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

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

Modern consumer electronic devices are often equipped with a touchpad as one of their input devices. The touchpad can be divided into resistive, capacitive, sonic, and optical types according to different sensing principles.

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 conventional technique is required to increase the total weight of a touch panel when superimposing, so that the weight of the flat display is greatly increased, which does not meet the requirements of the current market for the lightness and thinness of the display. When the touch panel and the flat display are directly stacked, the thickness of the touch panel itself is increased, the light transmittance is reduced, and the reflectance and the haze are increased, so that the quality of the screen display is greatly reduced.

In response to the aforementioned shortcomings, the touch flat panel display is embedded and embedded. Touch technology. The main development direction of embedded touch technology can be divided into On-Cell and In-Cell technologies. On-Cell technology is to make the sensor of the capacitive touch technology (Sensor) on the back of the panel color filter (CF) (that is, the surface attached to the polarizer), and integrate the sensing electrode into the color filter. In the structure of the light sheet. In-Cell technology puts the sensor into the structure of the LCD Cell. The main sensing methods can be divided into three types: resistance (contact), capacitive and optical. Resistive type uses LCD Cell. The conduction of the two substrate electrodes, the change of the voltage partial pressure is calculated to determine the contact position coordinates, and the On-Cell Touch technology is to first apply the sensor of the touch panel to the film, and then attach it to the glass of the first substrate or directly The sensor is made of a transparent conductive material on the substrate.

Out Cell Touch technology is to attach the touch panel to the display. On the panel, it is the most common form at present; resistive and capacitive technologies are commonly used, and are usually manufactured by another touch panel manufacturer, and then assembled and assembled with the display panel.

In-Cell Touch technology integrates touch components into the display Within the panel, the display panel itself has a touch function, so there is no need to separately perform a process of bonding or assembling with the touch panel, and the technology is usually developed by the panel factory.

However, regardless of In-Cell Touch technology, On-Cell Touch technology Or Out Cell Touch technology, which is provided with a transparent conductive material (ITO) sensing electrode layer on the upper glass substrate or the lower glass substrate of the display panel, which not only increases the cost, but also increases the process procedure, which easily leads to process yield reduction and process The cost is soaring, and a stronger backlight is required due to a decrease in aperture ratio, which increases power consumption, which is not conducive to the low power consumption of mobile devices. Therefore, there is still room for improvement in the conventional touch display panel structure.

The main purpose of the present invention is to provide an in-line display touch structure with a display data line as a touch sensing connection line, which can greatly save material cost and processing cost; since it is not necessary to provide transparency on the upper glass substrate or the lower glass substrate of the display panel. The sensing electrode layer of conductive material (ITO) can reduce the cost and process process.

According to one of the features of the present invention, the present invention proposes an in-line display touch structure using a display data line as a touch sensing connection line, comprising a first substrate, a second substrate, a display material layer, a thin film transistor and 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 and the sensing electrode layer are located on a surface of the second substrate opposite to one side of the display material layer, and the thin film transistor and the sensing electrode layer have a scan line sublayer and a data line sublayer. The scan line sublayer has a plurality of scan lines and a plurality of first sense conductor segments. The plurality of scanning lines are disposed according to a first direction, and the plurality of first sensing conductor segments are disposed according to a second direction, and the plurality of first sensing conductor segments are separated by the plurality of scanning lines. The data line sublayer is located on a surface of the scan line sublayer on one side of the display material layer, and has a plurality of data lines and a plurality of second sensing conductor lines. The plurality of data lines are set according to the second direction, the plurality of lines The two sensing conductor segments are disposed according to the first direction, and the plurality of second sensing conductor segments are separated by the plurality of data lines.

In this embodiment, it is assumed that there are m+1 columns (Row), so the sensing conductor blocks 520-(mN+1), ..., 520-(mN+N) of the last column are respectively composed of data lines 420- (mN+1), ..., 420-(mN+N) extending downward, and further extending from the plurality of connecting lines 730 to one side 101 of the in-cell touch display panel structure 100 for further connection The touch control circuit 610 to a circuit board 600. The touch control circuit 610 can also be placed directly on the lower glass substrate in the design of different display panel structures.

