Problems solved by technology

[0003] However, if figure 1 and figure 2 As shown, because the LED light source has a certain light-emitting angle, the light emitted by the LID light source cannot completely irradiate the corner formed by the light bar and the bottom of the liquid crystal display device, so that the corners in the liquid crystal display device are at the edge of the light-emitting angle of the LED light source or emit light. Beyond the angle, dark corners are formed, which affects people's browsing and processing of the content at the corners of the LCD screen

Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] With the development of display technology, liquid crystal displays (Liquid-crystal Display: LCD) have gradually replaced traditional anode ray tube displays due to their superior characteristics such as light and thin body, low power consumption and no radiation. A general liquid crystal display is mainly composed of a liquid crystal display p...

Abstract

The invention discloses a display device. The display device comprises a display panel, a frame, and a backlight module; a backboard is arranged in the frame; the backlight module comprises a light source used for casting light on the display panel; the light source comprises a light bar on which a plurality of light emitting units are distributed; the light bar is fixed to the backboard and oppositely arranged on the backboard, so that part of the light emitted by the light emitting units, close to both ends of the backboard, of the light bar deviates to corners of the display panel. According to the display device, the problem that the corners of the display panel become dark corners can be avoided, the display effect is improved, and display and observation are better facilitated.

Description

technical field [0001] The present application relates to the display field, in particular to a display device. Background technique [0002] Liquid crystal display devices (including liquid crystal televisions, liquid crystal displays, etc.) generally use LEDs as light sources. In the manufacturing process of the liquid crystal display device, a plurality of LED light sources are positioned on a straight circuit board to form a light bar after being punched, and then the light bar is fixed on the side of the heat-dissipating aluminum extrusion or the back plate. After the circuit board is powered on, the LED light source on the light bar is driven to light up the LCD screen, so that people can view the text or pictures displayed on the LCD screen. [0003] However, if figure 1 and figure 2 As shown, because the LED light source has a certain light emitting angle, the light emitted by the LID light source cannot completely irradiate the corner formed by the light bar and...
