Abstract

The invention relates to a correcting device of an ambient light sensor, which comprises a light source, an optical splitter, a first light pipe, at least one second light pipe and at least one vernier device, wherein the light source is used for outputting light beams with different illuminance; the optical splitter is provided with an input face and an output face; the two ends of the first light pipe are respectively coupled to the light source and the input face of the optical splitter, and the first light pipe is used for transmitting the light beams emitted by the light source to the optical splitter; each second light pipe comprises an inlet end and an outlet end, and the inlet end of each second light pipe is coupled to the output face of the optical splitter; and the outlet end of each second light pipe can be movably arranged in the corresponding vernier device. The correcting device of the ambient light sensor can reduce the time required for correcting the ambient light sensor.

Description

technical field [0001] The invention relates to a correction device, in particular to a correction device for an ambient light detector. Background technique [0002] Flat-panel displays have been widely used to replace cathode ray tubes and are used in TV or computer screens to become a new generation of display devices. Therefore, the needs of various flat-panel displays, including liquid crystal displays (LCDs), plasma displays (PDPs) ) and organic electroluminescent displays (OLEDs) are rapidly increasing. Among them, liquid crystal displays have a higher penetration rate. [0003] The liquid crystal display mainly includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel of the liquid crystal display does not emit light, the backlight module needs to be used to provide the display light source required by the liquid crystal display panel. Therefore, the quality of the display light source provided by the backlight module is...
