Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing pair
This utility model embodiment is described in further detail.
Fig. 1 is the structural representation of display screen in prior art.As it is shown in figure 1, in the prior art,
In one display screen, an only driving chip IC, is driven in display screen all of by this driving chip IC
Pixel works.Generally each pixel can be split as again tri-sub-pixel unit of RGB, same
Three sub-pixel unit in pixel can neighbouring arrange, if a display screen has M row pixel,
So this driving chip IC is accomplished by driving 3*M row sub-pixel unit.
The structural representation of a kind of display screen that Fig. 2 provides for this utility model embodiment.As in figure 2 it is shown,
The display screen that this utility model embodiment provides includes the driving chip of many concurrent workings, the picture of display screen
Element is divided into the block of pixels identical with driving chip quantity, and each block of pixels is driven by a driving chip.
One driving chip only drives the one part of pixel in display screen, each driving chip concurrent working, from
And decrease the total time of all pixels scanning in display screen, improve the refresh rate of screen.
In a preferred embodiment, the display screen that this utility model embodiment provides includes N concurrent working
Driving chip: the first driving chip IC_1 ..., N driving chip IC_N；Total 3*M row is sub-
Pixel cell.It is identical that the pixel of whole screen is divided into N number of size by this preferred embodiment from top to bottom
Block of pixels, all comprises 3*M/N row sub-pixel unit wherein in each block of pixels, M, N are positive integer,
N can be divided exactly by M.First driving chip IC_1 drive the sub-pixel unit ... in the first block of pixels,
N driving chip IC_N drives the sub-pixel unit in N block of pixels.Element in display screen is divided into
Equal-sized block of pixels, when using identical driving chip, the time of each block of pixels scanning is equal,
It is equilibrium that the work of every driving chip meets, and all block of pixels can complete scanning in the same time.
Fig. 3 is the sub-pixel unit of display screen and the connected mode schematic diagram of driving chip in prior art.
As it is shown on figure 3, each sub-pixel unit of display screen is generally controlled by a transistor in prior art
System, transistor one end is source electrode, inputs display data signal, and one end is grid, inputs this transistor and opens
The control signal opening or closing.A driving chip IC is the most only used to complete each sub-pixel unit
Grid and source drive.It is connected in parallel on a raster data model line with the sub-pix of string, and this string
Sub-pix source drive line be consecutively connected on driving chip IC.When display screen scans by column,
Sub-pixel unit quantity in every string is the most, and the total time of this row sub-pixel unit scanning is the longest, is subject to
It is limited to the physical factor that display screen matrix drives, it is ensured that on the premise of display effect, this time can not be the biggest
Reduce in degree.As a example by 4 pel arrays, string has 2*3 sub-pixel unit, therefore has 6
Bar source data line is connected on driving chip IC, has 2 raster data model lines simultaneously, controls two row respectively
Pixel cell scans.

Source drive line, sub-pixel unit R1_1, R2_1, G1_1, G2_1, B1_1, B2_1 divide
Being the first block of pixels, the source drive line of each sub-pixel unit is connected respectively to the first driving chip IC_1；
Sub-pixel unit R1_1, R2_1, G1_1, G2_1, B1_1, B2_1 are divided into the second block of pixels,
The source drive line of each sub-pixel unit is connected respectively to the second driving chip IC_2.In prior art, need
To be charged first row sub-pixel unit and secondary series sub-pixel unit respectively driving, at the present embodiment
In once for this two row pixel simultaneously be charged drive, thus guaranteeing display resolution and pixel charging
On the basis of time, the sweep time of display screen becomes original half, and refresh rate promotes at double.
The connected mode of display screen as a example by 4 pel arrays, this utility model provided above and work
Principle is illustrated, and this programme can expand to the display screen of arbitrary resolution.When display screen includes N
During the driving chip of concurrent working, the transistor of the sub-pixel unit of every adjacent N row from first row
Grid is connected in parallel on same raster data model line, and the two ends of this raster data model line connect this N respectively
Driving chip；In each block of pixels, the source electrode of the transistor of sub-pixel unit is consecutively connected to drive
The driving chip of this block of pixels.Once it is charged for N row pixel driving simultaneously, thus reduces each frame
Needing the columns of scanning, make shorten to original 1/N the sweep time of whole screen, refresh rate rises to
N times originally.
The each source data line of driving chip IC of the display screen that utility model embodiment provides is transmitted
Display signal there are differences with framework of the prior art, such as in Fig. 4, the first driving chip IC_1
Front two source data lines connect is R1_1 and R2_1；And in Fig. 3, before driving chip IC
Article two, that source data line connects is R1_1 and G1_1；The data order of two kinds of display frameworks is different, because of
This needs to carry out data mapping.The video data of the display screen that Fig. 5 provides for utility model embodiment maps
Relation table；Wherein, Fig. 5 (a) is to carry out the video data sequence list before data mapping；Fig. 5 (b)
For carrying out the video data sequence list after data mapping.As it is shown in figure 5, with 1920*1080 resolution
As a example by, R1_1 first digit represents the row at display pixel place, and second digit represents pixel place
OK.In Fig. 5 (b), the first half data are for the pixel of display screen half, are transmitted to the first driving
Chip IC _ 1；Later half data, for second half pixel of display screen, are transmitted to the second driving core
Sheet IC_2.After having carried out data and having mapped, use the driving chip of existing routine can realize we
Case, reduces chip development and puts into.
The display screen that this utility model provides may be used for the display of high-resolution or high refresh rate, electricity
Depending in, the product such as mobile phone, panel computer or virtual reality device.Utilize the scheme that this utility model provides,
Many driving chip, the one part of pixel of parallel drive display screen can be used.When keeping dividing of display screen
When resolution is constant, display screen sweep time is greatly shortened, thus realizes high refresh rate.When keeping display
When the refresh rate of screen is constant, within the identical time, the sub-pixel unit increasing number driven can be charged,
Thus realize high-resolution.Many driving chip can also be used to improve resolution and the brush of display screen simultaneously
New rate, principle is identical, repeats no more.
The display screen that this utility model provides is particularly suited for virtual reality device, can meet virtual simultaneously
Real world devices is to display screen high-resolution and the requirement of high refresh rate, high-resolution clearly being supplied to user
While clear picture, reduce picture delay phenomenon, it is to avoid the inadaptable sense of cause the user dizziness, improve
Consumer's Experience.
