LED liquid crystal display screen direct type backlight source detection device and detection method thereof

Abstract

The invention discloses an LED liquid crystal display screen direct type backlight source detection device and a detection method thereof, and relates to the technical field of backlight source detection. The detection device comprises a detection table, wherein an interface connected with a backlight source is arranged on the detection table, a groove is formed in the top of the detection table, a placing plate penetrates through the inner side of the groove in the top of the detection table and the inner side of the groove is in sliding connection with the placing plate, the bottom of the placing plate is fixed to one end of a spring A, and the other end of the spring A is fixed to the top of the detection table; and a fixing assembly for fixing the backlight source and a driven assembly for controlling the fixing assembly are arranged in the detection table, and a cross rod is fixed on the inner wall of the detection table. The driven assembly is matched with the fixing assembly, so that when the backlight source is placed on the placing plate, the placing plate is pressed downwards, the clamping plate can be controlled to fix the backlight source; and thus, the problems that it is troublesome to fix the backlight source through bolts conventionally, and the detection efficiency is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of backlight detection, in particular to an LED liquid crystal display direct-lit backlight detection device and a detection method thereof. Background technique [0002] The backlight is a light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. The LCD itself does not emit light, it displays graphics or the result of its modulation of light. In the design of the backlight source, the selection of the light source used is very important. The light source used determines the photoelectric parameters such as power consumption, brightness, and color of the backlight, and also determines its use conditions and service life. [0003] In the structural design of the LCD display, the selection of the backlight source is very critical. The selected backlight source determines the power consumption, brightness, colo...

AI Technical Summary

Problems solved by technology

[0004] When testing the existing LED liquid crystal display direct-type backlight, it is necessary to fix the backlight. The existing detection device is more troublesome to fix the backlight. At the same time, the detection efficiency of the backlight is reduced. In view of this, we propose a LED liquid crystal display direct-down type backlight detection device and its detection method.
