DRIVING METHOD FOR PIXEL MATRIX AND DISPLAY DEVICE

FIELD OF THE DISCLOSURE

The present invention belongs to the field of image display technologies, and more particularly to a driving method and a driving device for a pixel matrix and a display device.

BACKGROUND

VA type liquid crystal panels are relatively widely used in current display products. At present, the VA type panels are mainly divided into two types, one is the MVA (Multi-domain Vertical Alignment) type, and the other is the PVA (Patterned Vertical Alignment) type.

The principle of an MVA technology is to add protrusions to form multiple visible areas. The liquid crystal molecules are not completely vertically arranged in a static state, and the liquid crystal molecules are horizontally arranged after a voltage is loaded, so that the light can pass through respective layers. The PVA is an image vertical adjustment technology that directly changes the structure of a liquid crystal cell, so that the display performance can be greatly improved to acquire the brightness output and contrast superior to the MVA.

However, the above manner of the prior art improves the Washout problem to a certain extent, but the temperature raise of a driving chip caused by a relatively large power consumption of the panel is caused, which leads to the increase in a manufacturing cost and a poor user experience.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will be further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

First Embodiment

Referring to FIG. 2, FIG. 2 is a flowchart of a driving method for a pixel matrix according to a first embodiment of the present invention. The driving method for a pixel matrix is applicable to the displays currently having a pixel array, such as an LCD display, an LED display and an OLED display.

The pixel matrix includes a plurality of sub-pixels arranged in a matrix, the polarity of data lines is inverted once every two columns, the polarity of the voltage loaded in the direction of the data lines is exchanged once every N sub-pixels, and each data line alternately loads the voltage to the lth column and (l+2)th column of sub-pixels every N sub-pixels. The driving method includes: step S1: receiving image data, and acquiring original pixel data according to the image data; S2: generating a first driving voltage and a second driving voltage according to the original pixel data; and S3: loading the first driving voltage or the second driving voltage to the pixel matrix along the data lines within one frame, wherein l≥1, N≥2.

The image data refers to a digital signal input to a timing controller (TCON). The image data is input frame by frame, and the original pixel data is acquired by parsing the image data. In an existing technology, the original pixel data is a specific pixel value correspondingly displayed by each sub-pixel in the pixel matrix within each frame, the pixel value input to each sub-pixel is directly determined by the image data input into the TCON, and the original pixel data is not processed. Such a manner is affected by the polarity of the sub-pixels, and the polarity of the sub-pixel is caused to easily generate crosstalk, bright and dark lines and other negative effects.

In a specific embodiment, generating a first driving voltage and a second driving voltage according to the original pixel data includes acquiring first gray scale data and second gray scale data according to the original pixel data; and generating, according to the first gray scale data and the second gray scale data, the first driving voltage corresponding to the first gray scale data, and the second driving voltage corresponding to the second gray scale data.

In the present embodiment, by processing the original pixel data, the further first gray scale data and second gray scale data are acquired. The pixel gray scales of the first gray scale data and the second gray scale data are enabled to be different, so that the gray scales are loaded to the corresponding sub-pixels among different pixels or different frames according to a certain arrangement interval. The solution in the present embodiment can generate two groups of different gray scales corresponding to different sub-pixels respectively. In such manner, the influence on the voltage loaded to the sub-pixels caused by the polarity reversal is avoided, thereby avoiding the occurrence of crosstalk and bright dark lines.

In a specific example, the first gray scale data is, for example, high gray scale data, and the second gray scale data is, for example, low gray scale data. Correspondingly, the size of the voltage input to the sub-pixels is determined by the gray scale, so as to generate a high gray scale voltage corresponding to the high gray scale voltage, that is, the first driving voltage, and a low gray scale voltage corresponding to the low gray scale data, that is, the second driving voltage. It is mentionable that that the above high gray scale and low gray scale represent the relative values of two groups of gray scales rather than limiting the values thereof separately.

In a specific embodiment, the data lines are alternately routed on the left side of the lth column of sub-pixels and the left side of the (l+1)th column of sub-pixels, and form a bow-shaped routing structure. Specifically, referring to FIG. 3, FIG. 3 is a schematic diagram of a driving architecture for a pixel matrix according to an embodiment of the present invention.

