Specific implementation mode
The present invention is described in further detail With reference to embodiment.But this should not be interpreted as to the present invention
The range of above-mentioned theme is only limitted to embodiment below, all models that the present invention is belonged to based on the technology that the content of present invention is realized
It encloses.
Embodiment one
Fig. 1 is referred to, Fig. 1 is a kind of picture element matrix display methods flow chart that the embodiment of the present invention provides, Ke Yiying
In display for various electronic equipment display screens, the picture element matrix includes multiple sub-pixels arranged in arrays, including with
Lower step：
Obtain original signal input data；
The first input data and the second input data are converted to according to the raw pixel data；
In a frame, corresponding first driving voltage of first input data or described second are loaded along data line direction
Corresponding second driving voltage of input data is to the picture element matrix；
Wherein, the sub-pixel length-width ratio is 3/4≤a：b≤4/3.
The display methods of the present invention can be applied in the display of various resolution requirements, but be mainly used in high-resolution
During rate is shown, such as the high-resolution display of 4K, 8K.For example, the resolution of 8K4K requires to be 7680 × 4320, i.e. X-direction
Resolution require to be 7680, the resolution of Y-direction requires to be 4320.
By taking traditional rgb pixel matrix as an example, Fig. 2 is referred to, Fig. 2 is existing pixel designed ratios and arranges schematic diagram, and one
The length-width ratio of a sub-pixel is 1:3, and the RGB sub-pixels that a complete pixel is arranged in order by three form, therefore,
X-direction is 7680 × 3 to reach 7680 resolution requirements, the then pixel quantity needed, is in the Y direction 4320 × 1.
For the picture element matrix of the present embodiment, Fig. 3 is referred to, Fig. 3 is that the pixel designed ratios of the present embodiment are shown with arrangement
It is intended to, the present embodiment is by the length for increasing sub-pixel and the corresponding width for reducing sub-pixel, to improve display effect, in this reality
It applies in example, the length-width ratio of a sub-pixel is 3:4, if specifically, traditional sub-pixel a length of a, width 3a, then the present embodiment
Sub-pixel a length of 1.5a, width 2a.
Since the scheme of the present embodiment changes the size of sub-pixel, it is wanted in X-direction to reach 7680 resolutions
It asks, then the pixel quantity needed is 7680 × 2, is in the Y direction 4320 × 1.5.In order to preferably realize the present embodiment, need
The corresponding type of drive for changing picture element matrix and driving framework.Therefore the present embodiment uses pixel sharing (shared pictures
Element) mode reaches the design of identical resolution, and under identical 8K4K resolutions, the X-direction pixel quantity of the present embodiment is:
7680x2, and the pixel quantity of Y-direction is:4320*1.5, the design that Y-direction shares 3 sub-pixels using 2 pixels complete this

It pushes away, is provided with a scan line G1 on the upside of R11, there is no scan line between R11 and R21, one is provided between R21 and G31 and is swept
Line G2 is retouched, does not have scan line between G31 and G41, and so on, vice versa.For framework, data line polarity is that row are anti-
Turn, because each column sub-pixel both sides are respectively connected with a data line, corresponding data line is strange in a row sub-pixel with carrying respectively
Several rows of sub-pixels and even number line sub-pixel, this ensures that the sub-pixel alternating polarity reversion of either rank, further, since every two
A scan line is just connected between row sub-pixel, therefore every scan line band carries the defeated of the scanning signal of the sub-pixel of its both sides
Enter.

Element) mode reaches the design of identical resolution, and under identical 8K4K resolutions, the X-direction pixel quantity of the present embodiment is:
7680x1.5 and the pixel quantity of Y-direction is:4320*2, the design that Y-direction shares 3 sub-pixels using 2 pixels complete this
Example scheme.In existing design, the pixel quantity of Y-direction is 4320 × 1=4320, and scan line quantity corresponds to Y
The pixel quantity in direction is 4320, and by taking scan frequency is 60Hz as an example, the charging time of corresponding each sub-pixel is
3.86us。
And in the design of the present embodiment, referring to table 2, the pixel quantity of Y-direction is 4320 × 2=8640, and according to this
The framework of embodiment, the quantity of scan line are 8640/2=4320, due to a frame total scanning time it is fixed,
Same sweep time, the prior art needs 4320 times, though the pixel quantity of Y-direction doubles, two pictures of Y-direction of arranging in pairs or groups
Element shares the design of a scanning linear, though the pixel quantity of Y-direction increases since then, the charging time of pixel can also maintain
It is identical as traditional design to enhance display effect, however, for X-direction, due to X-direction pixel quantity compared with the existing technology
Reduce 50%, the user experience is improved.
