In-line display touch structure with display data line as transparent touch sensing connection line

The present invention relates to a structure of a display screen with a touch function, and more particularly to an in-line display touch structure using a display data line as a transparent touch sensing connection line.

In recent years, the flat panel display industry has developed rapidly, and many products have been proposed in order to pursue lighter weight, thinner thickness, smaller size and more detailed image quality. And several flat panel displays have been developed to replace the traditional cathode ray tube display (CRT). Conventional flat panel displays include a liquid crystal display (LCD), a plasma display panel (PDP), an Organic Light Emitting Diode (OLED) display, and a field emission display (Field Emission Display, FED), and Vacuum Fluorescence Display (VFD).

The touch-sensitive flat panel display directly overlaps the touch panel and the flat display, because the laminated touch panel is a transparent panel, so that the image can penetrate the display image of the touch panel stacked thereon. Then use the touch panel as the medium or interface for input. However, this kind of study Knowing the skill, because in the superposition, it is necessary to increase the complete weight of a touch panel, so that the weight of the flat display is greatly increased, which does not meet the requirements of the current market for the light and thin display. When the touch panel and the flat display are directly stacked, the thickness of the touch panel itself is increased in thickness, the light transmittance is reduced, the reflectance and the haze are increased, and the quality of the screen display is greatly reduced.

In response to the aforementioned shortcomings, the touch panel display adopts an embedded touch technology. The main development direction of embedded touch technology can be divided into On-Cell and In-Cell technologies. The technology of On-Cell Touch is to make the touch panel sensor on the film and then attach it to the uppermost upper substrate glass. The In-Cell Touch technology integrates the touch components into the display panel, so that the display panel itself has the touch function, so there is no need to separately process or assemble the touch panel, so the technology is usually It was developed by the display panel factory.

The capacitive touch panel detects the coordinates of the generated current or voltage by utilizing the change in capacitance generated by the electrostatic combination between the arranged transparent electrodes and the human body. FIG. 1 is a schematic view showing a conventional double-layer transparent electrode structure, and the transparent electrode is implanted according to the X-axis and the Y-axis direction. The different transparent electrode layers are separated by an insulator such as glass or plastic. The disadvantage is that the material cost is high and the manufacturing process is cumbersome.

Figure 2 is a schematic illustration of a conventional single layer transparent electrode structure. The single-layer transparent electrode structure of Fig. 2 has the advantages of saving material cost and simplifying the manufacturing process. However, the single-layer transparent electrode structure of FIG. 2 has the disadvantage that the trace 21 is complicated, and also because the trace 21 occupies a part of the area, resulting in linearity change. difference. The area occupied by the trace 21 forms a dead area, that is, the touch area cannot effectively detect the touch of the finger. Therefore, there is still room for improvement in the conventional flat display touch structure.

The main purpose of the present invention is to provide an in-line display touch structure with a display data line as a transparent touch sensing connection line, which can greatly save material cost and processing cost; since the sensing electrode block of the transparent sensing electrode layer goes The line uses a portion of the plurality of data lines of the thin film transistor layer, so that the separation distance between the sensing electrode blocks can be effectively reduced, thereby reducing the area of the dead zone and improving the linearity and correctness of the sensing.

According to one of the features of the present invention, the present invention provides an in-line display touch structure comprising a data line as a transparent touch sensing connection, comprising a first substrate, a second substrate, a thin film transistor layer, and a Transparent sensing electrode layer. The first substrate and the second substrate sandwich a display material layer between the two substrates in a parallel pair configuration. The thin film transistor layer is located on a side of the second substrate for one side of the display material layer, wherein the thin film transistor layer has a plurality of scan lines and a plurality of data lines, and the plurality of scan lines are according to a first direction The plurality of data lines are set according to a second direction. The transparent sensing electrode layer is located on a surface of the thin film transistor layer on one side of the second substrate, and has a plurality of transparent sensing electrode blocks, and the plurality of transparent sensing electrode blocks are according to the first direction and The second direction is set; wherein a portion of the plurality of data lines are electrically connected to the plurality of transparent sensing electrode blocks to transmit the plurality of The electrical signal sensed by each of the transparent sensing electrode blocks of the transparent sensing electrode block.

As shown in FIG. 6, the sub-pixel region 411 is transparent, however, due to the colored light emitted by the display material layer 130, the sub-pixel region 411 can be divided into a red sub-pixel region 411-1 and a blue sub-pixel region 411- 2 and the green sub-pixel area 411-3. The scan line 145, the data line 143, and the sub-pixel area 411 shown in FIG. 6 are for convenience of description only, and are not actual dimensions thereof.

