The technical solution of offer can reduce the power consumption of display device when showing pure color picture.
In the embodiment of the present invention, the pixel in array substrate be can be comprising red sub-pixel, green sub-pixels and blue
The three-color pixel of sub-pixel, as shown in Figure 1, being also possible to also other multiple sub- pictures comprising white sub-pixels, yellow sub-pixel
Element.In addition, the sub-pixel colors of same row can be the same or different, and such as: when array substrate includes M row, in same row
It is red sub-pixel that preceding i row, which is blue subpixels, remaining rows, and wherein i is the positive integer less than M.
In the embodiment of the present invention, if the sub-pixel quantity of every a line is 2N, each grid line and N number of (odd bits or idol
Numerical digit) sub-pixel connection, the quantity of data line is also N item, and every data line connect (side and odd number with the sub-pixel of its two sides
The sub-pixel of the sub-pixel connection of position, the other side and even bit connects).Gated sweep letter is provided to a grid line in driving circuit
Number when, driving circuit inputs corresponding driving signal to N data line, so that N number of sub-pixel connect with the grid line respectively must
To corresponding driving signal.
It should be noted that the color and second driving signal pair of the corresponding each sub-pixel of above-mentioned first driving signal
The color for each sub-pixel answered is identical to be meant that: data line x receives the first driving signal and is supplied to the first sub-pixel, receives the
Two driving signal is supplied to the second sub-pixel, and the color of the first sub-pixel is identical as the color of the second sub-pixel, and data line x is battle array
Any bar data line in column substrate.
The power consumption of driving circuit is directly proportional to driving current, and the calculation of driving current are as follows: I=CVF, wherein C is
Capacitor, the V of data line are the voltage of data line, F is switching frequency of the driving circuit to data line input drive signal.Therefore,
It can be seen that reduction driving circuit can be reached to the switching frequency of data line input drive signal by reducing driving circuit
The effect of power consumption.
When showing pure color picture, the driving signal of the sub-pixel of corresponding same color is continuously exported by driving circuit,
It can reduce switching frequency of the driving circuit to data line input drive signal, to reduce the effect of the power consumption of display device.
Further, identical positioned at the sub-pixel colors of same row.
Preceding i row is blue son when being located at the sub-pixel colors difference of same row, such as in the above-mentioned same row enumerated
Pixel, remaining rows are red sub-pixel, then preceding i row and the driving needs of remaining rows separate progress.
In the present embodiment, the sub-pixel colors positioned at same row are identical, can be convenient for the sub- picture of whole in array substrate
Element carries out unified driving, and driving method is simpler and can further decrease the power consumption of display device entirety.
