Abstract

The invention relates to a display driver, a recording method thereof and a display. The recording method comprises the following steps: providing recording data; providing a display buffer in the display driver, wherein the display buffer is used for preliminarily storing display data in the display time; providing a non-volatile memory, wherein the non-volatile memory is coupled to the display buffer by a data bus bar; and running a recording program, wherein the recording program contains the following actions: inputting the recording data to the display buffer and recording the recording data from the display buffer to the non-volatile memory by the data bus bar. The invention has the advantages that the display buffer which is originally and internally established in a display driving circuit is applied to replace a temporary memory for establishing a recording programmable memory unit. In the mode, the functions of the original display driving circuit can not be influenced, and the advantage of reducing the area can be achieved.

Description

Technical field [0001] The present invention relates to a display-related technology, and particularly relates to a programming method of a display driver and a display driver using the same. Background technique [0002] With the advancement of science and technology, electronic technology has evolved from the earliest vacuum tubes and transistors to integrated circuit chips. Its uses are very wide, and therefore, electronic products have gradually become indispensable necessities in modern life. At the same time, the relationship between electronic technology and the development of displays is getting closer and closer. At present, flat-panel displays have become an indispensable necessity in daily life. For example, in the application of large-size LCD displays, including: LCD TVs, LCD computer monitors ; In the application of small and medium-sized liquid crystal displays, including: mobile phones, personal digital assistants, and even digital music players and so on.
