Description

Technical Field

[0001] The present invention relates to the technical field of electronic paper, and in particular to an anti-crosstalk electronic paper panel and electronic paper. Background Art

[0002] Crosstalk is a common problem that affects the display quality of electronic paper products. In the pixel design of conventional electronic paper panels, each pixel contains a gate line and a data line. The gate line is responsible for turning on the transistor row by row, and the data line is responsible for writing the signal into the pixel during the gate opening time. When the electronic paper product displays black, the data is generally given a positive voltage; when it displays white, the data is generally given a negative voltage. The data line of the same column of pixels is the same. A data line is arranged on the left and right sides of each column of pixels, one of which is used to provide voltage to the pixels in this column, and the other is used to provide voltage to the pixels in the adjacent column. Crosstalk often occurs when the voltage of the pixel is inconsistent with the voltage of the data transmission on both sides of it. The voltage signal on the data line will interfere with the voltage of the pixel, forming a crosstalk phenomenon.

[0003] In a certain electronic paper pixel display situation, the pixels on the left and right columns of a certain data line display different colors respectively, that is, the data line is located just on the boundary line of different color display areas of the electronic paper. For example, the pixels on the left column of the data line display white, and the pixels on the right column display black. Then, whether the data line controls the display of the left column pixels (data line transmits negative voltage) or the right column pixels (data line transmits voltage), it will interfere with the voltage of the other column of pixels, causing crosstalk of the other column of pixels. How to improve the crosstalk phenomenon that is easy to occur on the boundary line of different color display areas is an urgent problem to be solved. Summary of the invention

[0004] The present invention provides an anti-crosstalk electronic paper panel and electronic paper, so as to solve the technical problem that crosstalk phenomenon is easy to occur on the boundary line of different color display areas in the prior art.

[0007] As a preferred solution, if the first side is the left side, the second side is the right side; if the first side is the right side, the second side is the left side.

[0008] As a preferred solution, a second scanning line for controlling the switching state of pixels is provided between any adjacent pixel rows;

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figure 1 , is a schematic structural diagram of an anti-crosstalk electronic paper panel provided by an embodiment of the present invention, comprising: a plurality of pixels arranged in a matrix; a first scanning line for controlling the display state of the pixels is provided between any adjacent pixel columns;

[0026] For each pixel column, pixels in odd-numbered rows in the pixel column are connected to the first scan line on the first side of the pixel column, and pixels in even-numbered rows in the pixel column are connected to the first scan line on the second side of the pixel column; wherein the first side and the second side are opposite left and right sides.

[0027] It should be noted that there are two display states of a pixel, one is displaying black, and the other is displaying white. The first scan line is used to control whether the pixel displays black or white.

[0028] Figure 1 The electronic paper panel shown includes 12 pixels, which form 4 pixel rows and 3 pixel columns. A first scan line is provided between any adjacent pixel columns, and a first scan line can also be provided outside the outermost pixel column to ensure that the number of pixel columns is the same as the number of first scan lines, and each pixel is controlled by a first scan line.

[0029] For each pixel column, pixels in odd-numbered rows are connected to the first scan line on the first side, and pixels in even-numbered rows are connected to the first scan line on the second side. In other words, each first scan line can be connected to two adjacent pixel rows, and is connected to pixels in the same pixel column in alternate rows.

[0030] It is also necessary to note that please refer to Figure 2 , is a schematic diagram of an electronic paper panel display pattern, wherein areas numbered 1, 2, 3 and 4 display white, area numbered 5 displays black, and S1 and S2 are the first scan lines at the boundary between the black area and the white area.

[0031] In the prior art, all pixels in the same pixel column are connected to the same first scanning line. Figure 3 , is a schematic diagram of the structure of an existing electronic paper panel. Assume that the first scan line controls the display of pixels on its right side, that is, the pixels of each pixel column are connected to the first scan line on its left side.

[0032] Assume that the first scan line outputs a positive voltage to control the corresponding pixel to display black, and outputs a negative voltage to control the corresponding pixel to display white. Figure 2 When the pattern shown in FIG. 1 is displayed, the first scanning line S1 needs to output negative pressure, positive pressure and negative pressure in sequence, and the first scanning line S2 always outputs negative pressure. Assume that the time when the first scanning line S1 outputs positive pressure is t, and the time when the second scanning line outputs negative pressure is T. Then, the electronic paper panel of the present invention also displays the following Figure 2 When the pattern shown in FIG. 1 is used, the time for the first scanning line S1 to output positive voltage is The time for the second scanning line S2 to output negative voltage is

[0033] Each time the first scan line S1 outputs a positive voltage, it will interfere with the nearby pixels that display white. Each time the first scan line S2 outputs a negative voltage, it will interfere with the nearby pixels that display black. It can be seen that, compared with the prior art, the time for the first scan line S1 to output a positive voltage is halved, and the time for the second scan line S2 to output a negative voltage is reduced, which shortens the time for the prior art to interfere with the pixels and improves the crosstalk phenomenon.

[0037] It should be noted that there are two switching states of the pixel, one is that the pixel is turned on, and the other is that the pixel is turned off. The second scan line is used to control whether the pixel is in the on state or the off state.

[0038] A second scan line is provided between any adjacent pixel rows, and a second scan line may also be provided outside the outermost pixel row, to ensure that the number of pixel rows is the same as the number of second scan lines, and each pixel is controlled by a second scan line.

[0039] For each pixel row, all pixels are connected to the same second scanning line.

[0040] In a preferred embodiment, each of the pixels is connected to the corresponding first scan line and the second scan line via a thin film transistor.

[0041] In this embodiment, each pixel is connected to the first scan line and the second scan line via a thin film transistor.

[0042] In a preferred embodiment, for each thin film transistor, the drain of the thin film transistor is connected to the corresponding pixel, the source of the thin film transistor is connected to the corresponding first scan line, and the gate of the thin film transistor is connected to the corresponding second scan line.

[0043] In this embodiment, the thin film transistor has a drain, a source and a gate, wherein the drain is connected to the corresponding pixel, the source is connected to the first scan line to which the corresponding pixel is to be connected, and the gate is connected to the second scan line to which the corresponding pixel is to be connected.

[0044] In a preferred embodiment, the electronic paper panel includes: 120,000 pixels arranged in a matrix, and all the pixels constitute 300 pixel rows and 400 pixel columns.

[0045] In a preferred embodiment, the first scan line is a data line.
