CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation application of U.S. application Ser. No. 13/775,258, filed Feb. 25, 2013. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention is related to a touch-sensing display panel module and related driving method, and more particularly, to a touch-sensing display panel module and related driving method which increase pixel charge time or reset time. 
         [0004]    2. Description of the Prior Art 
         [0005]    Touch-sensing display panels have been widely used in electronic products such as personal digital assistants (PDAs), mobile phones, notebook computers or personal computers. Touch-sensing display panels can provide a more intuitive interface between the user and the electronic device by receiving touch commands. With rapid shrinkage in size, there is less room for traditional input devices such as keyboards or mice. Therefore, touch-sensing panels providing tactile inputs and display function have become more and more popular. 
         [0006]    According to structure designs, there are two major types of touch-sensing display panels: out-cell type and in-cell type. In an out-cell type touch-sensing display panel, a touch-sensing panel and a display panel are manufactured separately and then attached to each other in subsequent process. In an in-cell type touch-sensing display panel, touch-sensing array and signal readout lines are disposed directly on an inner surface of a substrate in the display panel. In-cell type touch-sensing display panels have become the mainstream products due to thin appearance, high transmittance and low manufacturing costs 
         [0007]    In a prior art in-cell type touch-sensing display panel, a sensing unit is integrated into a thin film transistor (TFT) array. In other word, a pixel of the in-cell type touch-sensing display panel includes the sensing unit for detecting touch command and the TFT for displaying images according to various driving signals and detecting signals. A prior art sensing unit typically includes a readout TFT switch and a reset TFT switch. When applied to a small-sized panel, signal readout and voltage reset may easily be achieved since there is sufficient time for switching the TFTs. When applied to a large-sized touch panel, RC delay may result in insufficient signal readout time and voltage reset time, thereby influencing the sensing ability of the touch-sensing display panel.

     DETAILED DESCRIPTION 
       [0018]      FIGS. 1-6  are diagrams illustrating the structure and operation of touch-sensing display panel modules  101 - 106  according to embodiments of the present invention. Each of the touch-sensing display panel module  101 - 106  includes a plurality of pixels PX, a plurality of data lines DL 1 -DL M , and a plurality of gate lines GL 1 -GL N  (M and N are positive integers). Each pixel PX is coupled to a corresponding data line and a corresponding gate line. The data lines DL 1 -DL M  are arranged to transmit pixel voltages to each column of pixels. The gate lines GL 1 -GL N  are arranged to control the refreshing of each row of pixels. The touch-sensing display panel modules  101 - 106  include sensing units  11 - 16 , respectively, for determining if a touch event occurs by performing signal readout and voltage reset during a sensing period. 
         [0019]    In the embodiment demonstrated on the right side of  FIG. 1 , each sensing unit  11  includes a signal readout line SL, a storage unit ST, a readout unit  21 , and a reset unit  31 . Each storage unit ST is coupled to a detecting node N for storing the voltage level of the detecting node N. Each readout unit  21  includes a transistor TR 1  having a first end coupled to the signal readout line SL, a second end coupled to the detecting node N, and a control end coupled to a corresponding gate line GL i  among the gate lines GL 1 -GL N  (i is an integer between 1 and N). Each reset unit  31  includes transistors TS 1  and TS 2 : the transistor TS 1  includes a first end coupled to the detecting node N, a second end for receiving a reset signal S i , and a control end coupled to a corresponding gate line GL i+1  among the gate lines GL 1 -GL N ; the transistor TS 2  includes a first end coupled to the detecting node N, a second end for receiving a reset signal S i+1 , and a control end coupled to a corresponding gate line GL i+2  among the gate lines GL 1 -GL N . The signal readout line SL is arranged to receive the voltage level of the detecting node N via the readout unit  21  and transmit a corresponding sensing signal SENSE. Before a sensing period ends, the reset unit  31  is configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0020]    On the left side of  FIG. 1  is a timing diagram illustrating the operation of the touch-sensing display panel module  101 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. During the enable period of the gate control signal G i , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 , and the reset unit  31  may reset the corresponding storage unit ST via the transistor TS 2 . During the enable period of the gate control signal G i+1 , the reset unit  31  may reset the corresponding storage unit ST via the transistor TS 1 . For example, for the transistor TR 1  whose gate is coupled to the gate line GL 1 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 1 ; the transistor TS 1  whose gate is coupled to the gate line GL 2  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 2 ; for the transistors TR 1  and TS 2  whose gates are coupled to the gate line GL 3 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 3 , and the transistor TS 2  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 3 ; and the readout units  21  and the reset units  31  coupled to other gate lines may operate in the same manner as described above. Therefore, during a sensing period of the touch-sensing display panel module  101  according to the first embodiment of the present invention, the sensing unit  11  is configured to perform one signal readout operation and two voltage reset operations. With T representing the refresh period of each pixel, a signal readout time T is required for the signal readout line SL to receive the voltage level of the detecting node N via the readout unit  21  each time and for the reset unit  31  to reset the corresponding storage unit ST each time. Therefore, during each sensing period of the touch-sensing display panel module  101 , the overall readout time is T and the overall reset time is 2T. 
