Description

[0002] The current development trend of electronic products is to be thinner and lighter with diversified functions, which poses an increasing challenge to the design of display products. With the increasing popularity of active pen applications in display products, embedded touch technology is widely used.

[0003] In the existing driving circuit applied to touch display products, during the LHB (Long Horizontal Blank, intra-frame touch detection) period, the first node is in a floating state. Since the transistor electrically connected to the first electrode or the second electrode and the first node has leakage (especially when the driving circuit adopts a-Si (amorphous silicon) transistor, when the gate-source voltage of the a-Si transistor is 0, the leakage current is large), the potential of the first node will be lower than the potential of the first node of the normal row after the pit (that is, the touch stage ends), resulting in reduced gate driving capability after the pit and insufficient pixel charging capability, resulting in LHB horizontal stripes, and failure to display normally after the touch stage ends.

[0096] 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.

[0097] The transistors used in all embodiments of the present invention may be triodes, thin film transistors, field effect transistors or other devices with the same characteristics. In the embodiments of the present invention, to distinguish the two electrodes of the transistor except the gate, one electrode is called the first electrode and the other electrode is called the second electrode.

[0098] In actual operation, when the transistor is a thin film transistor or a field effect transistor, the first electrode may be a drain, and the second electrode may be a source; or, the gate may be a gate, the first electrode may be a source, and the second electrode may be a drain.

[0099] like Figure 1As shown, the driving circuit according to the embodiment of the present invention includes a first node control circuit 11, a second node control circuit 12, a third node control circuit 13 and an output circuit 10;

[0100] The first node control circuit 11 is electrically connected to the first node P1 and is used to control the potential of the first node P1;

[0101] The second node control circuit 12 is electrically connected to the second node P2, and is used to control the potential of the second node P2;

[0102] The third node control circuit 13 is electrically connected to the on-off control line SW, the first node P1 and the third node P3 respectively, and is used to control the connection or disconnection between the first node P1 and the third node P3 under the control of the on-off control signal provided by the on-off control line SW;

[0103] The output circuit 10 is electrically connected to the second node P2, the third node P3 and the driving signal terminal O1 respectively, and is used to control the output of the driving signal through the driving signal terminal O1 under the control of the potential of the second node P2 and the potential of the third node P3.

[0104] The present invention Figure 1 When the embodiment of the driving circuit shown is working, in the touch stage, the third node control circuit 13 controls the disconnection between the first node P1 and the third node P3 under the control of the on-off control signal, closes the leakage path of the third node P3, and can always maintain the potential of the third node P3 in the touch stage; in the display stage, the third node control circuit 13 controls the connection between the first node P1 and the third node P3 under the control of the on-off control signal, so as to perform normal display driving.

[0105] The embodiment of the present invention can avoid the problem that the high potential of the third node P3 cannot be maintained when the touch stage lasts too long, thereby causing the display to fail to function properly after the touch stage ends. The embodiment of the present invention can meet the touch time requirements of different active pen protocols, has wide applicability, and improves the competitiveness of touch display products.

[0106] The embodiment of the present invention cuts off the leakage path of P3, so that after the touch stage of the touch display product, especially the touch display product supporting the active pen, the potential of the third node can be maintained at a high voltage, so that the drive signal can be output normally. The embodiment of the present invention can solve the horizontal stripe problem in the LHB (Long Horizontal Blank, intra-frame touch detection) mode, and can be applied to mobile terminals, laptop computers and other products, but is not limited thereto.

[0107] Optionally, the third node control circuit includes a first transistor;

[0113] exist Figure 2 In at least one embodiment of the driving circuit shown, M1 can be an a-Si TFT (amorphous silicon thin film transistor). Since the a-Si TFT is in a positive bias state for a long time, its characteristic curve will shift to the right, causing the turn-on current Ion to decrease. When the ratio of the duration of the display phase to the duration of the touch phase is greater than 1, M1 will be in a positive bias state. Under long-term operation or reliability conditions, the characteristic curve of M1 may shift to the right, causing Ion to decrease, resulting in insufficient output of the driving signal. To avoid the above problems, at least one embodiment of the present invention includes two control sub-circuits through a third node control circuit to work alternately in the display phase to avoid the transistor included in the control sub-circuit being in a positive bias state for a long time.

[0117] In a preferred case, two on-off control lines can be used, and the third node control circuit can include two control sub-circuits. In the display stage, the two control sub-circuits work alternately (they can be switched once in each frame or every 2 seconds) to avoid the transistors included in the control sub-circuit being in a positive bias state for a long time, thereby ensuring the service life of the product.

[0118] like Figure 3 As shown, in Figure 1 Based on the embodiment of the driving circuit shown, the on-off control line may include a first on-off control line SW1 and a second on-off control line SW2;

[0124] Optionally, the first control subcircuit includes a first transistor, and the second control subcircuit includes a second transistor;

[0125] The gate of the first transistor is electrically connected to the first on / off control line, the first electrode of the first transistor is electrically connected to the first node, and the second electrode of the first transistor is electrically connected to the third node;

[0126] A gate of the second transistor is electrically connected to the second on / off control line, a first electrode of the second transistor is electrically connected to the first node, and a second electrode of the second transistor is electrically connected to the third node.
