Abstract

The invention discloses a lamp panel, a backlight module and a display device. The lamp panel includes several panels; each panel is provided with several light-emitting chips; the same amount. The technical effect of the present invention is that the lamp panel can be evenly partitioned, so that the luminous effect of the light-emitting chips in each partition is the same, that is, the uniformity of light emission of the lamp panel can be improved, and the uniformity of light emission of the display panel can be further improved.

Description

technical field [0001] The invention relates to the display field, in particular to a lamp panel, a backlight module and a display device. Background technique [0002] In recent years, with the development of full-screen liquid crystal display technology, miniLED and microLED technology can control the light of LCM by zones due to their direct light-emitting characteristics, which has a natural advantage in improving the contrast performance of LCM. [0003] In order to achieve high contrast, the light-emitting chips 300 (chips) of the miniLED are partitioned, and each partition 200 independently controls the light-emitting state of the light-emitting chips 300 of each partition 200, and the light-emitting state of the light-emitting chips 300 in the same partition 200 is identical. [0004] When the overall size of the mini LED light board is large (such as 8 inches or more), the usual practice in the industry is to divide the light board into several pieces, and then use...
