Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the display substrate, the driving method thereof, and the display device in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a display substrate according to an embodiment of the present invention, as shown in fig. 1, the display substrate includes: the substrate and a plurality of common electrode patterns 1, a plurality of first compensation units 2 and a plurality of second compensation units 3 located above the substrate, each common electrode pattern 1 is connected to a corresponding common electrode signal line Lcom, the first compensation units 2 corresponding to the common electrode patterns 1 are connected to the corresponding common electrode signal line Lcom and the first compensation signal line LA, and the second compensation units 3 corresponding to the common electrode patterns 1 are connected to the corresponding common electrode signal line Lcom and the second compensation signal line LB. The first compensation unit 2 is used for pulling up the common voltage to the reference voltage under the control of the first compensation voltage output by the first compensation signal line LA when the common voltage output by the common electrode signal line Lcom is lower than the reference voltage; the second compensation unit 3 is used for pulling down the common voltage to the reference voltage under the control of the second compensation voltage output by the second compensation signal line LB when the common voltage output by the common electrode signal line Lcom is higher than the reference voltage.
Wherein the base substrate is not shown in the figure.
Fig. 2 is an operation schematic diagram of the first compensation unit and the second compensation unit in fig. 1, and fig. 3 is another operation schematic diagram of the first compensation unit and the second compensation unit in fig. 1, and as shown in fig. 1, fig. 2 and fig. 3, the first compensation unit 2 includes a first switch T1, a control pole of the first switch T1 is connected to the first compensation signal line LA, a first pole of the first switch T1 is connected to the first compensation signal line LA, and a second pole of the first switch T1 is connected to the corresponding common electrode signal line Lcom; the second compensation unit 3 includes a second switch T2, a control pole of the second switch T2 is connected to the corresponding common electrode signal line Lcom, a first pole of the second switch T2 is connected to the second compensation signal line LB, and a second pole of the second switch T2 is connected to the corresponding common electrode signal line Lcom. In this embodiment, the first switch transistor T1 is a TFT, and the second switch transistor T2 is a TFT.
Fig. 4 is a timing diagram of signals of the display substrate of fig. 1, as shown in fig. 4, the first compensation voltage VA is higher than the reference voltage Vcom, and the second compensation voltage VB is lower than the reference voltage Vcom. Preferably, the difference between the first compensation voltage VA and the reference voltage Vcom is equal to the difference between the reference voltage Vcom and the second compensation voltage VB, and the formula of the difference is: VdeltaA is a difference between the first compensation voltage VA and the reference voltage Vcom, and VdeltaB is a difference between the reference voltage Vcom and the second compensation voltage VB. For example: when VdeltaA is 10V, VA is 5V, VB is-5V, and Vcom is 0V. VdeltaA is proportional to the width-to-length ratio of the first switching tube T1, and VdeltaB is proportional to the width-to-length ratio of the second switching tube T2, so that the current of the first switching tube T1 is proportional to the width-to-length ratio of the first switching tube T1, and the current of the second switching tube T2 is proportional to the width-to-length ratio of the second switching tube T2. In this embodiment, the current of the first switch transistor T1 and the current of the second switch transistor T2 during operation and stop are controlled by setting the width-to-length ratio of the first switch transistor T1 and the width-to-length ratio of the second switch transistor T2, so as to achieve the purpose of rapidly compensating and reducing the leakage current during operation stop, thereby reducing the power consumption.
In this embodiment, the first compensation voltage VA is adjusted according to the reference voltage Vcom, and the second compensation voltage VB is adjusted according to the reference voltage Vcom. Specifically, the difference between the first compensation voltage VA and the reference voltage Vcom is preset, and the difference between the reference voltage Vcom and the second compensation voltage VB is preset, so that the difference between the first compensation voltage VA and the reference voltage Vcom and the difference between the reference voltage Vcom and the second compensation voltage VB are fixed and unchangeable, and at this time, when the reference voltage Vcom changes, the first compensation voltage VA and the second compensation voltage VB are also adjusted according to the reference voltage Vcom, so as to ensure that the difference between the first compensation voltage VA and the reference voltage Vcom and the difference between the second compensation voltage VB are unchangeable. Thereby enabling each small-sized product to independently set the reference voltage Vcom and still operate normally under the condition of independently setting the reference voltage Vcom.
The working process of the display stage of the display substrate of the present embodiment is described in detail with reference to fig. 2, 3 and 4.
In this embodiment, a difference VdeltaA between the first compensation voltage VA and the reference voltage Vcom is equal to a threshold voltage of the first switch transistor T1, and a difference VdeltaB between the reference voltage Vcom and the second compensation voltage VB is equal to a threshold voltage of the second switch transistor T2.
As shown in fig. 2 and 4, when the common voltage output by the common electrode signal line Lcom is lower than the reference voltage Vcom, the difference between the first compensation voltage VA and the common voltage output by the common electrode signal line Lcom is greater than the threshold voltage of the first switch T1, the first switch T1 is turned on under the control of the first compensation voltage VA output by the first compensation signal line LA, and the first current flows from the first compensation signal line LA to the common electrode signal line Lcom through the first switch T1. Since the common voltage output by the common electrode signal line Lcom is lower than the reference voltage Vcom, and the difference between the common voltage output by the common electrode signal line Lcom and the second compensation voltage VB is smaller than the threshold voltage of the second switch tube T2, the second switch tube T2 is turned off, and no current flows from the common electrode signal line Lcom to the second compensation signal line LB. The first current flows into the common electrode signal line Lcom to pull up the common voltage to the reference voltage Vcom.
As shown in fig. 3 and 4, when the common voltage output by the common electrode signal line Lcom is higher than the reference voltage, and the difference between the first compensation voltage VA and the common voltage output by the common electrode signal line Lcom is smaller than the threshold voltage of the first switch transistor T1, the first switch transistor T1 is turned off, and no current flows from the first compensation signal line LA to the common electrode signal line Lcom. Since the common voltage output by the common electrode signal line Lcom is higher than the reference voltage Vcom, the difference between the common voltage output by the common electrode signal line Lcom and the second compensation voltage VB is greater than the threshold voltage of the second switch T2, the second switch T2 is turned on under the control of the common voltage output by the common electrode signal line Lcom, and then the second current flows from the common electrode signal line Lcom to the second compensation signal line LB through the second switch T2. A second current flows from the common electrode signal line Lcom to pull down the common voltage to the reference voltage Vcom.
The common electrode signal line Lcom outputs a compensation current through the second switch transistor T2 to pull down the common voltage to the reference voltage Vcom.
Fig. 5 is a schematic diagram of the compensation process of the first compensation unit and the second compensation unit in fig. 3, and as shown in fig. 5, a curve (dotted line) for pulling down the common voltage to the reference voltage Vcom in the present embodiment and a curve (solid line) for pulling down the common voltage to the reference voltage Vcom in the prior art are obtained through experiments.
In this embodiment, the common electrode signal line Lcom outputs the common voltage pulled up to the reference voltage Vcom or pulled down to the reference voltage Vcom to the corresponding common electrode pattern.