By taking N=2 as an example, the polarity of the voltage loaded in the direction of the data lines (or the length direction of the data lines, for example, the column direction in FIG. 3) is exchanged once every 2 sub-pixels. In the first column, the data line D1 is routed from the initial end in the direction of the data lines along the left side of the first sub-pixel of the first column to the middle position between the second sub-pixel and the third sub-pixel, and the data line is routed to the left side of the second column of sub-pixels in the direction of the scan lines, and routed to the middle position between the fourth sub-pixel and the fifth sub-pixel in the direction of the data lines. The data line is routed in the direction opposite to the scan lines to the left side position of the first column of sub-pixels, and is then continuously routed in the direction of the data lines, and so on till the bow-shaped routing layout is completed. During the connection, the data line D2 is taken as an example, the line close to the left side is connected to the two sub-pixels on the left side, the line close to the right side is connected to the two sub-pixels on the right side, and so on till the circuit connection layout is completed.

Viewed from a certain row, the two consecutive sub-pixels have the same polarity, and the next two consecutive sub-pixels have the polarity opposite to the above two polarities. Viewed from a certain column, the two consecutive sub-pixels have the same polarity, and the next two consecutive pixels have the polarity opposite to the above two sub-pixels, and so on. As a whole, the polarity of the voltage loaded to the sub-pixels is inverted once every two sub-pixels in the direction of the scan lines, and the polarity of the voltage loaded to the sub-pixels is inverted once every two sub-pixels in the column direction. In FIG. 3, P represents a positive voltage and N represents a negative voltage. Viewed from a certain column, the polarity reversal can be expressed as PPNN . . . PPNN or NNPP . . . NNPP, and viewed from a certain row, the polarity reversal can be expressed as PNNP . . . PNNP or NPPN . . . NPPN.

After the gray scale to be displayed by each pixel position is determined according to the rule of the present invention, the timing controller correspondingly adjusts the original gray scale of the pixel position to a high gray scale or a low gray scale, and sends the adjusted gray scale value to a data driving unit. The data driving unit outputs a corresponding voltage according to the gray scale value.

For example, the original pixel value of the A position is 128 gray scale. According to the above rule of the present invention, a high gray scale, that is, H should be output to the A position. After calculation, in such example, the H of 128 equals to the 138 gray scale value, and then the 138 gray scale is output to the A position. The data driving unit receives the 138 gray scale, according to the predetermined conversion rule, the voltage corresponding to the 138 gray scale is 10V, and finally the voltage signal of 10 V is output to the A position. Generally, the adjustment range of the high and low gray scales is determined by the difference of materials such as liquid crystal.

For another example, the original pixel value of the B position is 128 gray scale. According to the above rule of the present invention, a low gray scale, that is, L should be output to the B position. After calculation, in such example, the L of 128 equals to the 118 gray scale value, and then the 118 gray scale is output to the B position. The data driving unit receives the 118 gray scale, according to the predetermined conversion rule, the voltage corresponding to the 118 gray scale is 8V, and finally the voltage signal of 8V is output to the B position.

Referring to the following example and referring to FIG. 4, FIG. 4 is a schematic diagram of gray scale loading of a pixel matrix according to an embodiment of the present invention. Viewed from a certain row, the gray scale voltage loaded into the sub-pixels is alternately converted, and viewed from a certain column, the gray scale voltage loaded to the sub-pixels is alternately converted, and so on. In FIG. 4, H represents the high gray scale voltage, and L represents the low gray scale voltage. Viewed from a certain column, the gray scale conversion can be expressed as HLHL . . . HLHL or LHLH . . . LHLH, and viewed from a certain row, the gray scale conversion can be expressed as HLHL . . . HLHL or LHLH . . . LHLH.

In the conventional driving architecture of the prior art, a 2-line inverted data line driving method is needed to improve the crosstalk problem. Herein, the design of achieving the 8-Domain H/L architecture by matching the conventional driving architecture with the 2-Line inversion will increase the power consumption of the panel, and the increase in power consumption will cause the temperature raise of the driver IC.

