Definitions
- the present invention relates to the field of liquid crystal display, and in particular to a backlight module. Background technique
- Liquid crystal display has many advantages such as thin body, power saving, and no radiation, and has been widely used.
- Most of the liquid crystal display devices on the market are backlight type liquid crystal displays, which include a liquid crystal display panel and a backlight module.
- the working principle of the liquid crystal display panel is to place liquid crystal molecules in two parallel glass. There are many vertical and horizontal small wires between the two glass plates.
- the liquid crystal molecules are controlled to change direction by energization or not, and the light of the backlight module is reflected. Produce a picture. Since the liquid crystal display panel itself does not emit light, it is necessary to display the image normally by the light source provided by the backlight module. Therefore, the backlight module becomes one of the key components of the liquid crystal display device.
- the backlight module is divided into a side-lit backlight module and a direct-lit backlight module according to different incident positions of the backlight.
- a backlight such as a CCFL (Cold Cathode Fluorescent Lamp) or an LED (Light Emitting Diode) is disposed behind the liquid crystal display panel, and a surface light source is directly formed and supplied to the liquid crystal display panel.
- the side-lit backlight module has a backlight, such as an LED backlight, disposed on the edge of the back panel behind the liquid crystal display panel, and the light emitted by the LED backlight enters the light guide plate from the light incident surface on the side of the light guide plate. After being reflected and diffused, it is emitted from the light-emitting surface of the light guide plate to form a surface light source for being supplied to the liquid crystal display panel.
- the existing backlight module mainly comprises: a back plate, a light guide plate, a backlight, and an optical film, and the back plate is generally made of the same material, and the material used is aluminum plate, iron plate or plastic. If the entire backing plate is made of iron plate, it is necessary to add heat dissipating components, which will lead to an increase in cost; if the entire backing plate is made of aluminum plate, no additional heat dissipating components are required, although the aluminum heat conduction effect is better than the iron plate. Good, but only part of the entire backplane plays a role in heat dissipation, and the other part does not play a role of heat dissipation but support, which is not conducive to cost control and support of the liquid crystal module.
- the installation method of the existing backlight is mainly fixed on the back plate by means of thermal conductive tape or screws, and the backlight is fixed on the back plate through the thermal conductive tape. Since the thermal resistance of the thermal conductive tape is large, the thermal conductivity is only 0.9 ⁇ 6W. /K*m, the thermal conductivity of aluminum can reach 137W/K*m. Although the thermal conductivity of the backlight and backplane is very high, the thermal conductivity of the thermal conductive tape is very low, so the heat generated by the backlight cannot be quickly guided. go. And the backlight is fixed to the back plate by screws, without screws Where the lock is attached, there is an air layer between the backlight and the back plate. Due to the poor thermal conductivity of the air, the surface contact thermal resistance increases, so the overall heat dissipation effect is still poor. Summary of the invention
