Backlight detection device and detection method

A backlight detection device, comprising:

• a carrier plate, having a backlight detection region for carrying a backlight to be detected;
• a light property detection plate with a plurality of brightness sensors arranged thereon, configured for detecting light properties of different regions of a backlight to be detected which is positioned in the backlight detection region;
• and
• a data processing unit, in signal connection with the plurality of brightness sensors, configured for judging whether the light property of the backlight to be detected is qualified or not according to a plurality of brightness signals of different regions of the backlight to be detected which are detected by the plurality of brightness sensors,
• wherein the carrier plate is provided with a pillar and a support block, the pillar and the support block are positioned on two opposite sides of the backlight detection region, the light property detection plate is rotatably connected to the pillar, the light property detection plate is configured to rotate in a plane substantially parallel to the carrier board, and the light property detection plate is detachably connected to the support block.

A detection method adopting a backlight detection device, the backlight detection device comprising:

• a carrier plate, having a backlight detection region;
• a light property detection plate with a plurality of brightness sensors arranged thereon, configured for detecting light properties of different regions of a backlight to be detected which is positioned in the backlight detection region;
• and
• a data processing unit, in signal connection with the plurality of brightness sensors, configured for judging whether the light property of the backlight to be detected is qualified or not according to a plurality of brightness signals of different regions of the backlight to be detected which are detected by the plurality of brightness sensors,
• the detection method comprising:
• placing a backlight to be detected on the backlight detection region of the carrier plate and lighting the backlight to be detected;
• positioning the light property detection plate directly above the backlight to be detected, wherein the plurality of brightness sensors detect brightnesses of different regions of the backlight to be detected simultaneously;
• and
• by the data processing unit, judging whether light property of the backlight to be detected is qualified or not according to a plurality of brightness signals of different regions of the backlight to be detected which are detected by the plurality of brightness sensors,
• wherein the by the data processing unit, judging whether light property of the backlight to be detected is qualified or not according to a plurality of brightness signals of different regions of the backlight to be detected which are detected by the plurality of brightness sensors, includes:
• if a minimum brightness signal value of the plurality of brightness signals of different regions of the backlight to be detected which are detected by the plurality of brightness sensors is greater than or equal to a preset standard brightness value, and a ratio of the minimum brightness signal value to a maximum brightness signal value of the plurality of brightness signals is greater than or equal to a standard ratio, determining the light property of the backlight to be detected is qualified by the data processing unit;
• otherwise, determining that the light property of the backlight is unqualified.
