LIGHT SOURCE CONTROL METHOD FOR DISPLAY DEVICE, AND DISPLAY DEVICE

WIPO Patent Application WO/2020/151629

A1

Provided is a display device (10), comprising an array light source (100). The array light source (100) comprises a plurality of light-emitting modules (110) that emit excitation light. Each of the light-emitting modules (110) comprises a plurality of edge light-emitting modules (111) distributed along an edge of the array light source (100), and a plurality of central light-emitting modules (112) surrounded by the edge light-emitting modules, and the maximum light-emitting intensity of the edge light-emitting modules (111) is greater than the maximum light-emitting intensity of the central light-emitting modules (112), thereby improving the display picture edge distortion caused by fluorescence diffusion. Further provided is a light source control method. The light-emitting power of the light-emitting modules is gradually increased by means of an iterative algorithm until the light-emitting intensity of all light-emitting modules satisfies the display brightness required by an image to be displayed, thereby reducing light loss.
