Description

LCD Monitor

technical field

The utility model relates to liquid crystal display technology, in particular to a liquid crystal display.

Background technique

Liquid Crystal Display (LCD for short) is favored by people because of its thin and light appearance, small size, low low-voltage power consumption, and no radiation. Currently, LCDs are widely used in mobile phones, personal digital assistant displays, or large Size computer screens and TVs, etc., can provide a more perfect display effect. A liquid crystal display is usually composed of a liquid crystal display panel and a backlight module, wherein the backlight module is composed of a plastic frame, an optical film, a light guide plate, etc. in the plastic frame. Panel, glue frame and optical film on the other side. However, during bonding, the flexible circuit board of the liquid crystal display panel will be bent to the bottom of the liquid crystal display, and the bending position of the flexible circuit board will generate internal stress, which will pull up the optical film, which will easily cause defects such as light leakage. phenomenon, thereby affecting the display quality. Moreover, if the light-shielding double-sided tape is directly arranged on the liquid crystal display panel and the optical film, it will cause uneven light emission, thereby affecting the display quality.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

1 to 4 schematically show a liquid crystal display according to the present invention.

According to one aspect of the present invention, a liquid crystal display is provided, including a liquid crystal display panel 1, a backlight module 2 and a casing, the backlight module 2 includes a plastic frame 21, and the plastic frame 21 is provided with a size matching the size of the liquid crystal display panel 1 The installation groove 22 of the rubber frame 21 is provided with protrusions 23 on four sides, and the shape of the protrusions 23 is an inverted right triangle. The liquid crystal display panel 1 is disposed in the installation groove 22 , and the ends of both sides of the installation groove 22 are provided with fixing areas 24 . The side of the liquid crystal display panel 1 is provided with a fixing member 11 matching the fixing area 24 . Through the fixing member 11 and the fixing area 24 , the horizontal displacement of the liquid crystal display panel 1 due to vibration after installation can be prevented, thereby protecting the liquid crystal display panel 1 .

The shell includes a bottom shell 3 and an upper shell 4. The bottom shell 3 is provided with a first fixing hole 31 matched with the protrusion 23.
