Detailed Description

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

Example one

Referring to fig. 2, fig. 2 is a flowchart of a pixel matrix driving method according to an embodiment of the invention. The pixel matrix driving method is suitable for displays currently having pixel arrays, such as LCD displays, LED displays, OLED displays, and the like.

The pixel matrix comprises a plurality of sub-pixels which are arranged in a matrix, the polarity of a data line is inverted once every two columns, the polarity of a voltage loaded along the direction of the data line is exchanged once every N sub-pixels, and every N sub-pixels, each data line alternately loads a voltage to the sub-pixels of the I column and the I +2 column, wherein the method comprises the following steps:

step 1, receiving image data, and acquiring original pixel data according to the image data;

step 2, generating a first driving voltage and a second driving voltage according to the original pixel data;

and 3, loading the first driving voltage or the second driving voltage to the pixel matrix along a data line in one frame, wherein I is more than or equal to 1, and N is more than or equal to 2.

In the prior art, the original pixel data, that is, a specific pixel value displayed by each sub-pixel in a pixel matrix in each frame correspondingly, the pixel value input to each sub-pixel is directly determined by the image data input to the TCON without processing the original pixel data, which is affected by the polarity of the sub-pixels, and thus, the polarity of the sub-pixels is easily subjected to crosstalk, bright and dark lines and other negative effects.

In this embodiment, the original pixel data is processed to obtain further first gray scale data and second gray scale data, and the pixel gray scales of the first gray scale data and the second gray scale data are different, and then the first gray scale data and the second gray scale data are loaded onto the corresponding sub-pixels at certain arrangement intervals between different pixels or different frames.

In a specific example, the first gray scale data is regarded as high gray scale data, the second gray scale data is regarded as low gray scale data, and correspondingly, the voltage magnitude input to the sub-pixel is determined by the gray scale, and a high gray scale voltage corresponding to the high gray scale data, namely, a first driving voltage is generated; it should be noted that the low gray scale voltage corresponding to the low gray scale data, i.e. the second driving voltage, represents the relative values of the two gray scales, and the values are not limited separately.

In one embodiment, the data lines are alternately routed on the left side of the I-th column of sub-pixels and the left side of the I + 1-th column of sub-pixels, and form a zigzag routing structure. Specifically, referring to fig. 3, fig. 3 is a schematic diagram of a pixel matrix driving architecture according to an embodiment of the present invention.

Taking N as an example, the polarity of the voltage loaded along the data line direction is switched once every 2 sub-pixels, in the first column, the data line D1 is routed to the middle position between the second sub-pixel and the third sub-pixel along the data line direction from the starting end along the left side of the first sub-pixel in the first column, the data line is routed to the left side position of the second column of sub-pixels along the scanning line direction and is routed to the middle position between the fourth sub-pixel and the fifth sub-pixel along the data line direction, after the data line is routed to the left side position of the first column of sub-pixels along the scanning line direction, the data line continues to run along the data line direction, and the data line sequentially circulates, and is completely laid in a zigzag manner. In the connection, taking the data line D2 as an example, the two sub-pixels on the left side are connected to the left line, and the two sub-pixels on the right side are connected to the right line, and the connection is sequentially repeated to complete the circuit connection layout.

Two consecutive sub-pixels have the same polarity when viewed from a row, the polarity of the next two consecutive sub-pixels is opposite to that of the first two sub-pixels, the polarity of the next two consecutive sub-pixels is identical to that of the first two sub-pixels when viewed from a column, and the like, wherein the polarity of the voltage applied to the sub-pixels is inverted every two sub-pixels along the scan line direction, the polarity of the voltage applied to the sub-pixels is inverted every two sub-pixels along the data line direction, P in fig. 3 represents a positive voltage, N in fig. 3 represents a negative voltage, the polarity inversion can be represented as PPNN … PPNN or NNPP … NNPP when viewed from a column, and the polarity inversion can be represented as PNNP … PNNP or NPPN … NPPN when viewed from a row.

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

For example, if the original pixel value at the a position is 128 gray, and the a position should output a high gray, i.e. H, according to the above rule of the present invention, after calculation, in this example, H of 128 is 138 gray, 138 gray is output to the a position, the data driving unit receives 138 gray, and according to the predetermined conversion rule, the voltage corresponding to 138 gray is 10V, and finally the voltage signal of 10V is output to the a position. Generally, the high-low gray scale adjustment range is determined according to the material of the liquid crystal or the like.

For example, if the original pixel value at the B position is 128 gray, and the B position should output a low gray, i.e., L, according to the above rule of the present invention, the calculation is performed, in this example, if L of 128 is 118 gray, 118 gray is output to the B position, the data driving unit receives 118 gray, and according to the predetermined conversion rule, the voltage corresponding to 118 gray is 8V, and finally the voltage signal of 8V is output to the B position.

Referring to the following example, please refer to fig. 4, wherein fig. 4 is a schematic view illustrating gray scale loading of a pixel matrix according to an embodiment of the present invention. When viewed from a row, the gray scale voltages loaded to the sub-pixels are alternated, when viewed from a column, the gray scale voltages loaded to the sub-pixels are alternated, and so on, where H in fig. 4 represents a high gray scale voltage, L represents a low gray scale voltage, when viewed from a column, the gray scale transitions can be represented as HLHL … HLHL or LHLH … LHLH, and when viewed from a row, the gray scale transitions can be represented as HLHL … HLHL or LHLH … LHLH.

For the conventional driving structure in the prior art, a 2-Line inversion data Line driving method is needed to improve the crosstalk problem, so the design of the conventional driving structure with 2-Line inversion to realize an 8-Domain H/L structure will consume the power of the panel, and the cost of the power circuit board and the temperature of the driving IC will be increased accordingly.

Alternatively, in a specific embodiment, generating the first driving voltage and the second driving voltage according to the original pixel data includes:

In one implementation, the present embodiment generates the driving signals for driving the sub-pixels by using two different sets of gammas (gammas) to generate the driving signals for driving the sub-pixels, so that the set of original data driving signals generate two sets of driving voltages under the action of different gammas, thereby implementing the driving control of the present invention. In a specific implementation of the embodiment, Tcon outputs a set of gray scales, and the data driving circuit generates two sets of gammas, each set driving different sub-pixels respectively, so as to achieve the same technical effect as the foregoing embodiment.
