[Previous technology] In today's life, "Don't worry about love" Φ m # 5 it ^ 0 m is used in some video display technology devices. The liquid crystal display (LCD) is shore-based industrial electronics. It is also ready to be used together. ## It is one of the main technologies used in these display devices. / 、 The external light source is required. T9 ja / Portable Lei Zao μ 偌, 1 to display the image. But in these? The type of electronic a is usually battery-based. In consideration of power saving, how can the electric knife come to you? The gangster's use efficiency of light has become very important.-: There are many technologies to improve the efficiency of light irradiation applied to LCD ', U i: The technology is not only applied to portable electronic devices, but also widely used. Applied to image projection, it is mainly divided into DMD (Digital Mirror Device) projection and LCD projection. The projected image is finally presented to the audience through some media. The quality of the image seen by the audience is very different from the media. Big relationship. The screen is usually used as the projected medium, depending on the audience's environment and the projection theory used. 'This screen may be used for front projection (fr0nt projection) or internal projection (rea; r pr0jecti.) n). M274545 IV. Creative Instructions (2) More than half of the non-polarized light generated by the cold cathode ray tube will be absorbed when passing through the polarization conversion 'first polarizer of the layer', making the light irradiation efficiency very bad. The polarization conversion layer is used to separate the polarized light that can pass from the non-passable polarizer. For example, the first-A KK shows that the polarization conversion layer 10 can be composed of an upper polarizing plate 丨 2 and a lower polarizing plate 14. An upper polarizing plate 12 and a lower polarizing plate 14 are maintained between Preset space ... 6 Generally, the P wave and the S wave are included in the light wave, and the P wave is concentrated to the orthogonal direction by polarization conversion ^, and the S wave is filtered and removed. Then use the reflective Φ plate to convert the reflected light into usable polarized light. In addition, as shown in FIG. -B, the preset space 16 can be replaced by one or more layers of material stack 18 (stack) with different refractive indices, so that the polarization conversion layer becomes a retroreflecting plate. polarizer) to increase brightness. Therefore, if the light irradiation efficiency when the light is refracted into and out of the polarization conversion layer 10 can be improved, the overall light irradiation efficiency can be better. [New content] One of the purposes of this new type is to add a microlens system to the polarization conversion layer to improve the light irradiation efficiency. Another object of the present invention is to provide a light-transmitting material to expand the shape of the micro lens to cover the gap portion of the micro lens array, so as to improve the irradiation efficiency of the incident light in the gap portion of the micro lens array to the row.
