Embodiment Construction

[0028] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the backlight module is mainly composed of a light source (not shown in the figure), a light guide plate 3, an optical film material 2, and structural components. Structural components such as backlight module frame 4, light-shielding double-sided adhesive tape 5, etc. The optical film material 2 includes a diffusion sheet, a prism sheet, and the like.

[0030] Such as figure 2 As shown, the present invention provides a backlight module material reliability test fixture, including a fixture base 6 and four fixture side frames, and the four fixture side frames are all arranged on the upper surface of the fixture base 6 , and are vertically connected to each other in turn to form a cavity structure. After the cavity structure of the test fixture is assembled, the material to be tested for the ...

Abstract

The invention relates to a backlight module in the field of display, in particular to a backlight module material reliability test fixture. The test fixture comprises a fixture base and four fixture side frames, and the four fixture side frames are arranged on the top surface of the fixture base and sequentially perpendicularly connected with one another, so that a cavity structure is formed. The test fixture can more quickly and more efficiently test the reliability of optical materials, greatly shorten the development cycle and decrease the risk of development; because the structure design of the adjusting side frames is adopted, the applicable testable size range is wide, the test fixture can be freely adjusted according to design sizes, so that the test fixture can be applied to test a number of products with different sizes, and thereby the cost is greatly reduced.

Description

technical field [0001] The invention relates to a backlight module in the display field, in particular to a material reliability test fixture for the backlight module. Background technique [0002] Currently, in flat panel display technology, since a liquid crystal display (LCD) itself does not emit light, a backlight module is essential for a transmissive LCD. [0003] Backlight Unit (BLU) is a light-emitting module located behind the liquid crystal display, and its light-emitting effect will directly affect the visual effect of the liquid crystal display module. LCD itself does not emit light, it displays graphics or characters is the result of its light modulation. [0004] Such as figure 1 As shown, the backlight module is mainly composed of a light source (not shown in the figure), a light guide plate 3, an optical film material 2, and structural components. Structural components such as backlight module frame 4, light-shielding double-sided adhesive tape 5, etc. Th...
