Problems solved by technology

The current practice is to calibrate the corresponding light-emitting device with the preset duty cycle by pre-setting the duty cycle of each color light-emitting device, and pre-setting the time of turning on and off. However, when processing the light-emitting device, every There is a difference in brightness between each light-emitting device, and it is difficult to calibrate the color and color temperature according to the duty cycle to meet the use requirements.

Abstract

The invention discloses a color temperature calibration method, a calibration device and a projection display device. The method comprises: receiving target color coordinates and target brightness representing target colors; multiple brightness; according to the pre-stored corresponding relationship between color brightness and current, combine the multiple brightness and the corresponding relationship to obtain multiple current values; calibrate the color temperature according to the multiple current values. The technical solution of the invention can effectively calibrate the color temperature and meet the use requirements.

Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a color temperature calibration method, a calibration device and a projection display device. Background technique [0002] In projection display, color temperature calibration is usually performed on the color formed by the light emitted by the light-emitting device, and the color temperature represents the color component in the light. The current practice is to pre-set the duty cycle of each color light-emitting device, pre-set the turn-on and turn-off time, and calibrate the corresponding light-emitting device with the pre-set duty cycle. There is a difference in brightness between the individual light-emitting devices, and it is difficult to calibrate the color temperature according to the duty cycle to meet the usage requirements. [0003] The above content is only used to assist the understanding of the technical solutions of the present application, and does n...