         [0021]    In the embodiment demonstrated on the right side of  FIG. 2 , each sensing unit  12  includes a signal readout line SL, a storage unit ST, a readout unit  22 , and a reset unit  32 . Each storage unit ST is coupled to a detecting node N for storing the voltage level of the detecting node N. Each readout unit  22  includes transistors TR 1  and TR 2 : the transistor TR 1  includes a first end coupled to the signal readout line SL, a second end coupled to the detecting node N, and a control end coupled to a corresponding gate line GL i  among the gate lines GL 1 -GL N  (i is an integer between 1 and N); the transistor TR 2  includes a first end coupled to the signal readout line SL, a second end coupled to the detecting node N, and a control end coupled to a corresponding gate line GL i+1  among the gate lines GL 1 -GL N . Each reset unit  32  includes transistors TS 1  and TS 2 : the transistor TS 1  includes a first end coupled to the detecting node N, a second end for receiving a reset signal S i+1 , and a control end coupled to a corresponding gate line GL i+2  among the gate lines GL 1 -GL N ; the transistor TS 2  includes a first end coupled to the detecting node N, a second end for receiving a reset signal S i+2 , and a control end coupled to a corresponding gate line GL i+3  among the gate lines GL 1 -GL N . The signal readout line SL is arranged to receive the voltage level of the detecting node N via the readout unit  22  and transmit a corresponding sensing signal SENSE. Before a sensing period ends, the reset unit  32  is configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0022]    On the left side of  FIG. 2  is a timing diagram illustrating the operation of the touch-sensing display panel module  102 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. During the enable period of the gate control signal G i , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 , and the reset unit  32  may reset the corresponding storage unit ST via the transistor TS 2 . During the enable period of the gate control signal G i+1 , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 2 . During the enable period of the gate control signal G i+2 , the reset unit  32  may reset the corresponding storage unit ST via the transistor TS 1 . For example, for the transistor TR 1  whose gate is coupled to the gate line GL 1 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 1 ; for the transistor TR 2  whose gate is coupled to the gate line GL 2 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 2  during the enable period of the gate control signal G 2 ; the transistor TS 1  whose gate is coupled to the gate line GL 3  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 3 ; for the transistors TS 2  and TR 1  whose gates are coupled to the gate line GL 4 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 4 , and the transistor TS 2  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 4 ; and the readout units  22  and the reset units  32  coupled to other gate lines may operate in the same manner as described above. Therefore, during a sensing period of the touch-sensing display panel module  102  according to the second embodiment of the present invention, the sensing unit  12  is configured to perform two signal readout operations and two voltage reset operations. With T representing the refresh period of each pixel, a signal readout time T is required for the signal readout line SL to receive the voltage level of the detecting node N via the readout unit  22  each time and for the reset unit  32  to reset the corresponding storage unit ST each time. Therefore, during each sensing period of the touch-sensing display panel module  102 , the overall readout time is 2T and the overall reset time is 2T. 
