Claim Text:
1. A method of reducing burn-in effects in an array of organic light-emitting diode display pixels in a display, comprising: receiving image data with communications circuitry in a display driver integrated circuit; storing the image data in memory using the communications circuitry; with control circuitry on the display driver integrated circuit, determining whether the image data is static; with a display controller on the display driver integrated circuit, displaying the image data on the array of organic light-emitting diode display pixels while minimizing display burn-in effects in the array of organic light-emitting diode display pixels by responding to information from the control circuitry indicating that at least some of the image data is static, wherein determining whether the image data is static comprises detecting a static frame of data in the memory, and wherein storing the image data in the memory comprises issuing a write command with a decoder in the communications circuitry; with the control circuitry, monitoring for the write command issued by the communications circuitry, wherein the control circuitry includes a countdown timer; resetting the countdown timer in response to detection of the write command by the control circuitry; and asserting a static image data present flag with the control circuitry in response to expiration of the countdown timer.
