All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of a touch display screen according to an embodiment; fig. 2 is a schematic structural diagram of the touch display screen shown in fig. 1 in another embodiment.
The embodiment of the present application provides a touch display screen 100, where the touch display screen 100 may have a six-layer structure (as shown in fig. 1), and includes a control circuit 10, a routing layer 20, a shielding layer 30, a row line layer 40, a column line layer 50, and a light emitting layer 60, which are stacked in a stacked manner. It is understood that a substrate 70 may be disposed between the various layers of the structure to provide load bearing. The substrate 70 may be a circuit board, and is made of glass fiber epoxy, polyimide, or any other material that meets the corresponding functional requirements, and the material of the substrate 70 is not specifically limited herein.
The control circuit 10 is used for controlling the currents on the row line layer 40 and the column line layer 50 to realize the display function and the touch function. In one embodiment, the control circuit 10 includes a first chip (not shown) and a second chip (not shown), the first chip is used for providing a display driving current to control the display function; the second chip is used for providing touch driving current and receiving touch induced current so as to control and realize a touch function; the first chip and the second chip cooperate to enable the touch display screen 100 to have both display and touch functions. In another embodiment, the control circuit 10 includes a third chip (not shown), and the third chip can be used for providing a display driving current, providing a touch driving current, and receiving a touch sensing current, so that the touch display screen 100 can have both display and touch functions only through the third chip. It is understood that the types and the number of chips in the control circuit 10 may be various, as long as the display function and the touch function can be controlled, and the types and the number of chips in the control circuit 10 are not specifically limited herein.
The routing layer 20 is disposed between the control circuit 10 and the row line layer 40, and the routing layer 20 is used to electrically connect the control circuit 10 to the row line layer 40 and the column line layer 50, respectively, so as to effectively implement corresponding control functions. The shielding layer 30 is disposed between the routing layer 20 and the row line layer 40, and the shielding layer 30 is used for shielding signals to prevent the signals in the touch display screen 100 from interfering with external electronic devices. The light emitting layer 60 is composed of a plurality of light emitting devices 61 arranged in an array for emitting light to realize a display function, and the row line layer 40, the column line layer 50, the routing layer 20 and the shielding layer 30 are disposed between the light emitting layer 60 and the control circuit 10.
It can be understood that when the arrangement density of the light emitting devices 61 is small and the pitch between the light emitting devices 61 is large, the control circuit 10 has enough space to route with the row line layer 40 and the column line layer 50, in this case, the routing layer 20 can be omitted; alternatively, the shielding layer 30 is arranged to cover only the position corresponding to the light emitting device 61, so as to combine the wiring layer 20 and the shielding layer 30 into the same layer structure. It is also understood that the light emitting layer 60 can be omitted to meet the corresponding requirements, that is, the light emitting device 61 and the column line layer 50 are arranged in the same layer structure, as long as the light emitting device 61 is located on the surface layer of the touch display screen 100 to realize the display function. As mentioned above, the touch screen display 100 can also be a four-layer structure (see FIG. 2). It should be noted that the touch display screen 100 provided in the embodiment of the present application may also be in other multilayer structures, and the number of layers of the layer structure of the touch display screen 100 is not specifically limited herein.
Referring to fig. 3 and fig. 4 together, fig. 3 is a schematic diagram illustrating a display driving principle of the touch display screen shown in fig. 1; fig. 4 is a schematic diagram of a touch driving principle of the touch display screen shown in fig. 1.
In the touch display screen 100 provided in the embodiment of the present application, the row line layer 40 includes a plurality of scan lines 41 extending in a row direction, and the column line layer 50 includes a plurality of data lines 51 extending in a column direction. The plurality of light emitting devices 61 are arranged in an array, and the plurality of light emitting devices 61 in one row are electrically connected with one scanning line 41 for scanning the whole row; a plurality of light emitting devices 61 on one column are electrically connected to one data line 51. The control circuit 10 supplies a display drive current to the data lines 51 and sequentially connects the plurality of scanning lines 41 to a fixed potential so that the display drive current sequentially flows between the data lines 51 and the scanning lines 41 connected to the fixed potential, whereby the light emitting devices 61 of one row connected to the scanning lines 41 emit light. During one frame time of displaying on the touch display screen 100, the plurality of rows of scan lines 41 are sequentially connected to fixed potentials so that the plurality of rows of light emitting devices 61 connected thereto sequentially emit light, and due to the persistence of vision effect, the touch display screen 100 displays a complete picture during the above one frame time to realize the display function.
It is understood that, in the present embodiment, the touch display panel 100 is a common cathode display panel, that is, the anode 611 of the light emitting device 61 is connected to the data line 51, and the cathode 612 of the light emitting device 61 is connected to the scan line 41, under the above configuration, the control circuit 10 controls the fixed potential connected to the scan line 41 to be a low potential, that is, the potential of the scan line 41 is lower than the potential of the data line 51, and the display driving current flows from the anode 611 of the light emitting device 61 connected to the data line 51 to the cathode 612 of the light emitting device 61 connected to the scan line 41, so as to effectively implement the display function. In a specific embodiment, the control circuit 10 controls the scan lines 41 to be grounded to meet the corresponding potential requirement.
It should be noted that, within one frame time displayed by the touch display screen 100, a plurality of display periods 101 and a plurality of touch periods 102 are included, and for the common cathode display screen, the control circuit 10 provides a display driving current to the data line 51 in the display period 101, and connects the scan line 41 to a low potential, so as to make the light emitting device 61 emit light, thereby implementing a display function; the control circuit 10 provides a touch driving current to the scan lines 41 and receives a touch sensing current from the data lines 51 in the touch period 102, so that the scan lines 41 are multiplexed as output electrodes (TX) and the data lines 51 are multiplexed as receiving electrodes (RX), thereby implementing a touch function. It should be noted that, in this embodiment, since the scanning lines 41 are multiplexed as output electrodes (TX) and the data lines 51 are multiplexed as receiving electrodes (RX), in order to effectively implement a corresponding touch function, the column line layer 50 where the data lines 51 are located should be disposed on the surface of the touch display screen 100, that is, the column line layer 50 is disposed on a side of the row line layer 40 away from the control circuit 10.
It is understood that, in a general case where the light emitting device 61 is a three-color light emitting diode, a current may be transmitted from the anode 611 to the cathode 612 of the light emitting device 61, but may not be transmitted from the cathode 612 to the anode 611 of the light emitting device 61. Therefore, since the anode 611 of the light emitting device 61 is connected to the data line 51 and the cathode 612 of the light emitting device 61 is connected to the scan line 41, when the touch driving current is provided to the scan line 41 in the touch period 102 and the touch sensing current is received from the data line 51, the relevant touch current can only be transmitted through the coupling capacitance formed between the scan line 41 and the data line 51, but not through the light emitting device 61, so that the relevant touch current is effectively prevented from flowing through the light emitting device 61 to affect the display function thereof, and the touch sensitivity of the touch display screen 100 is effectively ensured not to be affected.
In one embodiment, in the touch period 102, the control circuit 10 provides a touch driving current to the adjacent scan lines 41. It is understood that, in consideration of matching between the light emitting device 61 pitch and the touch electrode pitch, the short circuit between the adjacent scan lines 41 may be controlled as one output electrode in the touch period 102 to meet the pitch requirement of the corresponding touch electrode.
