Description
Technical Field
The present invention relates to the field of display panels, and in particular, to a dual-driving architecture of a display panel and a switching method thereof.
Background
In a liquid crystal display device, a driving voltage applied to liquid crystal molecules must be inverted at intervals to avoid permanent damage caused by polarization of a liquid crystal material and to avoid image sticking effects. Accordingly, various polarity inversion methods have been proposed, including: frame inversion, row inversion, column inversion, and dot inversion. The frame inversion, the row inversion and the column inversion are caused by the large-area same polarity, and when the VCOM voltage is shifted, the positive polarity and the negative polarity are asymmetric. Obvious jitter can occur in the picture. Dot inversion can well solve flicker, but can lead to a sharp increase in screen.
The current LCD display architecture is mainly divided into a Strip architecture and a FLIP architecture. The Strip architecture is that sub pixels with the same color in the same column are used for transmitting pixel information as one data line, and under the architecture, column overturning can enable the column pixels to seriously pull VCOM of the column, so that a picture is easy to flash on cotton lines, and obvious phenomena such as cross talk and the like occur. The FLIP architecture can realize point turnover by column turnover, and can solve the problems of picture flickering and power consumption at the same time, but the current large-size high-refresh display is faced, and bright and dark lines appear on the picture due to insufficient charging.
Thus, the panel Strip and FLIP drive architectures each have advantages and disadvantages, and the two drive mechanisms combine to achieve complementation.

A storage capacitor Cst, which may be used to store a data voltage for the sub-pixel 11 to emit light, a pixel capacitor Clc (omitted in fig. 1), and the like may also be included in the present specific pixel circuit. In other embodiments, other complex circuit structures may be included in the pixel circuit, which are not limited herein. The three primary color sub-pixels in the pixel unit 10 may be arranged along a row direction or a column direction, that is, R, G, B may be arranged along a row direction or a column direction, which is not limited herein. Each sub-pixel is connected with an independent scanning line and a data line so as to charge different data voltages, and color (gray scale) display is realized.
In the first driving architecture, the sub-pixels of each row are turned on by the same scan line G, and the sub-pixels of each column are driven by the same data line D. The architecture is driven in a column inversion mode, that is, in the current frame, the data of the same column of sub-pixels are all of the same polarity, and the next frame is converted into another polarity. In the first driving architecture, when the common electrode voltage is shifted, the positive and negative voltages of the sub-pixels in the column are asymmetric, so that the brightness is different and flicker occurs.
Fig. 3 is a schematic structural diagram of an embodiment of a second driving architecture of the present application. The second driving architecture includes a plurality of pixel units 10 arranged in an array, and scan lines G arranged in a row direction and data lines D arranged in a column direction. As shown in fig. 3, the odd-numbered row scan line G is connected to the odd-numbered row pixel unit 10, the even-numbered row scan line G is connected to the even-numbered row pixel unit 10, the odd-numbered column data line D is connected to the odd-numbered row pixel unit 10 of the current odd-numbered column and to the even-numbered row pixel unit 10 of the previous column, and the even-numbered column data line D is connected to the odd-numbered row pixel unit 10 of the current even-numbered column and to the even-numbered row pixel unit 10 of the previous column, thereby forming a second driving architecture. In the second driving architecture, the odd-numbered line scanning line G transmits a scanning signal to the pixel units 10 of the odd-numbered line, the even-numbered line scanning line G transmits a scanning signal to the pixel units 10 of the even-numbered line, the odd-numbered line data line D transmits a data signal to the pixel units 10 of the odd-numbered line of the current odd-numbered column and the even-numbered line of the previous column, and the even-numbered line data line D transmits a data signal to the pixel units 10 of the odd-numbered line of the current even-numbered column and the even-numbered line of the previous column, thereby forming a zigzag second driving architecture. In another embodiment, the odd column data lines are connected to the even row pixel units 10 of the odd columns and the even column odd row pixel units 10, the even column data lines are connected to the even column pixel units 10 of the even columns and to the odd column pixel units 10 of the odd columns, that is, the pixel units of the same column are connected to the data lines D (the even column and the odd column data lines) of two adjacent columns in a staggered manner, and in particular, the connection manner can be further referred to fig. 4, and fig. 4 is a schematic structural diagram of another embodiment of the second driving architecture of the present application.
In the second driving architecture, taking the second column data line D2 as an example, the second column data line D2 of the first row charges the sub-pixels of the second column, and the data line D2 of the second row and the second column becomes to charge the sub-pixels of the first column. In the column inversion driving mode, a single data line of the current frame transmits the same polarity voltage, and adjacent sub-pixels in the same column have opposite polarities, so that column inversion driving is realized, and sub-pixel point inversion is realized. In this driving architecture, however, the pixels have a charging difference from bright to bright and from black to bright, so that a brightness difference occurs, and thus a phenomenon of a lateral bright and dark line occurs.
Thus, there are advantages and disadvantages to each of the separate first and second drive architectures.
