Problems solved by technology

However, due to problems such as warping, unevenness, breakage, light truncation, and black border cutting at the splicing position, dark lines are generated at the splicing position, which makes the color tone of the splicing position inconsistent with the normal light-emitting area, which affects the light output quality of the display.

Abstract

The invention relates to a light-emitting module, a backlight module and a display device. The light-emitting module comprises at least two light-emitting panels which are spliced with each other, and further comprises a display area corresponding to each light-emitting panel; and a light supplementing area which corresponds to the area where at least two light-emitting panels are spliced with each other, wherein the light supplementing area comprises a light supplementing element. According to the light-emitting module, dark lines can be prevented from being generated at the splicing positions of the spliced light-emitting panels, and the light-emitting quality of the light-emitting module is improved.

Description

Technical field[0001]The present application relates to the field of display, and in particular, to a light-emitting module, a backlight module, and a display device.Background technique[0002]With the rapid development of display technology, the viewing of larger screens requires more and more popular, such as the large-size display in the Command Monitoring Center, the business center, the high-end meeting, the private cinema, etc. Has a broad application prospect. The splicing screen technique has emerged, and the so-called splicing screen technology refers to a large display screen that splices multiple vertical arrangements.[0003]The large-sized display screen includes, for example, a light Emitting Diode display, which is integrated with a plurality of small-sized LED light-emitting panels. However, due to the problem of warpage, uneven, break, light truncation, cut black edge, etc., resulting in a dark line in the splicing position, so that the hue of the splicing position is ...
