Problems solved by technology

The light emitted by the light source 8 will enter the light guide plate 9, and the area of ​​part A is the visible area A of the display quality, but because the light emitted by the light source 8 into the light guide plate 9 will leak from the concave position 91 partially unevenly, a phenomenon occurs. Light leakage (light leakage), such as figure 1 As shown in B in the backlight device, the phenomenon of uneven

Abstract

The invention provides a backlight device of a display, wherein the backlight device mainly comprises at least one light source device, a casing, a light guide plate, a plurality of fixed structures and a plurality of light shielding elements. The casing comprises a bottom plate. The light guide plate is provided with an upper surface, a lower surface and a side surface, the edge of the light guide plate is provided with a plurality of openings and the lower surface thereof faces the casing and is arranged on the casing. The fixed structures are arranged on the bottom plate in a convex manner, corresponding to the openings of the light guide plate, and penetrate the openings of the light guide plate. The light shielding elements have a light penetration rate less than 50% and are arranged at the openings of the light guide plate.

Description

Technical field [0001] The present invention relates to a backlight device, in particular to a backlight device applied to a liquid crystal display in a flat panel display. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, flat panel displays (Flat Panel Display) have flourished. Among them, liquid crystal displays (Liquid Crystal Display / LCD) are based on their low-voltage operation, no radiation scattering, light weight, and small size. Advantages, it has gradually replaced traditional cathode ray tube displays and has become the mainstream of display products in recent years. The liquid crystal display mainly includes a liquid crystal display panel (Liquid Crystal Display Panel) and a backlight device (backlight module), wherein the backlight device is used to provide the surface light source required by the liquid crystal display panel, and the light guide plate (Light Guide Plate) is used...