Or, in a specific embodiment, generating a first driving voltage and a second driving voltage according to the original pixel data includes: acquiring an original data driving signal of each pixel position according to the original pixel data; and acquiring the first driving voltage and the second driving voltage according to the original data driving signal.

In the method, according to the embodiment, the original pixel data corresponds to a group of gray scale values, in the data driving circuit, the original data driving signal corresponding to the gray scale value is generated, and the original data driving signal is adjusted to two different driving voltages, that is, the first driving voltage or the second driving voltage for corresponding output. In an embodiment, the present embodiment generates the driving signal for driving the sub-pixels by using two groups of different gammas. One group of original data drive signals generates two groups of driving voltages under the action of different gammas, thereby further implementing the driving control of the present invention. In specific implementation of the solution of the embodiment, the TCON outputs a group of gray scales, the data driving circuit generates two groups of gammas, and each group respectively correspondingly drives different sub-pixels, thereby achieving the same technical effect as the above embodiment.

In summary, according to the driving method for a pixel matrix of the embodiment, by using a new driving architecture and reasonably matching the high gray scale voltage and the low gray scale voltage, the pixels in the pixel matrix are not affected by the polarity. The problems such as crosstalk and bright and dark lines are avoided, and meanwhile the power consumption of the panel is reduced, the temperature of the driver IC is reduced, the cost is reduced, and the user experience is improved.

Fifth Embodiment

Referring to FIG. 10, FIG. 10 is a flowchart of a driving method for a low-color shift pixel matrix according to a fifth embodiment of the present invention. The driving architecture of the present embodiment includes a plurality of data line pairs formed by a plurality of two adjacent data lines. Two sub-pixels are disposed on the inner side of each pair of data lines, and a voltage is loaded to one corresponding sub-pixel on the inner side. Within one frame and in the direction of the data lines, the voltage is alternately loaded to the sub-pixels in a first driving manner or a second driving manner according to a first predetermined interval. In the direction of scan lines, the voltage is alternately loaded to the sub-pixels in the first driving manner or the second driving manner according to a second predetermined interval.

According to the above, the original pixel data is the specific pixel value correspondingly displayed by each sub-pixel in the pixel matrix within each frame, the pixel value input to each sub-pixel is directly determined by the image data input into the TCON, and the original pixel data is not processed. Such a manner is affected by the polarity of the sub-pixels, and the polarity of the sub-pixel is caused to easily generate crosstalk, bright and dark lines and other negative effects.

According to the driving method for a low-color shift pixel matrix of the present embodiment, a plurality of data line pairs are formed by a plurality of two adjacent data lines, two sub-pixels are disposed on the inner side of each pair of data lines, and the voltage is loaded to one corresponding sub-pixel on the inner side. Therefore, the 8-Domain low-color shift display effect is realized without increasing the additional power consumption of the panel.

For the driving architecture of the present embodiment, referring to FIG. 11, FIG. 11 is a schematic diagram of a driving architecture for a low color-shift pixel matrix according to an embodiment, which is exemplified by 8×12, that is, there are 8 rows and 12 columns of sub-pixels. For more convenient description, each sub-pixel is marked, the sub-pixel of the Nth row and the Mth column is marked as Anm, and the sub-pixel of the first row and the first column is marked as A11.

The data lines D1 and D2 are one data line pair, the data lines D3 and D4 are one data line pair, and so on.

Two sub-pixels are disposed between D1 and D2, D1 is connected to the sub-pixel A11, and D2 is connected to the sub-pixel A12. In such manner, the voltage is loaded to the sub-pixels in the first driving manner, and each data line in the data line pair loads the voltage to the adjacent sub-pixels on the inner side of such data line.

Two sub-pixels are disposed between D3 and D4, D3 is connected to the sub-pixel A14 and D4 is connected to the sub-pixel A13. In such manner, the voltage is loaded to the sub-pixels in the second driving manner, and each of the data line pairs loads the voltage to the non-adjacent sub-pixels on the inner side of such data line.

