Problems solved by technology

[0005] However, in the hollow backlight system 10, the use of the first light guide plate 11 and the second light guide plate 12 increases the cost and weight, and the light guide plate is generally made of transparent plastic, which is prone to deformation, yellowing and stress concentration. problems, thereby affecting the service life of the backlight system; and, the setting of the hollow light guide area 16 increases the thickness of the backlight system; in addition, for liquid crystal display panels with different sizes of light-emitting surfaces, it is necessary to use backlight systems 10 of different sizes. Therefore, the It is difficult for the backlight system 10 to be applied to liquid crystal display panels with light-emitting surfaces of different sizes

Abstract

This invention relates to one aphototropism system, which comprises diffusion board and light source module set; the light source module set comprises light source and base socket; the base socket comprises bottom board on one side of diffusion board and one side wall connected to bottom board; the side wall is between bottom board and diffusion board; the said light source is fixed on side wall inside with protruding part facing light source reflection surface to reflect the lights to the diffusion board.

Description

【Technical field】 [0001] The invention relates to a backlight system applied to a liquid crystal display device, in particular to a reflective backlight system. 【Background technique】 [0002] With the vigorous development of the liquid crystal display (Liquid Crystal Display, LCD) industry, the product application levels of various liquid crystal display panels continue to increase, and lighter and thinner products are constantly introduced. Since the liquid crystal display panel is a non-self-illuminating display panel, a backlight system must be used to perform the display function. [0003] The backlight system is divided into side-light type and direct-light type according to the location of the light source. The light source of the edge-lit backlight system is arranged on the side of the backlight assembly. It generally uses a light guide plate to convert the light source into a surface light source and then utilizes it. The light uniformity is better, but the brightn...
