Display driving device and display driving method

Abstract

The invention provides a display driving device which comprises an MPU (Microprocessor Unit) interface, a function module, an image storage module, a grid electrode driving module, a source electrode driving module, a power supply module, a gray-scale reference voltage module, a control register module and a first control device, wherein the first control device is connected with the control register module and is used for converting addresses of a control register to adapt to the change of target driving program. Preferably, the first control device comprises programmable register address arrays which comprise a plurality of address code registers, a decoding controller and a programmable module. The invention also provides corresponding handheld equipment and a panel display driving method. The invention replaces an identification number unit of a chip by the programmable module and can realize flexible customization through the mold group end according to the actual requirements, so the traditional driving program can be compatible and can be invoked, thereby the invention can reduce the development workload of scheme vendors, shortens the development period and can relatively reduce the burden in the aspects of cargo purchasing and cargo preparation.

Description

technical field [0001] The present invention relates to a driver chip, in particular to a driver device for a display screen of a handheld device, in particular to a universally designed display driver device compatible with existing driver programs and a panel display driver method. Background technique [0002] Among the driver chips of many small size and resolution (QVGA, WQVGA, etc.) Universal driver chip design to reduce the complexity and workload of back-end applications to facilitate the update speed of current handheld devices. In practical applications, if a certain generality is to be achieved, the dependence on the driver program must be reduced. At the same time, compared with the driver program, the driver part necessary for the hardware should be flexible and changeable. [0003] In the prior art, those skilled in the art understand that in each application system, several kinds of driver programs are generally installed. When the system starts to work, the ...

Problems solved by technology

However, since the identification number (ID) of the driver chip itself cannot be changed at will in the prior art, it is impossible to call the corresponding driver and be compatible with general-purpose drivers in practical applications.
