Below with reference to the accompanying drawings the invention will be further described with preferred embodiment.
As shown in Figures 1 to 9, the embodiment of the present invention discloses a kind of display device 100 and includes:
Display panel 130 is configured as the sequence controller 200 of driving display panel 130, is stored in the timing control
Image 110, and the external pin of the connection sequence controller 200 are flashed in device 200；Enable signal 120；When the display surface
When plate 130 shows default picture, the sequence controller 200 directly exports the flashing image according to the enable signal 120
110 to display panel 130.
Relative to the best power supply piezoelectricity for adjusting panel by the test support technician for having many flashing images 110
Position, due to flash image 110 substantial amounts, be easy to appear output flashing picture it is incorrect the problems such as.The present invention is to hardware
It does not change too much, the flashing image 110 for being used to adjust common voltage is only added in sequence controller 200 (T-CON),
Style generator need not be set, and since flashing image 110 is that sequence controller 200 is included, it is automatic according to default picture
Occur, flashing image 110 can be exported on correct opportunity, so will not malfunction.
In an embodiment, the sequence controller 200 further includes memory 140 and input and output pin 150；
The flashing image 110 is stored in the memory 140；
The enable signal 120 connects the input and output pin 150；
The sequence controller 200 reads flashing image 110 according to the enable signal 120 from the memory 140,
Then the flashing image 110 is directly exported to display panel 130.
Flashing image 110 is stored in the memory 140 in sequence controller 200, because memory 140 is inherently used for
Flashing image 110 is stored directly in the memory 140 of sequence controller 200 by the reparation element for storing some images and configuration
In, the running of other functions of modules is not influenced, facilitates realization yet.
In one embodiment, the sequence controller 200 further includes bus control unit 160；The memory 140 passes through total
Lane controller 160 is connect with the input and output pin 150.
It is connected in memory 140 by the input and output pin 150 that sequence controller 200 is reserved, bus control unit 160 will
Outside lead is connected with memory 140, illustrates to connect low and high level, when not needing adjustment voltage supplied, output flashing image 110
When, enable signal 120120 drags down, and T-CON is worked normally, and converts after receiving rgb signal through RGBW, with mini low-voltage differential
Signal transmission (mini-Low Voltage Differential Signaling, mini-LVDS) or P-P interface are exported to aobvious
The source driving chip 170 for showing panel 130, is then output in display panel 130；When needing to do flashing adjustment, letter is enabled
When numbers 120 pin is drawn high, T-CON is exported in built-in flashing image 110 to face.
In one embodiment, the memory 140 is band electric erazable programmable read-write memory 140 or flash memory；It is described total
Lane controller 160 is synchronous peripheral interface controller or inter-IC control.
Built-in integrated circuit (Inter Integrated Circuit, IIC) includes a clock line and a data line.
Only a data wire, so being half-duplex operation.Advantage is that wiring is simple, and many equipment can also be hung in both threads.
Synchronous peripheral interface (Serial Peripheral Interface, SPI), by a main equipment and one or more
A to form from equipment, main equipment starts one and the synchronous communication from equipment, so that the exchange of data is completed, data exchange speed
Than very fast.
Memory 140 is band (the Electrically Erasable of electric erazable programmable read-write memory 140
Programmable read only memory, EEPROM), it is the modifiable read-only memory 140 (ROM) of user, can wipes
It removes and reprograms.When how to need to adjust replacement flashing image 110 after guaranteeing, does not need to reconfigure memory 140, show
The durability of panel 130 also will be more permanent.
Flash memory (flash) is a kind of Nonvolatile memory, also can muchly be kept under conditions of the supply of no electric current
Data, storage characteristics are equivalent to hard disk.
In one embodiment, the sequence controller 200 further includes self-testing circuit 210 and test pin, and the test is drawn
Foot is directly connected to the self-testing circuit 210；
The flashing image 110 is stored in the self-testing circuit 210；
The enable signal 120 connects the test pin；
The sequence controller 200 reads flashing image according to the enable signal 120 from the self-testing circuit 210
110, the flashing image 110 is then directly exported to display panel 130.
Because natively there is multiple circulations for burn-in test in 210 module of self-testing circuit of sequence controller 200
Rolling image, increasing a flashing image 110 not will increase cost substantially or is affected, and not change too much to hardware,
And it is automatic to occur, it is not necessary to select, institute since flashing image 110 is the output of self-testing circuit 210 inside sequence controller 200
Will not malfunction.
In one embodiment, the sequence controller 200 further includes data receiver 220, picture quality processing unit
230, overvoltage drive unit 240, row buffering unit 250, switching control unit 260, input and output pin 150, communications pins
170, bus control unit 160 and memory 140；
Display data to be shown pass through the data receiver 220, self-testing circuit 210, picture quality processing unit
230, overvoltage drive unit 240, row buffering unit 250, switching control unit 260 and communications pins 170 are exported to the display
Panel 130；
The bus control unit 160 is separately connected the data receiver 220, self-testing circuit 210, image matter by bus
Measure processing unit 230, overvoltage drive unit 240, row buffering unit 250, switching control unit 260,150 and of input and output pin
Memory 140.
Flashing image 110 is transported to display panel 130 and needs around many cablings because to pass through, to not influence other moulds
The running of block function, and bus control unit 160 is separately connected with the 200 all modules in inside of sequence controller, and it is defeated can to shorten flashing
Out to the time of display panel 130, the flashing state that display panel 130 occurs quickly is adjusted.
In one embodiment, flashing image 110 described in a width is only stored in the self-testing circuit 210.
The picture of multiple circulating rollings of itself is substituted for the flashing image 110 of a restriction in self-testing circuit 210, such as schemes
Shown in 4, when needing self-testing circuit 210 to be connected to high level, 100 freedom of entry mode of whole display device, from regardless of front end
Any signal is exported, this flashing picture is all shown, is selected without multiple images, only one, it is possible to guarantee defeated
Image 110 is correctly flashed out.Flashing image 110 is made in T-CON self-testing circuit 210, entire framework is as shown in figure 5, logical
It crosses enable signal 120 test pin is pulled out to interface and control, when enable signal 120 is low level signal, T-CON is normal
Work, is converted through RGBW after receiving rgb signal, is exported to source driving chip 170, then with mini-LVDS or P-P interface
It is output in display panel 130；When the level of enable signal 120 is drawn high, T-CON starts self-testing circuit 210, and no matter leading portion connects
What the signal of receipts is, T-CON is exported in built-in flashing image 110 (flicker pattern) to display panel 130.
In one embodiment, the display panel 130 includes white sub-pixels 290；The white sub-pixels 290 are being shown
It is alternately distributed in panel 130.
Three sub-pixels compared with common RGB increase a white sub-pixel W, can improve the penetrance of panel, back
Light can be done darker, achieve the purpose that province's power consumption.Also, four sub- pictures make white as shown, parity rows arrange two-by-two
Sub-pixels are more evenly distributed, panel luminance balance.
Refering to what is shown in Fig. 8, a kind of driving method of display device is disclosed as another embodiment of the present invention, it is described
Display device includes display panel and sequence controller, and the driving method includes:
S81, flashing image is prestored in sequence controller；
