Embodiment Construction
[0035] As mentioned in the background technology section, in the prior art, the backlight module formed by Mini LED is prone to starry sky phenomenon during the display process.
[0036] The reason that inventor finds above-mentioned phenomenon occurs is:
[0037] See figure 1 , figure 1 A schematic diagram of the top view structure of a display device provided for the prior art; in the display device 100, there will be a certain distance between adjacent LED chips 02, for example, there is a first gap between two adjacent LED chips 02 in the X direction. The spacing W, and the second spacing L between two adjacent LED chips 02 in the Y direction. See figure 2 , figure 2 for along figure 1 The cross-sectional schematic diagram of the backlight module of the line AA' in the middle; wherein, the LED backlight module includes a PCB board 01, a number of LED chips 02 are arranged on the PCB board 01, a fluorescent film 03 is arranged on the LED chip 02, and the light emitti...
