Classification: CPC G  H | IPC G  H

Claim 0:
1. A display device comprising:
an array of pixels, wherein each pixel includes a plurality of sub-pixels arranged in a matrix; and
a driving circuitry configured to provide an individual emission control signal to each sub-pixel of each pixel in the array of pixels to independently control an emission time and a duty cycle of each sub-pixel, 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 an optimized current density during the frame time, and Bmj is a major brightness during frame time;
wherein each row of the array of pixels is accessed twice during the frame time, 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.
