Abstract

The invention discloses a display device and a backlight module. The backlight module comprises a substrate, an ink layer and a plurality of light emitting units, wherein the substrate comprises a first end and a second end which are oppositely arranged; the ink layer is arranged on the substrate and comprises a plurality of hollow units which are gradually distributed from the first end to the second end; the at least two light emitting units are arranged on the ink layer in an array mode. The display device and the backlight module provided by the invention are used for improving the problemof uneven brightness display in the surface of the backlight module due to the fact that the brightness of the backlight module close to the power input side is higher than that of the backlight module far away from the power input side.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a backlight module. Background technique [0002] The backlight of the traditional low-end liquid crystal display turns on when the light is turned on, and turns off when the light is turned off. The brightness adjustment of the final picture depends on the light blocking of the liquid crystal display layer. However, due to the limitations of various actual processes, materials, etc., the contrast can reach up to 5000:1, and the visual effect of the picture displayed by this contrast is not good. Traditional mid-range LCDs can also achieve local Dimming products with tens to hundreds of partitions, which can better improve a certain contrast. However, because the number of partitions is limited by LED Pitch (light-emitting diode pitch), etc., the display effect is presented There are often halos, which affects the viewing quality. [0003] Therefore, Mini...
