Abstract
The invention relates to a designing project which comprises a DSub (computer video signal) input interface, a CVBS (compound television video signal) input interface, a SDRAM storage, a FLASH storage, a CPU, an image processor and a EEPROM chip. It provides a TFT liquid crystal display fast matching method.
Description
Affiliated technical field
The invention belongs to the liquid crystal display terminal technical field, relate to the TFT LCD and realize quickly configuration method.
Background technology
Along with the fast development in digital information epoch, progressively the widening and go deep into of computer system application scope, display device has become the requisite support equipments in field such as commerce and trade, Industry Control, armament systems.As LCD have gently, approach, antivibration and energy-saving advantages, LCD in the application of each application scenario more and more widely requires to propose a kind of design, debugging, production and maintaining method of fast and convenient TFT LCD.
Because there is a lot of TFT LCDs manufacturing firm in the whole world; the design of their TFT LCDs, manufacturing process respectively have protection patent and performance characteristic; dimensions is also varied, causes the configuration parameter of TFT LCDs of each manufacturing firm variant each other.Therefore in design, debugging, production and maintenance process, at the TFT LCDs of different manufacturing firms and different size specification, their vision signal is handled and the display control circuit plate substantially can't be general, causes design complicated, cost is too high, and the production maintenance is very inconvenient.
Summary of the invention
The purpose of this invention is to provide a kind of TFT LCD and realize quickly configuration method, make in this way and can carry out the fast parameter configuration to the TFT LCDs of various manufacturing firms and dimensions according to unified screen ginseng form.At the TFT LCDs of different manufacturing firms and different size specification, processing of their vision signal and display control circuit are firm and hard existing general.
Concrete technical scheme of the present invention is as follows:
We find to mainly contain in the screen ginseng following essential configuration parameter through the multiple typical TFT LCDs that the famous manufacturing firm of the sufficient theoretical analysis and the investigation whole world produces:
DCLK: Dot Clock=Htotal*Vtotal* field frequency;
HTotal: the physical line resolution of sampled data;
Vtotal: the physical field resolution of sampled data;
HActive Width: the physical line resolution of screen;
HActive Start: the physical line reference position of screen, when decision begins to show from HSYNC;
VActive Width: the physical field resolution of screen;
VActive Start: the physical field reference position of screen, when decision begins to show from VSYNC;
HSYNC Width: the width of setting the HSYNC pulse;
VSYNC Width: the width of setting the VSYNC pulse;
HSYNC Front Porch: the width of setting the pulse of HSYNC crop;
VSYNC Front Porch: the width of setting the pulse of VSYNC crop;
HSYNC Back Porch: the width of setting the pulse of HSYNC back porch;
VSYNC Back Porch: the width of setting the pulse of VSYNC back porch;
HSYNC polarity: the polarity of setting the HSYNC pulse;
VSYNC polarity: the polarity of setting the VSYNC pulse;
DE polarity: the polarity of setting the DE pulse.
For different TFT LCDs, configuration parameter is kept among the EEPROM (adopting the above model of AT24C04), concrete second page (must preserve the EDID supplemental characteristic for first page) of preserving the position at EEPROM, some disappearance parameter item adopts 0XAA/170 (these data are not used) expression in the TFT LCDs databook in the configuration parameter of reality, and adopts the DDC2BI standard at the parameter method for refreshing of production run and maintenance phase.
Accompanying drawing and drawing explanation
Fig. 1 is that hardware of the present invention is realized synoptic diagram;
Fig. 2 is that software of the present invention is realized synoptic diagram.
Embodiment
With reference to Fig. 1, expression TFT LCD realizes the hardware realization synoptic diagram of quickly configuration method, and one road computer video DSub signal is through the ADC module, and one road television video frequency signal CVBS is through Decoder module Dec, enter presentation manager, under the support of SDRAM, carry out Video processing; Wherein the functional parameter of various piece is provided with by CPU by OSD, and configuration parameter is kept among the EEPROM (adopting the above model of AT24C04).
With reference to Fig. 2, realize synoptic diagram for software of the present invention, at first be the parameter setting of reading EEPROM parameter and various piece; The user receives the OSD order, carries out function corresponding according to the order classification and handles.
