| 发明名称 | System and methods for power conservation for AMOLED pixel drivers | ||
| 摘要 | A system is provided for conserving energy in an AMOLED display having pixels that include a drive transistor and an organic light emitting device, and an adjustable source of a supply voltage for the drive transistor. The system monitors the content of a selected segment of the display, sets the supply voltage to the minimum supply voltage required for the current content of the selected segment of the display, determines whether the number of pixels requiring a supply voltage larger than the set value is greater than a predetermined threshold number, and, when the answer is negative, reduces the supply voltage by a predetermined step amount. | ||

| 主权项 | 1. A method of conserving energy in an AMOLED display having pixels that include a drive transistor and an organic light emitting device, and an adjustable source of a supply voltage for the drive transistor, the method comprising monitoring the content of a selected segment of the display, setting the supply voltage to the minimum supply voltage required for the current content of said selected segment of the display, and determining whether the number of pixels in said selected segment that require a supply voltage larger than the set value, is greater than a predetermined threshold number and, when the answer is negative, reducing the supply voltage by a predetermined step amount. | ||
