Description

Integrated touch display panel

The invention relates to a display panel, in particular to a display panel with integrated touch.

Capacitive touch screens with a user interface for gesture recognition are leading the trend of introducing touch screen functions in electronic products. The operating principle of a general projected capacitive touch panel is mainly based on the capacitive induction caused by the contact between the touch electrodes on the touch panel and the human finger or a conductive object, which is converted to be read by the operating system through back-end computing. Coordinate data.

In order to realize coordinate reading, in the structure of the projected capacitive touch panel, there are generally single-layer or double-layer touch electrodes arranged in a staggered manner with different axial directions (eg, defined as X-axis and Y-axis). These touch electrodes are then electrically connected to the front-end circuit of the touch IC via a wire for transmission of touch signals. When no conductive object is in contact, there will be a fixed coupling capacitance between the touch electrodes, and the electric field distribution between the electrodes is fixed at this time.

At present, two common judgment methods are self-capacity and mutual-capacity. In the online self-capacitance judgment method, ideally, when the user touches the touch panel with a single finger or a single point, at the same time, there will be an X-axis touch electrode and a Y-axis touch electrode to generate capacitance values. Variety. Therefore, the coordinate position of a single touch can be obtained through the intersection of the X-axis and the Y-axis. However, when touching the touch screen with two fingers, for a touch IC that adopts the self-capacitive technology judgment method, the front-end circuit will perceive two X-axis touch electrodes and two Y-axis touch electrodes. The control electrode generates a signal response that changes the induced capacitance, and the intersection produces four touch points. Therefore, in the case of multi-finger or multi-touch, the front-end circuit may misreport Ghost Points, and the coordinate points actually touched cannot be determined. Therefore, with the current technology, the self-capacitive sensing method is not suitable for the real multi-touch function requirements.

Please refer to FIG. 14 to describe the operation mode of the display panel provided by the present invention. FIG. 14 is a flowchart of steps of the display panel control method according to an embodiment of the present invention.

The trace and each fourth touch trace, and each transmission trace is respectively connected to each transmission electrode. The control module first provides the first test signal to each transmission electrode through the transmission line TX (step S101). Next, the control module determines whether there is a touch point on the display panel according to the signal change amount of the touch trace (step S102). Specifically, the control module determines whether or not the current display panel is currently on the display panel based on the amount of signal change on each of the first touch traces and each of the second touch traces or each of the third touch traces and each of the fourth touch traces.

It can be determined that each touch point is located at a relative position on the display panel 1 by each touch trace having a relatively high voltage level or each touch trace having a relatively low voltage level. The following sections are detailed by examples.

When there are touch points on the display panel, it is determined whether the number of touch points is multiple according to the voltage level of each touch trace (step S103). For example, when detecting the first touch traces RX11 ~ RX14 and the second touch traces RX21 ~ RX24, the voltage levels of multiple touch traces are relatively high voltage levels or relatively low Voltage level, or when detecting the third touch traces RX31 ~ RX34 and the fourth touch traces RX41 ~ RX44, the voltage levels of multiple touch traces are relative high voltage levels or relative Low voltage level, it is judged that the number of touch points is multiple. Conversely, when detecting the first touch traces RX11 ~ RX14 and the second touch traces RX21 ~ RX24, the voltage level of only one touch trace is a relatively high voltage level or a relatively low voltage Level, and the third touch trace RX31 ~ RX34 and the fourth touch trace RX41 ~ RX44 have only one touch trace whose voltage level is a relatively high voltage level or a relatively low voltage Level, it is judged that the number of touch points is one. From another perspective, step S103 can be used to determine whether the user touches the touch panel with multiple fingers. The touch point is, for example, a touch point generated when a user touches the display panel with a finger or a stylus. The control module is, for example, a display driver integrated chip (Touch with Display Driver, TDDI), but it is not limited to this.

When the number of touch points is one, the coordinates of the touch points are determined according to the amount of signal change on the touch trace (step S107). In this embodiment, the touch point can be found according to the voltage level of the first touch trace and the second touch trace, or according to the signal change of the third touch trace and the fourth touch trace. coordinate. For example, when the voltage level of the first touch trace RX11 is a relatively high voltage level or a relatively low voltage level, and the voltage level of the fourth touch trace RX41 is When the relative high voltage level or the relatively low voltage level is determined, it is determined that there is a touch point near the intersection of the first touch line RX11 and the fourth touch line RX41.

Check whether the touch points are all associated with one of the first touch trace and the second touch trace or one of the third touch trace and the fourth touch trace (step S104 ). For example, when it is determined that the voltage level of the first touch trace RX12 is a relatively high voltage level, and the third touch trace RX32, the third touch trace RX33, and the third touch trace RX34 are Relative to the high voltage level, it can be determined that multiple touch points are simultaneously associated with the first touch line RX12. Or, in another situation, when it is determined that the voltage level of the fourth touch trace RX42 is a relatively high voltage level, and the first touch trace RX12, the first touch trace RX13, and the first touch The trace RX14 is at a relatively high voltage level, and it can be determined that multiple touch points are simultaneously associated with the fourth touch trace RX42.

