electrodes. The driving electrodes cover the multiple long protruding layers. The long protruding layers with the rhombus-shaped top surfaces are adopted and the driving electrodes cover the long protruding layers, so that light that passes through the first substrate to enter the display panel has a small deflection angle. In this way, light leaks in a dark state are minimized, and the display contrast is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a blue phase liquid crystal display device. Background technique [0002] The blue phase liquid crystal display has the characteristics of response time below milliseconds, wide viewing angle and high contrast ratio, and does not require an alignment layer in the production process, nor does it need to impose strict restrictions on the thickness of the liquid crystal layer, the production cost is low, and the manufacturing process is simpler. , which is considered to have the most potential to become the next generation of liquid crystal displays. The traditional blue-phase liquid crystal display is driven in the form of driving electrodes of an in-plane switching (In-Plane Switching, IPS) liquid crystal display. It is necessary to make a storage capacitor to obtain a high voltage retention rate. Only a small amount of light passes through, and the driving voltage is relatively...

Problems solved by technology

However, for the method of improving the performance of blue-phase liquid crystal materials, such as the preparation of blue-phase liquid crystal materials with a large Cole constant, the process of synthesizing blue-phase liquid crystal materials is complicated, so the research and development costs are very expensive; In terms of the driving method, due to the limited penetration depth of the lateral electric field generated by the parallel electrodes in the driving method of the IPS structure, a higher driving voltage is still required; for the method of using bumps and raised electrode structures For this reason, the driving voltage can be lower, but there is also the problem of light leakage in the dark state, which causes the contrast of the display to decrease.
