PIXEL DRIVE APPARATUS, LIGHT-EMITTING APPARATUS AND DRIVE CONTROL METHOD FOR LIGHT-EMITTING APPARATUS |
摘要 |
A pixel drive apparatus to drive a pixel has a function of compensating a change in characteristics of the pixel. The pixel includes a light-emitting element and a drive control element to drive the light-emitting element. The pixel drive apparatus acquires the electrical characteristic parameter that is used to compensate variation of electrical characteristics of the light-emitting drive circuit including the drive control element based on a voltage value of the detection voltage after applying a voltage having a voltage value exceeding a threshold voltage across the drive control element to elapse of at least one relaxation time, and acquires a light-emitting characteristic parameter that is used to compensate variation of characteristics of the light-emitting element based on light-emitting luminance of the light-emitting element that is operated to emit light in accordance with luminance measurement image data corrected based on the electrical characteristic parameter. |
