Problems solved by technology
[0006] The technical problem to be solved by the present invention is: the existing backlight lighting fixture does not have the problem of versatility, resulting in a serious waste of resources and an increase in cost, and the clamping force of the lighting fixture for the backlight cannot be controlled. There may be cases where the test object is damaged by clamping too tightly, or it may not be positioned by clamping too loosely

The invention relates to the technical field of liquid crystal display design and manufacturing, in particular to a lighting jig for a backlight. According to the lighting jig for the backlight, a backlight clamping device and a flexible printed circuit board press-fitting device are arranged on a bottom board, the backlight clamping device comprises a first clamping mechanism and a second clamping mechanism, and the backlight is clamped between the first clamping mechanism and the second clamping mechanism. Due to the fact that the first clamping mechanism and / or the second clamping mechanism are / is detachably mounted on the bottom board through mounting holes, the distance between the first clamping mechanism and the second clamping mechanism can be adjusted by changing the position of the first clamping mechanism or the second clamping mechanism on the bottom board, the lighting jig can be suitable for backlights of different sizes and specifications, the backlights of various specifications can be subjected to lighting tests or produced, universality of the lighting jig is achieved, and production cost is reduced. Meanwhile, the magnitude of clamping force applied to the backlight can be adjusted through an adjusting assembly, and the accuracy of positioning of the backlight can be kept.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display design and manufacture, in particular to a lighting fixture for a backlight source. Background technique [0002] At present, liquid crystal displays are more and more widely used in various products such as mobile phones and TVs. In order to obtain a uniform backlight and make the brightness of the LCD screen uniform, a backlight lighting fixture is generally required to test the optical properties of the backlight. Performance, so as to determine the relative position and angle of the backlight source and the light source, so that the luminance, angle and uniformity of the light emitted from the backlight source can meet the needs of the liquid crystal display. [0003] Because there are many types of electronic products using LCD screens, the size and shape of LCD screens are also different, and the size and shape of backlight modules that provide light sources for LCD screens ar...
