Methods and apparatus for driving matrix display panels

摘要

Systems and methods for realizing display drivers, especially OLED drivers having a high efficiency. With a single pass, using an algorithm based on simple equations based on gathered maximum display data, the driver can split an image to be displayed into multiple planes and tiles thus balancing peak current consumption. Furthermore the driver is able to optimize drive time periods in regard of many parameters.

1. A method to achieve an efficient display driver using a simple computation with a minimal number of computation passes, comprising the following steps:
(1) providing a display device, comprising row and column drivers and power supply, a processor, an input device, a memory device, and a data storage device; (2) loading pixel values of an image matrix, having rows and columns, to be displayed into the data storage, wherein the image can be decomposed into a number of tiles; (3) computing in a single pass pixel values to support splitting the image into different planes, wherein each tile can be processed in parallel; and (4) displaying sequentially the different planes of the image.
