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.

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 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. On-Cell technology is to cast capacitive touch The sensing electrode of the control technology is formed on the back surface of the upper substrate with respect to the color filter (CF) (that is, the surface of the polarizing plate is attached), and is integrated into a color filter. In-Cell technology puts the sensing electrode into the structure of the LCD Cell. The main sensing methods currently used can be divided into three types: resistance (contact), capacitive and optical. Resistive type uses LCD Cell. The upper and lower substrate electrodes are turned on to calculate the change of the partial pressure to determine the contact position coordinates. On-Cell Touch's technology is to apply the sensor of the touch panel to the film and then attach it to the glass of the uppermost upper substrate.

The Out Cell Touch technology refers to the external plug-in display panel. The external touch panel is also the most common one at present. Resistive and capacitive technologies are usually manufactured by other touch panel manufacturers, 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 TFT LCD panel factory.

However, regardless of In-Cell Touch technology, On-Cell Touch technology Or Out Cell Touch technology, which is provided with a sensing electrode layer on the upper glass substrate or the lower glass substrate of the LCD display panel, which not only increases the cost, but also increases the process procedure, which easily leads to a decrease in process yield and a rise in process cost, and an opening A lower rate of backlighting requires a stronger backlight, which also increases power consumption, which is detrimental to the thin and light requirements of mobile devices. Therefore, there is still room for improvement in the conventional touch display panel structure.

The main purpose of this creation is to provide a display data line As an in-line display touch structure of the touch sensing connection line, the material cost and the processing cost can be greatly saved; since the sensing electrode layer of the transparent conductive material (ITO) is not required to be disposed on the upper glass substrate or the lower glass substrate of the display panel, Reduce costs and reduce process procedures.

According to one of the characteristics of this creation, this creation proposes a display The data line serves as an in-line display touch structure of the touch sensing connection line, and includes a first substrate, a second substrate, a thin film transistor layer and a 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 surface of the second substrate opposite to 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 based on a first The direction (X) is set, and the plurality of data lines are set according to a second direction (Y). The sensing electrode layer is located on a surface of the thin film transistor layer on one side of the display material layer, and has a plurality of sensing conductor segments, the plurality of sensing conductor segments being according to the first direction (X) and the second direction (Y) setting, the plurality of sensing conductor segments are electrically connected to form a plurality of sensing conductor blocks; wherein a portion of the plurality of data lines are electrically connected to the plurality of sensing conductor blocks respectively to transmit the plurality of sensing The electrical signal sensed by each of the inductive conductor blocks of the conductor block.

In this embodiment, it is assumed that there are m+1 columns (Row), so the sensing conductor blocks 370-(mN+1), ..., 370-(mN+N) of the last column are respectively connected by the data line 320- (mN+1), ..., 320-(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.

As shown in FIG. 3 and FIG. 5, in this embodiment, a preferred choice is made. The data line 320-1 of the red sub-pixel area 360-1 is electrically connected to the sensing conductor block 370-1 to transmit the electrical signal sensed by the sensing conductor block 370-1.

In other embodiments, the data line 320-1 can also be expanded. width. When the width of the data line 320-1 is expanded, one method is to reduce the red sub-pixel area 360-1. 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 approach is to increase the spacing of the red sub-pixel region 360-1 from its left green sub-pixel region 360-3 to accommodate the wider data line 320-1.

The first substrate 110 and the second substrate There is a common electrode layer between 120.

Figure 6 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. 6 , it includes 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. 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 320 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 320 are electrically connected to a touch detection unit 930. During the touch detection, a portion of the plurality of data lines 320 are electrically connected to a data transmitter 960.

In Figure 6, since the creation department uses the display data line as the The touch sensing connection line of the sensing conductor block 370-1 transmits the electrical signal sensed by the sensing conductor block 370-1. Therefore, when the gate driver 970 performs image display by driving the scan line 310-1, and the touch detection unit 930 performs touch detection on the sensing conductor block 370-1, it is connected to the data line 320-1. The display switch 950 switches to preferentially connect the data line 320-1 to the touch detection unit 930 to perform self-capacitance touch sensing detection. Therefore, an error occurs in the display of the sub-pixel area at the intersection of the scan line 310-1 and the data line 320-1. However, there will only be a data error in one sub-pixel area.

When the gate driver 970 drives the scan line 310-2 to perform image Display, and touch detection unit 930 performs touch on the sensing conductor block 370-2 During the touch detection, the display switch 950 connected to the data line 320-2 is switched to preferentially electrically connect the data line 320-2 to the touch detection unit 930, and perform self-capacitance touch sensing detection. . At the same time, the display switch 950 connected to the data line 320-1 is switched to electrically connect the data line 320-1 to the data transmitter 960. Therefore, only the sub-pixel area at the intersection of the scan line 310-2 and the data line 320-2 may display 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 inductive conductor block of the present creation The 370-1 may include hundreds to thousands of sub-pixel regions 360, and only one of the sub-pixel regions 360 of the hundreds of sub-pixel regions to the thousands of sub-pixel regions 360 may be affected by the touch sensing detection. However, in a Full HD high-definition liquid crystal display, there are at least 6220800 (1920×1080×3) sub-pixel areas, and even if hundreds of discontinuous sub-pixel areas 360 are affected, the human eye cannot detect it, and thus does not affect the quality of the entire display image. .

Figure 7 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. 6 is that the touch detection unit 930, the plurality of display switches 950, and the data transmitter 960 are integrated into an integrated circuit. Meanwhile, when the touch sensing detection is performed, the touch detecting unit 930 simultaneously drives/detects a column of the sensing conductor blocks 370-1, 370-2, ..., 370-N to improve the touch detection return rate ( Report rate), N is an integer greater than one. After the touch detection of the inductive conductor blocks 370-1, 370-2, ..., 370-N of one column is completed, the touch detection unit 930 drives/detects the sensing conductor blocks of the next column.
