BACKLIGHT-TYPE MINI LED CHIP AND FABRICATION METHOD THEREFOR

Disclosed are a backlight-type Mini LED chip and a fabrication method therefor. According to a preset arrangement of Mini LED chips, a grating in a shape corresponding to the preset arrangement is etched on a backlight reflective layer of each chip, such that the light shape of the Mini LED chips is...

description Disclosed are a backlight-type Mini LED chip and a fabrication method therefor. According to a preset arrangement of Mini LED chips, a grating in a shape corresponding to the preset arrangement is etched on a backlight reflective layer of each chip, such that the light shape of the Mini LED chips is controlled, the chips can be divided into more regions, which is equivalent to increasing the arrangement density of the chips, the visual resolution experience is improved, and the resolution perceived by human eyes is increased, thus improving the display effect of the chips; and the width of the grating can be adjusted to change the ratio of vertical emergent light and lateral emergent light of the chip, so as to adjust the angle and intensity of emergent light of the chip, such that the control effect and display effect of the Mini LED chips are further improved.