According to the signal change amount of one of the first touch trace and the second touch trace or the signal change amount of one of the third touch trace and the fourth touch trace The coordinates of the touch point (step S108). Continuing the example given in step S104, when it is determined that there are multiple touch points, and the multiple touch points are associated with one of the first touch lines RX11 to RX14 and the second touch lines RX21 to RX24, it is more based on Those with a relatively high voltage level or a relatively low voltage level in the third touch lines RX31 to RX34 and the fourth touch lines RX41 to RX44 determine the positions of the multiple touch points. More precisely, it determines which staggered points of touch traces the touch points are associated with. For example, when the voltage level of the first touch trace RX22 is a relatively high voltage level or a low voltage level, and the voltage level of the third touch trace R32, R33 is a relatively high voltage level When the voltage is at a low voltage level, the first touch line RX22 can determine that a touch point is located near the first touch line and determine the coordinates of the touch point on one of the axes. In addition, it can be determined from the third touch traces R32 and R33 that there are two touch points in the axial direction, and the coordinates of the two touch points in one of the axial lines are related to the first touch trace RX22. The coordinates of the two touch points on the other axis are respectively associated with the third touch lines R32 and R33. Therefore, the relative coordinates of multiple touch points are defined in the above situation. From another perspective, step S108 can be used to determine whether the user touches the same axis of the touch panel with multiple fingers.

The second test signal is sequentially provided to at least one transmitting electrode associated with the touch point. (Step S105). When the second test signal is provided to one of the transmitting electrodes, it is judged based on the signal change amount of the first touch trace and the second touch trace or the signal change amount of the third touch trace and the fourth touch trace. The coordinates of the touch point are output (step S106).

For a practical example, when there are two touch points, and one touch point is associated with the first touch trace RX12 and the fourth touch trace RX41, the other touch point is associated with the first When touch trace RX14 and fourth touch trace RX42, that is, the first touch trace RX12, the first touch trace RX14, the fourth touch trace RX41, and the fourth touch trace RX42 are opposite High voltage level or low voltage level. If the first touch trace RX12, the first touch trace RX14, the fourth touch trace RX41 and the fourth touch trace RX42 are directly judged, four interlaced points will be obtained. Two of the interlaced points correspond to the actual touch points, while the other two interlaced points are ghost points. In the method proposed above, the problem of false positives can be avoided.

If illustrated in FIG. 1, in step S105, a second test signal is sequentially provided to the transmission lines TX1 to TX4. In other words, in this step, only the second test signal is provided to one of the transmission lines TX1 to TX4 at the same time. It does not limit the order in which the second test signal is provided to the transmission lines X1 to TX4, nor does it limit the appearance of the second test signal. In one embodiment, the second test signal may be the same as the first test signal. The following description is made by taking the second test signal in sequence to the transmission line TX1, the transmission line TX2, the transmission line TX3, and the transmission line TX4 as an example.

The transmission line TX1 corresponds to the intersection of the first touch line RX11 and the third touch line RX31 ~ RX34 and the fourth touch line RX41 ~ RX44, and corresponds to the second touch line RX21 and the third The intersections of the touch lines RX31 ~ RX34 and the fourth touch lines RX41 ~ RX44. When a second test signal is provided to the transmission line TX1, none of the first touch line RX11, the second touch line RX21, the third touch line RX31 ~ RX34, and the fourth touch line RX41 ~ RX44 are provided. Has a relatively high voltage level or a relatively low voltage level. Therefore, it is determined that no touch point is associated with the intersection of the first touch trace RX11 and the third touch trace RX31 ~ RX34 and the fourth touch trace RX41 ~ RX44, and no touch point is associated with the second touch The intersection of trace RX21, third touch trace RX31 ~ RX34, and fourth touch trace RX41 ~ RX44.

The transmission trace TX2 corresponds to the intersection of the first touch trace RX12 and the third touch trace RX31 ~ RX34 and the fourth touch trace RX41 ~ RX44, and corresponds to the second touch trace RX22 and the third The intersections of the touch lines RX31 ~ RX34 and the fourth touch lines RX41 ~ RX44. When a second test signal is provided to the transmission line TX2, both the first touch line RX12 and the fourth touch line RX41 have a relatively high voltage level or a relatively low voltage level. Therefore, it is determined that there is a touch point near the intersection of the first touch line RX12 and the fourth touch line RX41.

The transmission line TX3 corresponds to the intersection of the first touch line RX13 and the third touch line RX31 ~ RX34 and the fourth touch line RX41 ~ RX44, and corresponds to the second touch line RX23 and the third The intersections of the touch lines RX31 ~ RX34 and the fourth touch lines RX41 ~ RX44. When the second test signal is provided to the transmission line TX3, none of the first touch line RX13, the second touch line RX23, the third touch line RX31 ~ RX34, and the fourth touch line RX41 ~ RX44 are provided. Has a relatively high voltage level or a relatively low voltage level. Therefore, it is determined that no touch point is associated with the intersection of the first touch trace RX13 and the third touch trace RX31 ~ RX34 and the fourth touch trace RX41 ~ RX44, and no touch point is associated with the second touch The intersections of traces RX23, third touch traces RX31 ~ RX34, and fourth touch traces RX41 ~ RX44.

The transmission trace TX4 corresponds to the intersection of the first touch trace RX14 and the third touch trace RX31 ~ RX34 and the fourth touch trace RX41 ~ RX44, and corresponds to the second touch trace RX24 and the third touch trace. The intersections of the touch lines RX31 ~ RX34 and the fourth touch lines RX41 ~ RX44. When a second test signal is provided to the transmission line TX4, both the first touch line RX14 and the fourth touch line RX42 have a relatively high voltage level or a relatively low voltage level. Therefore, it is determined that another touch point is located near the intersection of the first touch trace RX14 and the fourth touch trace RX42. From another perspective, step S105 can be used to determine whether the user touches multiple axes of the touch panel with multiple fingers.