As shown in FIG. 6, the data line 143-1 has a region overlap with the sensing electrode block 151, so that it can be electrically connected via a plurality of vias 401 to form a connecting line of the sensing electrode block 151. The electrical signal sensed by the sensing electrode block 151 is transmitted. In FIG. 6, only the data line 143-1 is electrically connected to the sensing electrode block 151, and the other data lines 143 are not electrically connected to the sensing electrode block 151, so the other data lines 143 are not implanted. Through hole.

The elliptical B in FIG. 6 is where the data line 143 overlaps the scan line 145. To prevent the sensing electrode block 151 from being electrically connected to the scan line 145, the data line 143 and the scan line 145 are not overlapped. Hole (via).

Figure 7 is a cross-sectional view taken along line AA' of the drawing of Figure 6.

At the line AA', only the local area is set to the data line 143-1, so other places where the data line is not set are indicated by broken lines. An insulating layer 149 is provided between the data line 143-1 and the scanning line 145. The insulating layer 149 may be an entire layer, or the insulating region may be disposed only in the intersection of the scanning line 145 and the data line 143-1.

8 is a schematic diagram of the sensing electrode block of the present invention. In FIG. 8, the sensing electrode block 151-1 extends downward from a data line 143-1, and then extends from a connecting line 730 to the in-line type. One side 101 of the touch display panel structure 100 is further connected to the touch control circuit 610 of a circuit board 600, and the sensing electrode blocks 151-2, ..., 151-N of the same column are respectively composed of data The lines 143-2, ..., 143-N extend downward (N is an integer greater than 1), and further extend from the connecting line 730 to one side 101 of the in-cell touch display panel structure 100 for further The touch control circuit 610 is connected to a circuit board 600. Similarly, the sensing electrode blocks 151-(N+1), ..., 151-2N of the next column are respectively connected by the data line 143-(N+1). The 143-2N extends downwardly and further extends from the connecting line 730 to one side 101 of the in-cell touch display panel structure 100 for further connection to the touch control circuit 610 of a circuit board 600. And so on to all the columns of the sensing electrode block 151, in this embodiment, it is assumed that there are m+1 columns (m is an integer greater than 1), so the sensing column block 151-(mN+1) of the last column ,...,151-(mN+N) The data lines 143-(mN+1), ..., 143-(mN+N) are respectively extended downward, and then extended by the connecting line 730 to one side of the in-cell touch display panel structure 100. 101 to further connect to the touch control circuit 610 of a circuit board 600. The touch control circuit 610 is connected to the plurality of sensing electrode blocks 151. The touch control device is used for touch sensing. The circuit 610 provides the touch driving signal, and the plurality of sensing electrode blocks 151 sense whether there is an external object approaching or touching by the plurality of connecting lines. In other embodiments, the touch control circuit 610 can also be directly placed on the second substrate 120 (lower glass substrate).

As shown in FIG. 8 , the sensing electrode block 151-1 includes 48 sub-pixel regions 411 , which is only a schematic diagram. In an actual situation, the sensing electrode block 151-1 may include hundreds to thousands of sub-pixel regions. At the same time, the plurality of sensing electrode blocks 151 can form a touch detection plane.

Another method is to increase the spacing of the red sub-pixel region 411-1 from the left green sub-pixel region 411-3 to accommodate the wider data line 143-1.

FIG. 9 is a schematic diagram of the use of the embedded display touch structure 100 for displaying a data line as a transparent touch sensing connection line, which is used in a display. As shown in FIG. 9, the data processing unit 910, a display control unit 920, a touch detection unit 930, a timing control unit 940, and a display data line are embedded as transparent touch sensing connection lines. The display touch structure 100, the plurality of display switches 950, a data transmitter 960, And a gate driver 970. In this embodiment, the embedded display touch structure 100 with the display data line as the transparent touch sensing connection line has a display and touch function. The plurality of data lines 220 are respectively connected to the plurality of display switches 950, so that when the touch detection is performed, part of the plurality of data lines 143-1, 143-2, ..., 143-(mN+ N) is electrically connected to a touch detection unit 930. When the touch detection is not performed, part of the plurality of data lines 143-1, 143-2, ..., 143-(mN+N) are electrically connected to one Data transmitter 960.

In FIG. 9, the present invention uses the display data line 143-1 as the touch sensing connection line of the sensing electrode block 151-1 to transmit the electrical signal sensed by the sensing electrode block 151-1. Therefore, when the gate driver 970 drives the scan line 145-1 to perform image display, and the touch detection unit 930 performs touch detection on the sensing electrode block 151-1, the connection with the data line 143-1 is performed. The display switch 950 switches to preferentially connect the data line 143-1 to the touch detection unit 930, and performs self-capacitance touch sensing detection. Therefore, the display of the sub-pixel area at the intersection of the scan line 145-1 and the data line 143-1 generates an error. However, there is only one sub-pixel area with incorrect data, so it does not affect the quality of the display.

