Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] As mentioned in the background, the backlight module is divided into a side-type backlight module and a direct-type backlight module according to the incident position of the light source. The side-type backlight module is to install the light-emitting device at the edge of the light guide plate on the back of the liquid crystal panel. The light emitted by the light-emitting device enters the light guide plate from the side of the light guide plate, and ...

Abstract

The invention discloses a direct-type backlight module and a display device. The direct-type backlight module includes a plurality of main lamp beads arranged on the same surface of a substrate, and the gap between any adjacent main lamp beads corresponding to the substrate is a light-transmitting area. And an auxiliary lamp bead is provided on the side of the substrate away from the main lamp bead. During the working process of the direct-lit backlight module, the light emitted by the auxiliary lamp beads can pass through the light-transmitting area to compensate the brightness of the gap between two adjacent main lamp beads and improve the mixing of two adjacent main lamp beads in the gap area. The problem of insufficient light can further improve the problem of poor uniformity of the outgoing surface light source of the direct-type backlight module, and can also improve the brightness of the surface light source to ensure high display effect of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, more specifically, to a direct-lit backlight module and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, no radiation, etc., and has been widely used, such as: mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen etc. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal panel is composed of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin FilmTransistorArray Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the t...
