Patent ID: 8605127

Claim:
A method for driving an active matrix organic light emitting diode (AMOLED) display panel, wherein the AMOLED display panel has at least one pixel, and the pixel has a red sub-pixel, a green sub-pixel, a first blue sub-pixel, and a second blue sub-pixel, the method comprising: determining which one of the first blue sub-pixel and the second blue sub-pixel is enabled according to an inputted 3-dimensional (3D) color signal; and when the first blue sub-pixel is to be enabled, converting a color ratio of the 3D color signal to obtain a set of corrected driving signals for driving the red sub-pixel, the green sub-pixel and the first blue sub-pixel, and disabling the second blue sub-pixel, wherein the step of determining which one of the first blue sub-pixel and the second blue sub-pixel is enabled comprises: capturing an original green component and an original second blue component from the 3D color signal; multiplying the original second blue component by a calculation value to obtain a comparative green component; and comparing the original green component with the comparative green component to determine which one of the first blue sub-pixel and the second blue sub-pixel is enabled.
