Display screen (LCD liquid crystal display screen) left and right of thin film transistor (TFT) (Thin Film Transistor, TFT) type in the prior art
The upper width for having certain black surround below, the black surround is exactly the region that can not show content.As shown in figure 3, because mobile whole
Panel (Panel) binding of end downside has display driver chip, and downside black surround will be wide than the black surround of other sides, the size of chip
Also the width H of downside black surround is significantly impacted.
The pixel of a TFT of Panel includes red (R), green (G), blue (B) three sub-pixels, the Panel picture of existing maturation
Plain permutation technology is shared source electrode (Source) data line of sub-pixel of each column, and Panel pixel under double grid line panel
Arrangement is that the sub-pixel of every two column shares a source data line.In this way if using equal resolution display screen, display drive
The source data of dynamic chip can reduce half, and the area of display driver chip can reduce, and may be implemented to subtract narrow downside black surround
Width H.
Panel uses double grid line panel, according to the power consumption calculation formula of display driver chip:
Wherein: capacitor C is the parasitic capacitance on Panel Source data line, and voltage V is Panel Source data line
On voltage, frequency f is that Panel Source data line powers on the negative change frequency of positive pressure.
The liquid crystal of Panel completes the data scanning of a line sub-pixel, Dual GatePanel using column overturning scan pattern
Every Source data line on the positive and negative change frequency of voltage be twice of existing Panel mature technology, a while son
Pixel can be considered a parasitic capacitance C, then the capacitance on every Source data line also doubles.Such as mobile phone uses
The mould group of FHD resolution ratio, FHD mould group has 1920 row pixels, then the Panel of Dual Gate will lead to display driver chip function
Consumption theoretically increases 1920*2 times relative to existing Panel mature technology.Therefore, the power consumption of display driver chip is larger, thus
Cause the power consumption of mobile terminal larger.

As specific embodiment, using mobile terminal as mobile phone, first kind sub-pixel is odd rows, the second class
Sub-pixel be even number line sub-pixel for, the display driving method of the embodiment of the present invention the specific implementation process is as follows:
Firstly, as shown in figure 8, cell phone system CPU obtains a frame image data from the GRAM1 of memory block is output to GPU,
GPU is calculated and is parsed total line number 2n of image；GPU is by the image odd row data (G of a frame1、G3、……、G2n-3、G2n-1)
Memory block GRAM2 is extracted and is stored in identification, marks the memory block GRAM2 end address location identifier E1 at this time.The frame image is even
Several rows of data (G2、G4、……、G2n-2、G2n) image data GRAM2 is stored in since the E1 of memory block address location.Such CPU
Cell phone system end image odd-numbered line and the arrangement storage of even number line image data are just completed with GPU.In order to avoid transmitting data exception
Capable situation (such as common ESD interference signal) is lost in appearance, and then the demodulation of display driver chip end is caused odd-numbered line and even number occur
Control error, so in the G of deposit2n-1Data end increases identifier HE, and display driver chip identification odd-numbered line can be allowed sub
Pixel and even number line sub-pixel separation guarantee the accuracy of odd rows and even number line sub-pixel Time-sharing control point.
Then, as shown in figure 5, cell phone system GPU obtains that treated from GRAM2 image data, passes through image data
Bus interface exports a frame image data line by line.
Finally, as shown in figure 9, the frame image data that display driver chip reception GPU is sent, is demodulated line by line and is deposited
Enter data buffer area (FIFO).As shown in Figure 10, original state, Y and OE_SYNC signal value output are 0, so or door output EN
Signal is defaulted as 0, and chip row control module controls GOA circuit sweeps odd rows at this time, at the same time data buffer area
Export the viewdata signal of odd rows to data-driven module, extremely by data-driven module outputting drive voltage signal
Odd rows.
When the scanning of the first row of odd rows, OE_Count is started counting, when OE_Count count value is n, Y
=1, while image data demodulation module solution is transferred to and accords with Gn row with HE end mark, so that OE_SYNC output valve becomes 1.This
When or door EN output valve be 1, at this time chip row control module control GOA circuit sweeps even number line sub-pixel, count at the same time
According to the viewdata signal of buffer area output even number line sub-pixel to data-driven module.
When OE_Count count value is 2n, frame image frame display is completed；This hour counter Y output valve is 0.When aobvious
When showing that driving chip receives next frame image data again, OE_Count is reset count value using frame synchronizing signal VSYNC
(RESET), while image data demodulation module is using frame synchronizing signal VSYNC that OE_SYNC output valve is become 0.
Wherein, the control odd rows and idol that the chip row control module in display driver chip receives or door exports
The enable signal (EN) of several rows of sub-pixels output, as EN=0, chip row control module controls GOA circuit sweeps odd-numbered line
Pixel；As EN=1, chip row control module controls GOA circuit sweeps even number line sub-pixel, wherein and 1 is high level signal, 0
For low level signal.Or the input signal of door is Y and OE_SYNC, Y-signal is the output signal of counter OE_Count；OE_
SYNC is the output signal of image data demodulation module, when image data demodulation module solution is transferred to the figure with HE end mark symbol
As exporting OE_SYNC signal after data.VSYNC is a synchronization signal when frame starts, and when a frame starts, i.e. VSYNC is 1
When, OE_SYNC default value is 0, completes G2n-1OE_SYNC value is 1 after row demodulation, becomes 1 from next frame VSYNC synchronization signal
When, the value of OE_SYNC becomes 0.
The input signal of counter is row synchronizing clock signals HYSYN, is opened when display driver chip scans the first row G1
Begin to count, when Accounting Line Number mesh reaches n (total line number that 2n is a frame image), Y-signal output 1；When Accounting Line Number mesh reaches
When 2n, Y-signal output 0 completes the statistics of a frame data row, next frame VSYNC synchronization signal resets count value at this time
(RESET)。
As shown in figure 11, the driving voltage letter within the display time of a frame image frame, on the odd rows
Number polarity is identical, and the drive voltage signal polarity on the even number line sub-pixel is identical, and the drive on the first kind sub-pixel
Dynamic voltage signal is opposite with the drive voltage signal polarity on the second class sub-pixel.It can reduce the power consumption of mobile terminal.
By or door count pick up device output Y-signal and image data demodulation module output OE_SYNC signal come
Control switching, can be improved the reliability to first kind sub-pixel and the second class sub-pixel switched scan.
