It can be understood that the light diffusing plate can also be provided with no scattering particles, and the light-incident surface 5341 can be roughened (r0Gghening), which can also achieve the purpose of light mixing. [0028] Optical correction element 536 is a microstructured array located on the light exit side of the total reflection lens. The microstructure array includes a plurality of microstructures, each of which can be __Product No. A0101 Page 10 / Total 21 Page 1013196777-0 1377527 1101 〇 5 Kai 23 曰倐 Zheng Fan page is a columnar right triangle, The height Η is less than 30 μm (/im), and the spacing between adjacent two microstructures is less than 4 μm. The light emitted from the light exit surface 5343 of the light mixing element 534 is deflected downward by the deflection of the microstructure array. 'This prevents the light from coming out and becoming useless light. [0029] In addition, it should be noted that the light mixing element and the optical correction element in the foregoing embodiments may be an integrally formed structure, or may be a separately disposed structure. The light mixing elements of the plurality of pixel units of the light emitting diode display device in the foregoing embodiments may be integrated and arranged in a matrix, for example, by using an injection molding method or separately from each other. Similarly, the optical correcting elements of the plurality of pixel units of the LED display device can be integrated together in a row or column arrangement, or can be separated from each other as shown in FIG. The plurality of light-emitting diodes in each pixel unit are not limited to a combination of red, green, and blue primary color light-emitting diodes, and may be a combination of other primary color light-emitting diodes known to those skilled in the art.
