Problems solved by technology

Such a large amount of deformation will bring the following problems. First, the liquid crystal display panel on the light guide plate in the backlight module will be deformed, cracked or peeled off; the optical film group will be seriously deformed and form waving (brightness and darkness changes)
If the upward arching of the light guide plate is restricted by other fixing methods, the light guide plate will form multiple wavy warps with low arch heights, which will cause permanent deformation of the light guide plate, and it will not be able to return to a straight state after cooling, resulting in Brightness and darkness changes on the light panel

Embodiment Construction

[0023] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0024] see image 3 , the present invention provides a side-type backlight module, which is a backlight module with double-sided light input, which includes: a backplane 2, two backlight sources 4 that are relatively arranged in the backplane 2, and a The light guide plate 6 inside the board 2 and between the two backlight sources 4 .

[0025] The light guide plate 6 has two opposite light-incident sides 60, and a first installation side 62 and a second installation side 64 located between the two light-incident sides 60 and oppositely arranged. The light side 60 is provided. Typically, in use, the first mounting side 62 is positioned upwards and the second mounting side 64 is positioned downwards. The first mounting side 62 is provided wit...

Abstract

The invention provides a side-in type backlight module which comprises a light guide plate. The light guide plate is provided with a first mounting side and a second mounting side opposite to each other; a first positioning hole, a first positioning slot and a second positioning slot are formed on the first mounting side; a second positioning hole, a third positioning slot and a fourth positioning slot are correspondingly formed on the second mounting side; six rivet columns are arranged on a back plate and are contained in the first and second positioning holes and the first, second, third and fourth positioning slots respectively; the first and second positioning slots are in a right-trapezoid shape, wherein the straight edge of the trapezoid is open, and the bevel edge of the trapezoid inclines downward toward the first positioning hole; the third and fourth positioning slots are in a right-trapezoid shape, wherein the straight edge of the trapezoid is open, and the bevel edge of the trapezoid inclines downward toward the second positioning hole; and the rivet columns in the first, second, third and fourth positioning slots lean on the bevel edge of the trapezoid respectively.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a side-entry backlight module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and control the direction of the liquid crystal molecules through whether the glass substrates are energized or not, and refract the light from the backlight module to produce a picture. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module beco...
