Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention, and the drawings are only for the purpose of illustration, and are not drawn according to the original scale.

[0030] Such as Figure 1 to Figure 7 As shown, this embodiment provides a direct-lit liquid crystal display device, including a backplane 1, a middle frame 2, a front frame 3, a backlight module 4, and a display screen 5, wherein the backplane 1 is made by stamping and bending a thin metal plate , comprising a bottom plate 11 and side plates 12 inclined upwards from both ends of the bottom plate 11. Here, a trapezoidal spac...

Abstract

The invention discloses a direct type liquid-crystal display device and relates to the technical field of electronic and electrical products. The direct type liquid-crystal display device comprises a back plate, a middle frame, a front frame, a backlight module and a display screen, wherein the back plate comprises a base plate and side plates, the middle frame is installed on the side plates through fasteners and clamping tables, a supporting plate is further arranged on the middle frame, the backlight module is embedded between the supporting plate and the back plate, the front frame covers the outer side of the back plate and the outer side of the middle frame, and the display screen is embedded between the front frame and the supporting plate. A reinforcing plate is further fixed to the back plate, clamping hooks are arranged on the reinforcing plate, the backlight module comprises lamp strips, the lamp strips are provided with clamping holes, and the clamping hooks are matched with the clamping holes to fix the lamp strips on the reinforcing plate. The strength of the back plate is improved by arranging the reinforcing plate on the back plate, back plate damage during lamp strip installation is avoided, the size of the back plate is decreased, and the production cost is saved. In addition, the lamp strips and the reinforcing plate are connected through the clamping hooks and the clamping holes, mounting and dismounting are convenient, the assembly time is saved, and the lamp strip mounting and changing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic and electrical products, in particular to a direct-type liquid crystal display device. Background technique [0002] With the rapid development of electronic imaging technology, liquid crystal display devices have been widely used in various electronic and electrical products, such as liquid crystal displays, televisions, all-in-one computers, and communication equipment. Existing liquid crystal display devices are usually divided into two types: direct-type and side-type. The light-emitting elements of the direct-type are evenly distributed at the rear of the liquid crystal screen, while the light-emitting elements of the side-type are arranged around the liquid crystal screen and rely on light guide plates to refract images. Since the direct type is to uniformly arrange the LED crystal grains behind the liquid crystal panel as the light source, its backlight can evenly transmit the entire scr...
