Abstract

The present invention provides a fixing structure and a display brightness detection device. The fixing structure is used for fixing a reflective sheet to a photosensitive detection component, so as to maintain a preset distance between the reflective sheet and the photosensitive detection component; the The fixing structure includes at least one clamping unit for clamping and fixing the reflection sheet, and has a first state and a second state. In the first state, the clamping unit clamps the reflection sheet, and in the first state, the clamping unit clamps the reflection sheet. In the second state, the clamping unit releases the reflection sheet. The fixed structure and the display brightness detection device of the present invention can keep the distance between the reflection sheet of the backlight module and the photosensitive detection component relatively unchanged, and solve the change in the distance between the reflection sheet and the brightness sensor due to the deformation of the reflection sheet and other reasons. , which causes the problem of inaccurate detection data of the brightness sensor.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fixing structure and a display brightness detection device. Background technique [0002] Some displays in special fields, such as medical surgical displays, need to detect the brightness of the screen, and adjust or correct the display effect according to different brightness through algorithms to ensure the best display effect. This requires detection of the brightness of the backlight of the display. Usually, a photosensitive detection component is used to detect the brightness of the backlight of the display. When detecting the brightness of the backlight, a hole is opened on the backplane of the backlight module, and the brightness sensor is placed in the hole of the backplane to detect the brightness of the backlight after passing through the reflector. Use this brightness to calculate the display screen brightness. In this way, the detected brightness value behind the...