         [0023]    In the embodiment demonstrated on the right side of  FIG. 3 , each sensing unit  13  includes a signal readout line SL, a storage unit ST, a readout unit  23 , and a reset unit  33 . Each storage unit ST is coupled to a detecting node N for storing the voltage level of the detecting node N. Each readout unit  23  includes a transistor TR 1  having a first end coupled to the signal readout line SL, a second end coupled to the detecting node N, and a control end coupled to a corresponding gate line GL i  among the gate lines GL 1 -GL N  (i is an integer between 1 and N). Each reset unit  33  includes a transistor TS 1  having a first end coupled to the detecting node N, a second end for receiving a reset signal S i+1 , and a control end coupled to a corresponding gate line GL i+2  among the gate lines GL 1 -GL N . The signal readout line SL is arranged to receive the voltage level of the detecting node N via the readout unit  23  and transmit a corresponding sensing signal SENSE. Before a sensing period ends, the reset unit  33  is configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0024]    On the left side of  FIG. 3  is a timing diagram illustrating the operation of the touch-sensing display panel module  103 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. The enable period of each gate control signal is larger than a pixel refresh period T (the duration each time a pixel is being refreshed). The enable period of each gate control signal is overlapped with the enable period of at least another gate control signal, and the overlapped enable period is equal to or larger than T. During the enable period of the gate control signal G i , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 . During the enable period of the gate control signal G i+2 , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 , and the reset unit  33  may reset the corresponding storage unit ST via the transistor TS 1 . For example, for the transistor TR 1  whose gate is coupled to the gate line GL 1 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 1 ; for the transistors TR 1  and TS 1  whose gates are coupled to the gate line GL 3 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the gate control signal G 3 , and the transistor TS 1  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 3 ; and the readout units  23  and the reset units  33  coupled to other gate lines may operate in the same manner as described above. Therefore, during a sensing period of the touch-sensing display panel module  103  according to the third embodiment of the present invention, the sensing unit  13  is configured to perform one signal readout operation and one voltage reset operation. The overall readout time and the overall reset time may be larger than T (such as 2T). 
         [0025]    In the embodiment demonstrated on the right side of  FIG. 4 , each sensing unit  14  includes a signal readout line SL, a sensing scan line (one of W i -W P , P is a positive integer), a storage unit ST, a readout unit  24 , and a reset unit  34 . Each storage unit ST is coupled to a detecting node N for storing the voltage level of the detecting node N. Each readout unit  24  includes a transistor TR 1  having a first end coupled to the signal readout line SL, a second end coupled to the detecting node N, and a control end coupled to a corresponding sensing scan line W j  (j is an integer between 1 and P). Each reset unit  34  includes a transistor TS 1  having a first end coupled to the detecting node N, a second end for receiving a reset signal S j , and a control end coupled to a corresponding gate line GL i  among the gate lines GL 1 -GL N . The signal readout line SL is arranged to receive the voltage level of the detecting node N via the readout unit  24  and transmit a corresponding sensing signal SENSE. Before a sensing period ends, the reset unit  34  is configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0026]    On the left side of  FIG. 4  is a timing diagram illustrating the operation of the touch-sensing display panel module  104 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. The enable period of each gate control signal is equal to a pixel refresh period T (the duration each time a pixel is being refreshed) and is not overlapped with the enable period of any other gate control signal. The enable period of each sensing scan line is equal to or larger than the pixel refresh period T and is not overlapped with the enable period of any other sensing scan line. During the enable period of the sensing scan line W j , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 . During the enable period of the gate control signal G i , the reset unit  34  may reset the corresponding storage unit ST via the transistor TS 1 . For example, for the transistor TR 1  whose gate is coupled to the sensing scan line W 1 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the sensing scan line W 1 ; for the transistors TR 1  and TS 1  whose gates are coupled to the sensing scan line W 2 , the signal readout line SL is arranged to receive the voltage level of the detecting node N via the transistor TR 1  during the enable period of the sensing scan line W 2 , and the transistor TS 1  is arranged to reset the corresponding storage unit ST during the enable period of the sensing scan line W 2 ; and the readout units  24  and the reset units  34  coupled to other sensing scan lines may operate in the same manner as described above. Therefore, during a sensing period of the touch-sensing display panel module  104  according to the fourth embodiment of the present invention, the sensing unit  14  is configured to perform one signal readout operation and one voltage reset operation. The overall readout time may be larger than T (such as 2T). 
         [0027]    In the embodiment demonstrated on the right side of  FIG. 5 , each sensing unit  15  includes a signal readout line SL, a storage unit ST, a readout unit  25 , and a reset unit  35 .

Each reset unit  35  includes a transistor TS 1  having a first end coupled to the detecting node N, a second end for receiving a reset signal S i+1 , and a control end coupled to a corresponding gate line GL i+2  among the gate lines GL 1 -GL N . The signal readout line SL is arranged to receive the voltage level of the detecting node N via the readout unit  25  and transmit a corresponding sensing signal SENSE. Before a sensing period ends, the reset unit  35  is configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0028]    On the left side of  FIG. 5  is a timing diagram illustrating the operation of the touch-sensing display panel module  105 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. The enable period of each gate control signal is larger than a pixel refresh period T (the duration each time a pixel is being refreshed). The enable period of each gate control signal is completely overlapped with the enable period of at least another gate control signal. Therefore, when the pixel voltage is provided via a data line, at least two gate control signals are during the enable period. During the enable period of the gate control signal G i , the signal readout line SL may receive the voltage level of the detecting node N via the transistor TR 1 , and the reset unit  35  may reset the corresponding storage unit ST via the transistor TS 1 .

