Abstract
The invention discloses a method for removing an LCD flash phenomenon, and the method comprises the following steps: a computer, a signal generator, a fire card and a color analyzer are prepared; the fire card is connected to a display by a VGA line, the computer is connected with the fire card by a print line, the signal generator is connected to the fire card by a signal line, the color analyzer is connected to the computer by a USB line, and the computer and the signal generator are connected by a serial port line; the computer is used for running an adjustment program, reading an FLIC value from the color analyzer and sending a DDCCICommand by the fire card to change a VCOM value of the LCD, thus adjusting the FILC value of the LCD; and by adopting an asymptotic manner, the change of V-COM data is realized, and the FILC value is measured by the color analyzer until the measured datum is the minimum. By compiling programs and utilizing the computer, the color analyzer, the fire card and the like, the VCOM value of the display is adjusted, thus adjusting the FILC value of the display and ensuring the picture effect to be optimum.
Description
[technical field]
The present invention relates to the LCD picture regulation technology, be meant a kind of method of eliminating the LCD picture scintillation especially.
[background technology]
Scintillation appears in the picture of LCD sometimes, and this is because the picture displayed GTG has slight change when each frame update, so allow human eye experience picture in flicker.Scintillation is closely related with conditions such as the brightness of the residing environment of display, temperature, humidity, has eliminated the LCD of scintillation under a certain condition, may occur scintillation once more if be placed on to use under another environmental baseline.
Because the appearance of scintillation can have a strong impact on the display effect of LCD, therefore in order to eliminate scintillation, guarantee the display effect of LCD, a VCOM parameter is arranged in LCD, by can accomplish the change of VCOM voltage to the adjusting of VCOM parameter, can reach the purpose of eliminating scintillation.As shown in Figure 1, what adopt at present is that the Filck Pattern (the special-purpose picture of the test pictures flicker that panel producer makes) that directly uses Chroma (signal generator) output specific gives LCD, then by manual adjustment VCOM voltage, with the mode of range estimation, make picture effect reach best.The shortcoming of this scheme is: use manual adjustment VCOM value, and visual detection film flicker situation, this scheme out of true and speed are slow.
[summary of the invention]
Technical matters to be solved by this invention is to provide a kind of method of accurate elimination LCD picture scintillation.
The present invention solves the problems of the technologies described above by the following technical solutions:
Eliminate the method for LCD picture scintillation, comprise the steps:
Step 1: prepare a computer, a signal generator, a writing card, a color analyzer; Described writing card is connected to LCD by the VGA line, described computer expert crosses print wire and connects described writing card, described signal generator is connected to described writing card by signal wire, described color analyzer is connected to computer by the USB line, and described computer is connected by Serial Port Line with described signal generator;
Step 2: described computer is used to move the adjustment program, reads the FLIC value from described color analyzer, and sends the VCOM value that DDCCI Command is used to change LCD by described writing card, thereby adjusts the FILC value of LCD;
Step 3: by asymptotic mode, realize the variation of V-COM data, carry out the measurement of FILC value, till the data minimum of measuring by color analyzer.
The model that described color analyzer uses is CA-P12/15 or CA-PS12/15.
The invention has the advantages that: by coding, utilize instruments such as computer, color analyzer, writing card, reach and adjust display VCOM value, and then adjust the FILC value of display, make its picture effect reach best.
[description of drawings]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is that V-COM adjusts connection diagram in the prior art.
Fig. 2 is that V-COM adjusts connection diagram among the present invention.
[embodiment]
Eliminate the method for LCD picture scintillation, flashing for the picture of LCD resembles, and can use the picture of specific signal generator output, uses color analyzer CA210 (CA-P12/15 or CA-PS12/15) to record.Under the FLIC of color analyzer CA210 pattern, can see the flicker number of times of picture per second.In addition, the VCOM parameter is set to adjustable, by adjusting the VCOM value, can change the FILC value of LCD.In the liquid crystal display-driving program, the DDCCI Command that Open V COM adjusts, and in factory's menu, show, so far, can use DDCCICommand to change VCOM value product method and change VCOM, thereby change the FLIC value of LCD.
Use PC, send out DDCCI Command by writing card and give LCD to change VCOM; Use PC to read the FLIC value that color analyzer CA210 test obtains by USB interface.So, by coding, utilize instruments such as PC, color analyzer CA210, writing card, reach and adjust LCD VCOM value, and then adjust LCD FILC value, make its picture effect reach best.PC is used to move the adjustment program, reads the FLIC value from color analyzer CA210, and sends the VCOM value that DDCCI Command is used to change LCD by writing card; Color analyzer CA210 can only use CA-P12/15 or these two kinds of models of CA-PS12/15, is used to read the FLIC value of the current picture of LCD; Signal generator one is used from and produces specific test signal, promptly uses PC to pass through DDCCI Command and adjusts VCOM, thereby reach the effect of the FILC that adjusts LCD, has overcome because of VCOM to be provided with that bad to cause picture to dodge bad "
Specifically comprise the steps:
Step 1: prepare a computer (PC), a signal generator, a writing card, a color analyzer; Described writing card is connected to display by the VGA line, described computer expert crosses print wire and connects described writing card, described signal generator is connected to described writing card by signal wire, described color analyzer is connected to computer by the USB line, and described computer is connected by Serial Port Line with described signal generator; As shown in Figure 2.
Step 2: described computer is used to move the adjustment program, reads the FLIC value from described color analyzer, and sends the VCOM value that DDCCI Command is used to change display by described writing card, thereby adjusts the FILC value of Monitor.
Step 3: by asymptotic mode, realize the variation of V-COM data, carry out the measurement of FILC value, till the data minimum of measuring by color analyzer.
Described color analyzer uses CA-P12/15 or these two kinds of models of CA-PS12/15.
The present invention utilizes instruments such as computer, color analyzer, writing card by coding, reaches to adjust display VCOM value, and then adjusts the FILC value of display, makes its picture effect reach best.
