Description

display module

technical field

The utility model relates to the display field, in particular to a display module.

Background technique

Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, no radiation, etc., and has been widely used, such as mobile phones, personal digital assistants (PDA), digital cameras, computer screens or notebook computer screens wait.

Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. The structure of a traditional liquid crystal display panel consists of a color filter substrate (Color Filter), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) arranged between the two substrates. ), its working principle is to control the rotation of liquid crystal molecules in the liquid crystal layer by applying a driving voltage on two glass substrates, and refract the light from the backlight module to produce a picture. Since the liquid crystal display panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device. Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. The direct-lit backlight module is to install a light source such as a cathode fluorescent lamp (Cold Cathode Fluorescent Lamp, CCFL) or a light emitting diode (Light Emitting Diode, LED) behind the liquid crystal display panel to directly form a surface light source for the liquid crystal display panel. The side-type backlight module is to set the backlight LED light bar (Light bar) at the edge of the back panel behind the liquid crystal display panel, and the light emitted by the LED light bar is from the side of the light guide plate (Light Guide Plate, LGP) The light incident surface enters the light guide plate, is reflected and diffused, and exits from the light exit surface of the light guide plate, and then passes through the optical film group to form a surface light source for the liquid crystal display panel.

Please refer to FIG. 1 , which is a three-dimensional exploded schematic diagram of an existing liquid crystal display module, which includes: a backlight module 100 , a plastic frame 300 disposed on the backlight module, a liquid crystal display panel 500 disposed on the plastic frame 300 and a device. The front frame 700 on the liquid crystal display panel 500, the backlight module 100 provides a surface light source with uniform illumination for the liquid crystal display panel 500, the plastic frame 300 is used to carry the liquid crystal display panel 500, and the front frame 700 is used to The liquid crystal display panel 500 is fixed on the plastic frame 300 .

As display devices become thinner and lighter, the above-mentioned display module structures are increasingly unable to meet consumer needs, and a new thinner and lighter display module structure has become a demand.
