METHOD FOR DRIVING ACTIVE MATRIX ORGANIC LIGHT EMITTING DIODE DISPLAY PANEL
First Claim
1. 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 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.

Abstract
A method for driving an active matrix organic light emitting diode (AMOLED) display panel is provided. In the present method, how to drive a single pixel having a red sub-pixel, a green sub-pixel, a first blue (light blue) sub-pixel, and a second blue (dark blue) sub-pixel is effectively determined based on the characteristics of the (1931) CIE color space. Besides, at the same time point, only one of the two sub-pixels corresponding to the two blues (i.e. dark blue and light blue) in the single pixel is enabled to be mixed with the red sub-pixel and the green sub-pixel. Accordingly, the luminous efficiency of the AMOLED is improved and the power consumption of the entire AMOLED display is reduced.
