Temperature compensation method and system for sensor in display system

Abstract

The invention discloses a temperature compensation method and a temperature compensation system for a sensor in a display system. The method comprises the following steps of acquiring the relationship of an ideal value of collection brightness changing along with the temperature and the relationship of the collection brightness changing along with the temperature; when the present current state of a three-primary color LED (Light Emitting Diode) lamp corresponds to a first current state, acquiring an ideal value corresponding to the current temperature and taking the ideal value as a correction value of the collection brightness which is currently collected by the sensor according to the relationship of the ideal value of the collection brightness changing along with the temperature; if the present current state of the three-primary color LED does not correspond to the first current state, respectively acquiring the ideal value corresponding to the current temperature and the collection brightness according to the ideal value of the collection brightness changing along with the temperature and the relationship of the collection brightness changing along with the temperature; compensating the collection brightness which is currently collected by the sensor according to a predictive formula to obtain the correction value of the currently-collected collection brightness. According to the temperature compensation method and the temperature compensation system for the sensor in the display system, which are disclosed by the invention, the collection value of the sensor can be compensated in real time and is enabled to really reflect the real-time brightness of a display unit.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a temperature compensation method and system for a sensor in a display system. Background technique [0002] With the development of visual information communication technology, the application range of splicing display screens is becoming wider and wider, and users have higher and higher requirements for display effects. Color consistency is an important indicator to measure the display effect of splicing display screens. In the process of using the splicing display, in order to prevent the color of the splicing display from being attenuated by the LED with temperature, each display unit of the splicing display will be equipped with a sensor (sensor) to maintain the splicing display by monitoring and adjusting the brightness of the LED in real time color consistency. [0003] However, the installed sensor is also easily affected by temperature. The measured value will chang...