When the gate driver 970 performs image display by driving the scan line 145-2, and the touch detection unit 930 performs touch detection on the sensing electrode block 151-2, the display connected to the data line 143-2 The switch 950 switches to preferentially connect the data line 143-2 to the touch detection unit 930 to perform self-capacitance touch sensing detection. At this time, the display switch 950 connected to the data line 143-1 is switched to electrically connect the data line 143-1 to the data transmitter 960. Therefore, the scan line 145-2 is handed over to the data line 143-2. Displaying data in the sub-pixel area of the meeting will generate an error. However, there is only one sub-pixel area with incorrect data and does not affect the quality of the entire displayed image.

It can be seen from the foregoing description that the sensing electrode block 151 of the present invention may include hundreds to thousands of sub-pixel regions 411, and only one sub-pixel region 411 of the hundreds of sub-pixel regions to thousands of sub-pixel regions 411 may be touch-sensitive. Detection is affected. However, in a Full HD high-definition liquid crystal display, there are at least 6220800 (1920×1080×3) sub-pixel regions 411, and even if hundreds of discontinuous sub-pixel regions 411 are affected, the human eye cannot detect it, and thus does not affect the entire display image. Quality.

FIG. 10 is another schematic diagram of the in-line display touch structure 100 in which the data line is displayed as a transparent touch sensing connection line. The main difference from FIG. 9 is that the touch detection unit 930, the plurality of display switches 950, and the data transmitter 960 are integrated into an integrated circuit. At the same time, when the touch sensing detection is performed, the touch detecting unit 930 simultaneously drives/detects a column of sensing electrode blocks 151-1, 151-2, ..., 151-N to improve the touch detection return rate ( Report rate), N is an integer greater than one. After the touch detection of the sensing electrode blocks 151-1, 151-2, ..., 151-N of one column is completed, the touch detecting unit 930 drives/detects the sensing electrode blocks of the next column.

In this embodiment, a plurality of the plurality of sensing electrode blocks 151 are electrically connected to the plurality of sensing electrode blocks 151 to transmit electrical signals induced by each of the plurality of sensing electrode blocks 151. Therefore, it is not necessary to provide a transparent sensing electrode layer made of a transparent conductive material on the upper glass substrate or the lower glass substrate of the display panel, thereby reducing the cost, reducing the process procedure, improving the process yield and reducing the process cost.

Referring to FIG. 3, the thin film transistor layer 140 further includes a plurality of pixel driving circuits 141. Each of the pixel driving circuits 141 corresponds to a sub-pixel region 411, according to a display pixel signal and a display driving signal.

The alloy is either a combination of lithium fluoride (LiF), magnesium fluoride (MgF2), lithium oxide (LiO) and Al. Since the cathode layer 170 is a metallic material, the light is reflected, so that most of the light sources are directed toward the second substrate 120 to form a lower-emitting display type.

The light generated by the display material layer 130 is reflected, and an image can be displayed on the second substrate 120. The cathode layer 170 is a whole piece of electrical connection Therefore, it can be used as a shield. At the same time, the cathode layer 170 also receives current from the anode pixel electrode 181.

The anode layer 180 is located on one side of the thin film transistor layer 140 facing the display material layer 130. The anode layer 180 has a plurality of anode pixel electrodes 181. Each anode pixel electrode of the plurality of anode pixel electrodes 181 corresponds to a pixel driving transistor of the pixel driving circuit 141 of the thin film transistor layer 140, that is, each of the plurality of anode pixel electrodes An anode pixel electrode is connected to the corresponding source/source 1415 of the pixel driving transistor of the pixel driving circuit 141 to form a pixel electrode of a specific color, such as a red pixel electrode or a green pixel electrode. , or blue pixel electrodes.

The display material layer 130 includes a hole transporting layer (HTL) 131, an emission layer 133, and an electron transporting layer (HTL) 135. The organic light-emitting diode layer 130 preferably generates red, blue, and green primary colors, so that the primary colors of red, blue, and green can be generated without using a conventional color filter.

FIG. 11 is another schematic diagram of one of the present inventions for displaying an inline display touch structure 900 with a data line as a transparent touch sensing connection. The main difference from FIG. 3 is that the cathode layer 910 is aligned with the anode layer 920. The cathode layer 910 has a plurality of cathode pixel electrodes 911. Each cathode pixel electrode 911 corresponds to a pixel driving transistor of the pixel driving circuit 141 of the thin film transistor layer 140, that is, each cathode pixel electrode of the plurality of cathode pixel electrodes corresponds to The pixel driving circuit The pixel/source 1415 of the pixel drive transistor of 141 is connected to form a pixel electrode of a specific color, such as a red pixel electrode, a green pixel electrode, or a blue pixel electrode.
