Generally, in the LCD module, has the video memory that shines upon (mapping) with each pixel of LCD panel at 1: 1, no matter whether the data of the video memory in the LCD panel are upgraded, the capital with the very short cycle (for example: 30fps) scan image memory, shown by the LCD panel, on the terminating machine main frame, brought in constant renewal in the data of above-mentioned video memory.
But, if a pixel data of video memory upgrades, the LCD panel pixels of respective pixel data mappings also will update displayed, if during 260,000 coloured silks (262k color) LCD, the data of a pixel only reach 18 bit (R, G, each 6 bit of B) time, could demonstrate color fully.
That is, as shown in Figure 1, in above-mentioned pixel data, 2 bytes (16 bit * 2) are divided into R, G, the B data transmit.For example, in 1 byte, the R data have occupied 6 bits, and the G data have occupied 3 bits, also have the junk data of 7 bits in addition; In 1 other byte, the G data have occupied 3 bits, and the B data have occupied 6 bits, also have the junk data of 7 bits in addition.
Therefore, use 16 common bit berths (berth), the image LCD of LCD module transmission pixel data in the terminating machine main frame is because transmit the data that a pixel data need transmit 2 bytes, so transmit the data of 32 bits, just need to spend considerable time.
That is, pixel data is not disposable continuous transmission, transmits for twice but be divided into, this wherein just includes junk data, like this, (for example: the read/write time of 14 bits), this is the place of problem to upgrade the phenomenon that the demonstration of pixel data will generation time lags behind.
In other words, corresponding 16 Bit datas of the sweep speed of LCD panel upgrade when keeping stablizing, the pixel data renewal speed of video memory is slow (renewal speed of 32 bits), and the display speed of whole image also can be slower, problems such as pixel data flicker will occur.
Summary of the invention
The present invention develops in order to address the above problem, purpose provides a kind of quantity of data in terminating machine functional diversity and the picture and trend that renewal speed is constantly accelerated of adapting to, improve renewal speed, the minimizing picture incompleteness of liquid crystal panel pixel data, show the picture data update method of the mobile communication terminal of nature picture.
In order to realize the foregoing invention purpose, the present invention in the characteristics aspect the method that improves mobile communication terminal liquid crystal panel display speed is, in mobile communication terminal main frame inside, when constituting the video memory transmission pixel data of liquid crystal panel module, in the byte data that constitutes each pixel data, only read, transmit effective bit.
The object of the invention provides a kind of method, promptly, when video memory transmits 1 pixel data that is made of 2 bytes, direct control program calculator, do not read the next junk data that does not use in the rapid data, but directly read, transmit next valid data, read the time that junk data consumes thereby can reduce.
For achieving the above object, technical scheme of the present invention is:
In improving mobile communication terminal liquid crystal panel display speed method,
In described mobile communication terminal main frame, when constituting the video memory transmission pixel data of liquid crystal panel module, program counter only reads and transmits significant bit in the byte data that constitutes each pixel data, program counter read and the end of transmission significant bit after, skip the junk data in the byte data of pixel data, directly read and transmit significant bit in next byte data.
Described program counter is to use assembler language to control.
Reading end pointer at the significant bit of described byte data is to read and judge the data bit of setting (9 bit) in the byte data of 16 bit sizes.
After each significant bit of described pixel data utilizes pointer to specify initial pointer, adopt the mode that increases the address automatically, continuously the data below the transmission.
Beneficial effect of the present invention is, can adapt to the quantity of data in terminating machine functional diversity and the picture and the development trend that renewal speed is constantly accelerated, and can improve liquid crystal panel pixel data renewal speed, reduce the picture incompleteness, shows the nature picture.
