[Prior Art] Since the amorphous germanium material has a photosensitive property as the nth θ θ of the touch liquid crystal panel, the third switching element composed of the non-fourth material and the optical signal read by the second processing The layout of the circuit and the conventional technique: the process technology of the crystal liquid crystal display system is completely different from the touch-type liquid crystal panel of the non-daily plus the touch panel, so as to make the Γ phase: = material as the third switching component The human touch panel has a lower production cost due to the private phase of the I. The touch = 〇 formed by the external touch panel method. / panel ^ port is the influence of the transmittance of the touch panel to reduce the transmittance, and the embedded touch light transmittance using the amorphous germanium material as the third switching element is only read and read (Pixed) The three switching elements in the structure are related to the optical signal readout line layout. 2 'If the third switching element in each readout element and its readout line, f2 are properly calculated, the aperture ratio of the touch-sensitive liquid crystal panel is not the first switching element and the readout line. The design has too much impact. Read more in the first section of the month, which shows the readout pixel richness of the touch-sensitive liquid crystal panel according to the conventional technique t, and the 1325995 circuit diagram of the third switching element. As shown in the figure, the third switching element includes a photosensitive film transistor 121 as a light sensing element for generating an optical signal and transmitting a thin film transistor as a switching element 122 by a readout line (Readout). Line) read out. The gate of the photosensitive film transistor 121 is connected to the gates D and G by a bias voltage Vb, and the source S thereof is connected to the readout line via the thin film transistor switching element 122. As can be seen from Fig. 1, the drain D of the thin film transistor switching element 122 is connected to the source S of the photosensitive film transistor 121, and the gate G and its source S are respectively connected to the read. A gate line of the pixel is drawn on the read line. Please refer to FIG. 2(A), which shows a bonding pad on a substrate of a liquid crystal display in the prior art, including a gate pad and a pad. The schematic diagram of the configuration is to connect to the driver 1C via the module process. As shown in the figure, in a conventional liquid crystal display structure, the gate line bonding pad 55 and the data line bonding pad 45 are respectively disposed on two sides adjacent to the substrate, wherein the gate line is arranged. One side of the bonding pad 55 is also referred to as a gate line side, and the side for arranging the data line bonding pad 45 is referred to as a data line side. The gate line bonding pad 55 and the data line bonding pad 45 respectively connect each gate line and data line on the liquid crystal display to their respective driving 1C outputs, so that the gate line signal of the driving 1C output is The data signal can be transmitted through the gate wire bonding pad 55 and the data wire bonding pad 45 to the mother's one gate line and the lean line* of the liquid crystal display to effectively drive the display area of the display. However, in the touch-control liquid crystal panel, in addition to the aforementioned gate line and the 1325995 material line, the configuration of the readout line of the optical signal must be added, so the line configuration on the touch liquid crystal panel will be more complicated. . Please refer to FIG. 2(B), which is a schematic view showing the arrangement of the readout line 31 and its corresponding readout line bond pad 35 on a substrate in a conventional touch liquid crystal panel. As shown in the figure, in the case where a large number of read lines 31 are arranged and the gate line bonding pad 55 and the data line bonding pad 45 have been disposed on the 'gate line side and the data line side' on the substrate, the read line The bonding pads 35 can only be disposed on the additional side of the substrate to connect each of the readout lines 31 to their corresponding readout lines 1C. In this case, an additional area 33 must be planned on the substrate of the touch-control liquid crystal panel to lay out the read line bond pad 35. The change of the substrate area may result in a touch-sensitive liquid crystal panel module. Process generation is incompatible with traditional LCD panel module processes. Therefore, the readout line 31 of the conventional touch panel and its corresponding readout line bond pad 35 are configured to increase the manufacturing cost due to the incompatibility of the module process. For the sake of the job, the applicant's readout of the pixel structure of the pixel structure affects the aperture ratio of the display, and the readout line and the readout line bond pad, in view of the embedded touch surface φ board in the prior art. The configuration of 35 also has the problem of incompatibility of the module process. Therefore, it is a perseverance spirit. After careful experimentation and research, a new "liquid crystal display with embedded third switching element" is finally conceived to effectively Overcoming the aforementioned shortcomings of conventional embedded panel commands.

As shown in the figure, each of the readout lines 3M, 31_2, . . . , 31·Ν is connected to the respective readout lines by the respective readouts of the respective readout elements, and is connected to the entire -35. However: in such a line layout, each light-sensing element on the readout element must have a sufficient area to induce a sufficiently large photocurrent, f. It is often necessary to make the light sensing unit of the readout pixel occupy a large area range in order to exert the utility of the light sensing unit.

The interference of the applied voltage, therefore, the portion of the pixel electrode 105 covering the third switching element 103 must be removed to make the sensitization effect: as shown in Fig. 7 (9). However, = the portion of the third switching element 103 is removed. - switching the liquid crystal molecules at several pieces 103 may cause a light leakage due to the fringe electric field caused by the light perception. Case ❶ == In such a case, 'the extension of the metal layer of the two poles constituting the third switching element ι〇3, as in the metal 丄 7 in the figure (9) Happening. However, in such a way, the opening σ rate of the pixel is affected. In order to effectively overcome the structural design of the readout pixel 1G in the foregoing embodiment of the present invention, it is also possible to control the coverage area of the pixel electrode and avoid the closed-pole metal 亍 (4) 7 diagram (〇 and 7 (9), The top view is a top view and a cross-sectional view of a first switching element Η) 3 included in a read pixel structure shown in FIG. 7 (8), which is the third switch read in FIG. 7 (9). Element 103 is a cross-sectional structure taken from the 'hatching line' shown in Fig. 7(c). As shown in FIG. 7 (8), the third gate of the second switching element 103 has a shape in which the substrate is fine, and the third source 1032 and the third drain 1 〇 33 of the third switching element 103 are formed. Above the third gate, and having a gate insulating layer 210 therein in an electrically insulated state from each other. Further, the pixel electrode layer 1〇5 is formed over the third source 032, and there is also a case where the insulating layer 220 is electrically insulated from each other. As can be seen from FIG. 7( ), FIG. 7(D ) 10 , in order to reduce the extension of the gate metal layer, the pixel structure may extend through the pixel electrode 1〇5 to the third source 1032. Above the layer, the area a as defined in Fig. 7 (9) is used to solve the problem of light leakage of the crystal layer. The same technique of extending the third source layer through the pixel electrode layer 105 can also be applied to the third gate and the third source over the 'covering with a halogen electrode' to avoid the edge. The electric field can reduce the width of the gate metal. Therefore, the aperture ratio of the readout element can be effectively maintained. 1325995 - In summary, in the above (4), a liquid crystal display touch panel having an I-type third switching π-piece is proposed to effectively overcome the lack of the conventional touch-type liquid crystal display.
