Problems solved by technology

The method of manufacturing a color flat-panel display by stacking three layers of display units results in poor resolution and, as shown in the figure, the brightness of blue light is lower than that of red light
The array arrangement of the display units does not need to use different mirrors, and more importantly, it can provide excellent resolution and uniform brightness among various colors. However, due to the different lengths of the chambers, the three display units must be separated. Manufacture, for example, when manufacturing the display unit 302, it is necessary to use photoresist to cover the areas where the display units 304 and 306 are to be formed. The complex process itself is costly, and what is more serious is that the yield cannot be improved due to the complex process.

Embodiment 1

[0028] Please refer to Figure 5 , Figure 5 It is a schematic cross-sectional view of an optical interference type display unit according to a preferred embodiment of the present invention. An optical interference type display unit 500 can be used as a color-changing pixel unit, and includes at least a first electrode 502 and a second electrode 504, wherein the first electrode 502 and the second electrode 504 are arranged approximately in parallel. The first electrode 502 and a second electrode 504 are selected from a combination of narrowband mirrors, broadband mirrors, non-metallic mirrors, and metallic mirrors, or combinations thereof.

[0029] The first electrode 502 is a partially penetrating and partially reflective electrode, and is generally composed of a substrate 5021, an absorption layer 5022, and a dielectric layer 5023. When the incident light passes through the first electrode 502, part of the intensity of the incident light is absorbed by the absorption layer 5022....

Embodiment 2

[0034] Please refer to Figure 6 , Figure 6 It is a schematic cross-sectional view of an optical interference display unit array according to the second preferred embodiment of the present invention. An optical interference display unit array 600 has three parallel optical interference display units 602, 604, and 606, and the three optical interference display units 602, 604, and 606 can form a pixel. The structure of each light interference type display unit is similar to that disclosed in Embodiment 1, and the difference lies in the support. The light interference type display unit 602 is supported by the support arms 608 and 610, the light interference type display unit 604 is supported by the support arms 612 and 614, and the light interference type display unit 606 is supported by the support arms 616 and 618, wherein the support The two arms 608 and 610, 612 and 614, 616 and 618 have the same length and thickness, and have the same stress. After the thermal process, the dis...

Abstract

The light interference type display panel includes at least one first electrode and one second electrode supported by some supporting matter with at least one supporting arm. The second electrode is one deformable reflection electrode. The light beam incident to the first electrode is reflected via the first electrode owing to the light interference between the first electrode and the second electrode, and the frequency of the reflected light depends on the distance between the first electrode and the second electrode. The supporting arm may be bent upwards or downwards owing to stress, and this alters the distance between the first electrode and the second electrode and can obtain reflected light of different frequency.

Description

Technical field [0001] The present invention relates to an optical interference type display panel structure, in particular to an optical interference type display panel with a support arm. Background technique [0002] Due to its small size and light weight, flat-panel displays have great advantages in portable display devices and display markets for small space applications. In addition to liquid crystal displays (LCD), organic electro-luminescent displays (OLED), and plasma displays (Plasma Display Panel, PDP), today’s flat-panel displays use light interference The flat display mode has been proposed. [0003] Please refer to USP5835255, which discloses an Array of Modulation of visible light, which can be used as a flat panel display. See figure 1 , figure 1 It is a schematic cross-sectional view of a known display unit. Each light interference type display unit 100 includes two walls 102 and 104. The two walls 102 and 104 are supported by a support 106 to form a cavity 108...
