Classification: CPC G  H | IPC G  H

Claim 12:
13. A method for controlling a pixel circuit of an array of pixel circuits of a display device, the pixel circuit comprising a plurality of subpixels, the method comprising:
providing an individual emission control signal to each sub-pixel of each pixel in the array of pixel circuits independently to control an emission time and a duty cycle of the sub-pixels, the emission time of said each sub-pixel is Tf*Bfull/Bmj, wherein Tf is a frame time of a frame, Bfull is a brightness of the display device when said each sub-pixel is on at an optimized current density during the frame time and Bmj is the major brightness during frame time,
accessing each row of the array of pixel circuits twice during the frame time, wherein the frame includes a first subframe and a second subframe following the first subframe, the first subframe is divided into a first emission time period and no emission time period following the first emission time period, and the second subframe is divided into a second emission time period and no emission time period following the second emission time period;
wherein the first emission time period is indicative of a first grayscale, the second emission time period is indicative of a second grayscale, the second grayscale is higher than the first grayscale.
