Embodiment Construction

[0024] see figure 1 , figure 1 It is a three-dimensional exploded schematic view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 2 includes a first frame 21 , a liquid crystal panel 22 , a backlight module 23 and a second frame 29 . The backlight module 23 is adjacent to the liquid crystal panel 22 and provides backlight for the liquid crystal panel 22 . The first frame 21 is engaged with the second frame 29 to form a receiving space for receiving the liquid crystal panel 22 and the backlight module 23 . The first frame 21 defines a display window, and most of the liquid crystal panel 22 is disposed on the display window, and the user can watch the picture displayed on the liquid crystal panel 22 through the display window.

[0025] The first frame 21 is a two-stage structure, which includes a first portion 211 and a second portion 212 that are separated from each other and opposite to each other. The...

Abstract

The invention relates to a liquid crystal display device which comprises a first frame, a liquid crystal display panel, a backlight module and a second frame. The first frame and the second frame are fastened to from an accommodation space for accommodating the liquid crystal display panel and the backlight module. A display window is defined by the first frame to be used by users for watching pictures displayed by the liquid crystal display panel. The backlight module comprises a hollow plastic frame, a light guide plate and at least two point light sources. The light guide plate and the first frame are disposed on the inner side and the outer side of the plastic frame respectively. A passage is arranged in a position of the plastic frame, which right aligns to the light guide plate, to communicate the inner side and the outer side of the plastic frame. The at least two point light sources are fixed on the inner side surface of the first frame and stretch into the passage of the plastic frame. The point light sources are arranged on the first frame of the outermost side, so that the distance from the point light sources to the light guide plate is prolonged, light emitted by the point light sources is fully mixed before entering the light guide plate, and the light emitting uniformity of the liquid crystal display device is guaranteed.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] In recent years, liquid crystal display devices have gradually occupied the mainstream of display products and gradually replaced traditional cathode ray tube display devices due to the advantages of light and thin volume, small space occupation, and low radiation. A liquid crystal display device usually includes a side light source, such as a backlight module, to provide a plane light with sufficient brightness and uniformity for the liquid crystal panel. [0003] A liquid crystal display device in the prior art includes an upper iron frame, a liquid crystal panel, a backlight module and a lower iron frame. The upper iron frame and the lower iron frame are fastened together to form a receiving space for accommodating the liquid crystal panel and the backlight module arranged in layers. The backlight module includes a plastic frame for accommodating components suc...
