Embodiment Construction

[0046] As far as LCOS panels are concerned, the current mainstream LCD mode is MTN-90 (mixed-mode twistnematic). The optical characteristics of the LCOS panel using this liquid crystal mode, such as contrast ratio, reflectivity and response time, have room for further improvement.

[0047] Therefore, in an exemplary embodiment of the present invention, the LCOS panel includes stacked compensation film layers, which can select different stacked compensation film layers according to the optical characteristics of the liquid crystal layer, so as to effectively improve the contrast and reflection of the reflective display panel. rate and shorten its optical response time.

[0048] Figure 1A It is a schematic diagram of a structure of a reflective display panel according to an embodiment of the present invention. Please refer to Figure 1A , in this embodiment, the reflective display panel 100 is, for example, an LCOS panel. The reflective display panel 100 includes an LCOS back...

Abstract

The invention relates to a structure of a reflecting display panel, which comprises a silicon substrate, a liquid crystal layer and a stack type compensation film layer. The liquid crystal layer is arranged above the silicon substrate and is provided with a first phase delay value, wherein the first phase delay value is within a first delay range. The stack type compensation film layer is arranged above the liquid crystal layer and is provided with a second phase delay value, wherein the second phase delay value is within a second delay range. According to an optical property of the liquid crystal layer, the stack type compensation film layer is selected, so that the contrast ratio of the reflecting display panel is improved.

Description

technical field [0001] The invention relates to a structure of a display panel, in particular to a structure of a reflective display panel. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display) has been vigorously developed. Among them, the liquid crystal display has gradually replaced it based on its advantages of low voltage operation, no radiation scattering, light weight and small size. Traditional cathode ray tube displays have become the mainstream of display products in recent years. For example, a reflective liquid crystal display using a liquid-crystal-on-silicon panel (hereinafter referred to as an LCOS panel) and the like. [0003] As far as the LCOS panel is concerned, it is mainly composed of a substrate made of a silicon wafer and an opposite substrate made of glass. LCOS panels use MOS transistors to replace thin film transistors use...