According to the above rule, within one frame, the voltage is loaded to the sub-pixels alternately in the first driving manner or the second driving manner every two sub-pixels in the direction of the data lines according to the embodiment, that is, at the first moment and the second moment, the voltage is loaded to the sub-pixels in the first driving manner, at the third moment and the fourth moment, the voltage is loaded to the sub-pixels in the second driving manner, at the fifth moment and the sixth moment, the voltage is loaded to the sub-pixels in the first driving manner, at the seventh moment and the eighth moment, the voltage is loaded to the sub-pixels in the second driving manner and so on. In the present embodiment, the first predetermined interval is every other two sub-pixels.

In the present embodiment, the voltage is loaded to the sub-pixels alternately in the first driving manner or the second driving manner every two sub-pixels in the direction of the scan lines, that is, at the same moment, D1 and D2 load the voltage to the sub-pixels in the first driving manner, D3 and D4 load the voltage to the sub-pixels in the second driving manner, D5 and D6 load the voltage to the sub-pixels in the first driving manner, D7 and D8 load the voltage to the sub-pixels in the second driving manner, and so on. In the present embodiment, the second predetermined interval is every other two sub-pixels. In the data line pair, the adjacent data line pairs alternately load in the first driving manner and the second driving manner.

For the present embodiment, the polarities of two adjacent data lines are also alternately changed. Within one frame, the data line D1 is loaded with the positive polarity voltage, the data line D2 is loaded with the negative polarity voltage, the data line D3 is loaded with the positive polarity voltage, the data line D4 is loaded with the negative polarity voltage, and so on. In the direction of the data lines, the polarity of the data lines is constant within one frame, but for the driving architecture of the present invention, the polarity of the voltage loaded to the sub-pixels of each column is inverted once every two sub-pixels, thereby achieving 2-Line inversion. The polarity of the sub-pixels of each column is in the two-positive and two-negative cycle.

Similarly, in the direction of the scan lines, the polarity of the data lines is column inversion within one frame, but for the driving architecture of the embodiment, the polarity of the voltage loaded to the sub-pixels of each row is inverted once every two sub-pixels, thus achieving 2-Line inversion, and the polarity of the sub-pixels of each row is in two-positive and two-negative cycle.

In one embodiment, loading the voltage to the sub-pixels in the first driving manner includes: generating the first driving voltage and the second driving voltage according to the original pixel data, including: acquiring first gray scale data and second gray scale data according to the original pixel data; and generating, according to the first gray scale data and the second gray scale data, the first driving voltage corresponding to the first gray scale data, and the second driving voltage corresponding to the second gray scale data.

In a specific embodiment, acquiring first gray scale data and second gray scale data according to the original pixel data includes: acquiring an original pixel value of each pixel position according to the original pixel data, and converting the original pixel value of each pixel position to the first gray scale data or the second gray scale data according to a predetermined conversion manner.

According to the above, in the present embodiment, by processing the original pixel data, the further first gray scale data and second gray scale data are acquired. The pixel gray scales of the first gray scale data and the second gray scale data are enabled to be different, so that the gray scales are loaded to the corresponding sub-pixels among different pixels or different frames according to a certain arrangement interval. The solution in the present embodiment can generate two groups of different gray scales corresponding to different sub-pixels respectively. In such manner, the influence on the voltage loaded to the sub-pixels caused by the polarity reversal is avoided, thereby avoiding the occurrence of crosstalk and bright dark lines.

After the gray scale to be displayed by each pixel position is determined according to the rule of the present invention, the timing controller correspondingly adjusts the original gray scale of the pixel position to a high gray scale or a low gray scale, and sends the adjusted gray scale value to the data driving unit. The data driving unit outputs a corresponding voltage according to the gray scale value.

For example, the original pixel value of the A position is 128 gray scale. According to the above rule of the present invention, a high gray scale, that is, H should be output to the A position. After calculation, in such example, the H of 128 equals to the 138 gray scale value, and then the 138 gray scale is output to the A position. The data driving unit receives the 138 gray scale, according to the predetermined conversion rule, the voltage corresponding to the 138 gray scale is 10 V, and finally the voltage signal of 10V is output to the A position. Generally, the adjustment range of the high and low gray scales is determined by the difference of materials such as liquid crystal.
