As far as displays are concerned, cathode ray tubes (CRT) have been dominating the display market in recent years due to their excellent display quality and economy. However, for the environment where individuals operate most terminals / display devices on the table, or from the perspective of environmental protection, if the trend of energy saving is predicted, there are still many problems with cathode ray tubes due to space utilization and energy consumption, and Demands for lightness, thinness, shortness, smallness, and low power consumption cannot effectively provide a solution. Therefore, liquid crystal displays (LCDs) with superior characteristics such as high daylight quality, increased space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. The liquid crystal display Is (LCD) is mainly composed of a liquid crystal panel (liquid crystal panel) and a backlight module (Black light module (B / L)). It is worth noting that, since the liquid crystal injected into the liquid crystal panel does not emit light by itself, it is necessary to light the liquid crystal panel through a surface light source provided by the backlight module to achieve the display effect of the liquid crystal display.

No additional adhesive tape is required between the optical module and the plastic frame, which can save assembly man-hours and reduce material costs. Although the present invention has been disclosed in the preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and retouching without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection shall be determined by the scope of the attached patent application.
