New Description: [New Technology Field] This creation is about a backlight module and a liquid crystal display module that is related to a uniform brightness and chromaticity backlight module and card. ^Use this month first group [Prior Art] With the development of the electronics industry, flat panel displays have gradually replaced cathode ray official displays as the current mainstream of displays, and the technology of liquid crystal frequency dryers is more sophisticated and popular. Since the liquid crystal display panel of the liquid crystal display itself cannot emit light, a backlight module is provided under the liquid crystal display panel as a display light source of the liquid crystal display panel. In the light source of the backlight module, in addition to a cold cathode fluorescent lamp (CCFL), a light emitting diode (LED) is generally used, which has brightness. Still, low power consumption, long service life, and slight thermal problems. In the case of a light-emitting diode as a light source for a backlight module, first, a light-emitting diode is soldered to a circuit board by a surface mount technology (SMT) to form a light bar. Then, the light strip is pasted onto the frame of the backlight module. The light emitted by the polar body in the light-emitting strip enters the light guide plate through the light-incident surface of the light guide plate, and then passes through the light-emitting surface of the light guide plate to the outside of the light guide plate to form a surface light source required for the liquid crystal display. It is known in the production process of the light strip that the light emitting diode is soldered.