As shown in FIG. 8, the inductive conductor block 520-1 includes 48 The pixel region 530 is only a schematic view. In an actual situation, the sensing conductor block 520-1 can include hundreds of sub-pixel regions 530. Meanwhile, the plurality of sensing conductor blocks 520 can form a touch detection plane.

As shown in FIG. 6 and FIG. 8, in this embodiment, a preferred choice is made. The data line 420-1 of the red sub-pixel area 530-1 is electrically connected to the sensing conductor block 520-1 to transmit the electrical signal sensed by the sensing conductor block 520-1.

In other embodiments, the data line 420-1 can also be expanded. width. When the width of the data line 420-1 is expanded, one method is to reduce the red sub-pixel area 530-1. At this time, the detected electrical signal can be detected by an electronic circuit such as a driving circuit inside the touch control circuit 610. Make adjustments and compensation. Another method is to increase the spacing of the red sub-pixel area 530-1 from the left green pixel area 530-3 to accommodate the wider data line 420-1.

Figure 9 is the creation of the data line as a touch sensing company. The schematic diagram of the use of the touch display structure 100 is embedded in the wiring, which is used in a liquid crystal display. As shown in FIG. 9 , a data processing unit 910 , a display control unit 920 , a touch detection unit 930 , a timing control unit 940 , and an inline display with a display data line as a touch sensing connection line are included. The 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 touch sensing connection line has a display and touch function. The plurality of data lines 420 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 420 are electrically connected to a touch detection unit 930. During the touch detection, a portion of the plurality of data lines 420 are electrically coupled to a data transmitter 960.

In Figure 9, because the creation department uses the display data line as a touch The sensing connection line is connected to the touch sensing connection line of the sensing conductor block 520-1 to transmit the electrical signal sensed by the sensing conductor block 520-1. Therefore, when the gate driver 970 drives the scan line 320-1 for image display, and the touch detection unit 930 performs touch detection on the sensing conductor block 520-1, it is connected to the data line 420-1. The display switch 950 switches to preferentially connect the data line 420-1 to the touch detection unit 930 to perform self-capacitance touch sensing detection. Therefore, the display of the sub-pixel area at the intersection of the scan line 320-1 and the data line 420-1 may cause an error. However, this data has only one sub-pixel area error.

When the gate driver 970 drives the scan line 320-2 for image When the display and touch detection unit 930 performs the touch detection on the sensing conductor block 520-2, the display switch 950 connected to the data line 420-2 is switched to preferentially select the data line 420-2. Electrically connected to the touch detection unit 930, the self-capacitance touch sensing detection is performed. At the same time, the display switch 950 connected to the data line 420-1 is switched to electrically connect the data line 420-1 to the data transmitter 960. Therefore, only scan line 320-2 and data line Displaying data in the sub-pixel area of the 420-2 intersection will generate an error. However, this data error of only one sub-pixel area does not affect the quality of the entire display image.

It can be seen from the foregoing description that the inductive conductor block of the present creation The 520-1 may include hundreds of sub-pixel regions 530, and only one of the hundreds of sub-pixel regions 530 may be affected by touch sensing detection. However, in a full HD high-definition liquid crystal display, there are at least 6220800 (1920×1080×3) sub-pixel regions. Even if hundreds of discontinuous sub-pixel regions 530 are affected, the human eye cannot detect it, and thus does not affect the quality of the entire display image. .

Figure 10 is the creation of the data line as a touch sensing company. Another schematic diagram of the use of the touch display structure 100 is embedded in the wiring. 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 row of sensing conductor blocks 520-1, 520-2, ..., 520-N to improve the touch detection. Return rate. After the touch detection of the columns of the inductive conductor blocks 520-1, 520-2, ..., 520-N is completed, the touch detection unit 930 drives/detects the sensing conductor blocks of the next column.