Therefore, during a sensing period of the touch-sensing display panel module  105  according to the third embodiment of the present invention, the sensing unit  15  is configured to perform one signal readout operation and one voltage reset operation. The overall readout time may be larger than T (such as 2T).

The signal readout line SL 1  is arranged to receive the voltage level of the detecting node N 1  via the readout unit  26  and transmit a corresponding sensing signal SENSE 1 . The signal readout line SL 2  is arranged to receive the voltage level of the detecting node N 2  via the readout unit  27  and transmit a corresponding sensing signal SENSE 2 . Before a sensing period ends, the reset units  36  and  37  are configured to reset the voltage level of the storage unit ST, which may thus perform signal readout operation during the next sensing period by storing the voltage level of the detecting node N. 
         [0030]    On the left side of  FIG. 6  is a timing diagram illustrating the operation of the touch-sensing display panel module  106 . Gate control signals G 1 -G N  are provided for activating and refreshing the pixels coupled to the gate lines GL 1 -GL N  sequentially. The enable period of each gate control signal is larger than a pixel refresh period T (the duration each time a pixel is being refreshed). The enable period of each gate control signal is completely overlapped with the enable period of at least another gate control signal. During the enable period of the gate control signal G i , the signal readout line SL 1  may receive the voltage level of the detecting node N 1  via the transistor TR 1 , and the reset unit  36  may reset the corresponding storage unit ST via the transistor TS 1 ; during the enable period of the gate control signal G i+1 , the signal readout line SL 2  may receive the voltage level of the detecting node N 2  via the transistor TR 2 , and the reset unit  36  may reset the corresponding storage unit ST via the transistor TS 1 . 
         [0031]    For example, for the transistor TR 1  whose gate is coupled to the gate line GL 1 , the signal readout line SL 1  is arranged to receive the voltage level of the detecting node N 1  via the transistor TR 1  during the enable period of the gate control signal G 1 ; for the transistor TR 2  whose gate is coupled to the gate line GL 2 , the signal readout line SL 2  is arranged to receive the voltage level of the detecting node N 2  via the transistor TR 2  during the enable period of the gate control signal G 2 ; for the transistors TR 1  and TS 1  whose gates are coupled to the gate line GL 3 , the signal readout line SL 1  is arranged to receive the voltage level of the detecting node N 1  via the transistor TR 1  during the enable period of the gate control signal G 3 , and the transistor TS 1  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 3 ; for the transistors TR 2  and TS 2  whose gates are coupled to the gate line GL 4 , the signal readout line SL 2  is arranged to receive the voltage level of the detecting node N 2  via the transistor TR 2  during the enable period of the gate control signal G 4 , and the transistor TS 2  is arranged to reset the corresponding storage unit ST during the enable period of the gate control signal G 4 ; and the readout units  26 - 27  and the reset units  36 - 37  coupled to other gate lines may operate in the same manner as described above. Therefore, during a sensing period of the touch-sensing display panel module  106  according to the sixth embodiment of the present invention, the sensing unit  16  is configured to perform one signal readout operation and one voltage reset operation. The overall readout time and the rest time may be larger than T (such as 2T). 
         [0032]    In the embodiments of the present invention, the storage units ST, ST 1  and ST 2  may include a capacitive device, a photo device, a resistive device or a voltage-sensing device which may store the variations in capacitance, luminance, resistance or voltage caused by touch events.  FIGS. 7A-7C  are diagrams illustrating embodiments of capacitive storage unit, but do not limit the scope of the present invention. 
         [0033]    In the embodiments illustrated in  FIGS. 1-6 , the transistors TR 1  and TR 2  may be TFT switches or other devices having similar functions, the transistors TS 1  may be photo transistor switches, and the transistors TS 2  may be TFT switches or photo transistor switches. However, the above-mentioned devices are only embodiments and do not limit the scope of the present invention. 
         [0034]    In the embodiments of the present invention, the sensing units may be disposed on the same side of the pixel array, on both sides of the pixel array, or in the pixel array. The arrangement of the sensing units  11 - 16  in  FIGS. 1-6  are for illustrative purposes and do not limit the scope of the present invention. 
         [0035]    In conclusion, the present invention provides an in-cell type touch-sensing display panel module which adopts multiple readout units, adopting multiple reset units or increases the enable period of the gate driving signals. The overall readout time and the rest time may be larger than one pixel refresh period, thereby improving the sensing ability of the touch-sensing display panel.
