Abstract
The invention discloses a high speed panel display method. According to the method, the data decompressed from a first frame is stored before the data is sent to a display module for display. The data of a second frame is sent and is compared with the first frame. If the data of the first frame is the same as the data of the second frame, a flag bit is sent to the display module. Or else, the data is sent to the display module, and covers pixel points of the first frame. The rest can be deduced accordingly for the subsequent frames and pixel points. For a pixel point, when the data of two adjacent frames is the same, the second frame is skipped over without being updated, and the data of the pixel point stored previously is kept. In this way, the updated data bulk of a frame can be significantly reduced, and less time is needed to display the same frame. From another angle, a method for improving the panel display technology is initiated.
Description
Technical field
The present invention relates to a kind of display technique of flat panel display equipment, particularly a kind of display packing that improves flat pannel display speed is applicable to the equipment that has flat panel display terminal.
Background technology
Flat panel display is the general designation of a class technology, comprises that liquid crystal display (LCD), Plasma Display (PDP), electroluminescence show that (ELD), ORGANIC ELECTROLUMINESCENCE DISPLAYS (OELD), Field Emission Display (FED), vacuum fluorescence show (VFD) and light emitting diode tiled display etc.Flat panel display equipment image definition height, the image flicker free can not damage human eye.Existing flat panel display equipment mainly is to show on display screen (panel) by the data (or the data that receive) of coming out decompressing are corresponding one by one, thus, in order to improve display speed, make video display frame smooth more, can only improve display speed by the transfer rate that improves data, and after data rate is brought up to a certain degree, up improve just relatively more difficult again.
Summary of the invention
The purpose of this invention is to provide a kind of high speed panel display method.By a large amount of discovering, just the data of the same painting face to have be identical greatly, it also is identical that quite a few picture element (pixel) data are also arranged in adjacent two frame pictures, and this just provides theoretical foundation for increasing substantially display speed.We in fact not only just can improve dull and stereotyped display speed by the transfer rate that improves data, can also show the method for a same frame picture by few " refreshing " some data as far as possible, thereby improve dull and stereotyped display speed.
Realize that technical scheme of the present invention is: a kind of high speed panel display method, show that module shows the data that receive one to one on display panel, described demonstration module does not scan the same picture element identical with data in the former frame picture, keeps the data of described same picture element former frame picture; The different pixel point datas of data cover this pixel point data of former frame; Described demonstration module shows data map to display panel.
This technical scheme also comprises: the pixel point data of described adjacent former frame picture is stored in the storage space, and comparer compares the data that transmit and the previous frame data in the storage space, and with result transmission relatively to showing module; The data of the adjacent two frame pictures in the front and back of described same picture element are identical, transmit zone bit to described demonstration module; The data difference of the adjacent two frame pictures in the front and back of described same picture element then directly transmits data to described demonstration module, simultaneously this pixel point data is saved in storage space, the data before covering.
Described demonstration module receives zone bit, the display screen display circuit of not bothering to see me out, and the picture element counter adds 1 simultaneously, prepares to receive the data of next pixel; Described demonstration module receives data, send the display screen display circuit, and the picture element counter adds 1 simultaneously, prepares to receive the data of next pixel.
Concerning showing module, in order to support this more high-level efficiency data transmission, demonstration, show that module need support to skip this picture element (not removing to scan this picture element) to receiving when being zone bit, directly carry out the reception of next pixel data.
For same picture element (pixel), when adjacent two frame picture datas are the same, show that module does not scan this picture element, directly skip, do not remove to refresh this pixel point data, and keep the data of this picture element former frame picture storage, like this, the data volume that refreshes of one width of cloth picture just can reduce greatly, on the another one angle, has just used less time to show a same picture.
The invention has the beneficial effects as follows: the present invention need not to refresh the view picture picture, only refresh different pixel data in the two frame pictures of same picture element front and back, reduced the data volume that refreshes a width of cloth picture significantly, more traditional transfer rate with the raising data, the present invention has opened up the method that improves flat panel display from the another one angle with innovating.

Fig. 2 is that demonstration module of the present invention receives the data theory diagram;
Fig. 3 is a software design process flow diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 3, the data that video data comes out through decompressing compare module by storage and connect the demonstration module, by display panel video pictures are shown again.The storage relatively function of module is: the graph data of adjacent two frame pictures before and after the same picture element is compared, and information relatively is sent to the demonstration module; Send the former frame data of data and storage when identical, send zone bit to arrive the demonstration module; The former frame data that send data and storage not simultaneously, data that directly will back one frame are sent to the demonstration module.The function that shows module is: receive by storage and compare the data message that module sends, when the reception data are zone bit, the panel display circuit of not bothering to see me out, the data of this picture element remain unchanged on the display panel, but the pixel counter adds 1, prepares to receive the data message of next pixel; Receive be graph data the time, send panel display circuit, the former frame picture data is covered by back one frame picture data on this picture element of display panel, the pixel counter adds 1 simultaneously, prepares to receive the data message of next pixel.Thus, in the view picture picture of flat pannel display, the pixel data of front and back frame same frame remains on the display panel at one time, the former frame data of the picture element of picture part inequality by the back one frame data covering mappings to display panel.
The data that the first frame picture decompresses out store earlier, and deliver to and show on the module and show.The second frame picture data brings elder generation and first frame compares, and data are the same, just transmits a zone bit and give the demonstration module; If different, then transmit data and give the demonstration module, cover first this picture element of frame picture with these data simultaneously.The picture of back and picture element are by that analogy.
Decoded video data compares module through storage and connects the demonstration module again.
Above-mentioned described embodiment is preferred embodiment, but the invention is not restricted to above-mentioned specific embodiment, and some identical or replacement schemes that those of ordinary skill in the art can expect apparently all should fall into the scope that invention is protected.
