Description
本創作係關於一種具有觸控板的顯示螢幕之結構，尤指一種以顯示資料線作為觸控感應連接線之內嵌顯示觸控結構。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.
現代消費性電子裝置多配備觸控板做為其輸入裝置之一。觸控板根據感測原理的不同可分為電阻式、電容式、音波式、及光學式等多種。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.
習知之觸控式平面顯示器係將觸控面板與平面顯示器直接進行上下之疊合，因為疊合之觸控面板為透明之面板，因而影像可以穿透疊合在上之觸控面板顯示影像，再藉由觸控面板作為輸入之媒介或介面。然而這種習知之技藝，因為於疊合時，必須增加一個觸控面板之完整重量，使得平面顯示器重量大幅地增加，不符合現時市場對於顯示器輕薄短小之要求。而直接疊合觸控面板以及平面顯示器時，不但增加觸控面板本身之厚度，且降低了光線的穿透率，還增加了反射率與霧度，使螢幕顯示的品質大打折扣。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.
針對前述之缺點，觸控式平面顯示器改採嵌入 式觸控技術。嵌入式觸控技術目前主要的發展方向可分為On-Cell及In-Cell兩種技術。On-Cell技術是將投射電容式觸控技術的感應電極(Sensor)製作在面板彩色濾光片(Color Filter,CF)的背面(即貼附偏光板的表面)，將感應電極整合到彩色濾光片的結構中。In-Cell技術則是將感應電極(Sensor)置入LCD Cell的結構當中，主要利用的感應方式也可分為電阻(接觸)式、電容式與光學式三種，其中電阻式是利用LCD Cell上下兩基板電極的導通，計算電壓分壓的變化來判定接觸位置座標，On-Cell Touch的技術則是先將觸控面板的Sensor做在薄膜上，然後貼合在第一基板的玻璃上或直接將Sensor用透明導電材料做在基板上。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.
而Out Cell Touch技術是將觸控面板外掛在顯示 面板上，是目前最常見的形式；電阻式、電容式等技術都有，通常都是由另外的觸控面板廠商製造，再與顯示面板進行貼合與組裝。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技術則是將觸控元件整合於顯示 面板之內，使得顯示面板本身就具備觸控功能，因此不需要另外進行與觸控面板貼合或組裝的製程，這樣技術通常都是由面板廠開發。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.
然而不論In-Cell Touch技術、On-Cell Touch技 術、或Out Cell Touch技術，皆在顯示面板的上玻璃基板或下玻璃基板設置透明導電材料(ITO)的感應電極層，不僅增加成本，亦增加製程程序，容易導致製程良率降低及製程 成本飆昇，且因開口率下降而須要更強的背光，而增加耗電，不利於行動裝置低功耗的需求。因此，習知的觸控顯示面板結構仍有改善的空間。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.
本創作之主要目的在提供一種以顯示資料線作為觸控感應連接線之內嵌顯示觸控結構，可大幅節省材料成本及加工成本；因為無需於顯示面板的上玻璃基板或下玻璃基板設置透明導電材料(ITO)的感應電極層，據此可降低成本，減少製程程序。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.

圖9係本創作之以顯示資料線作為觸控感應連 接線之內嵌顯示觸控結構100的使用示意圖，其係使用於一液晶顯示器中。如圖9所示，係包含一資料處理單元910、一顯示控制單元920、一觸碰偵測單元930、一時序控制單元940、一種以顯示資料線作為觸控感應連接線之內嵌顯示 觸控結構100、複數個顯示開關950、一資料傳送器960、及一閘極驅動器970。在本實施例中，該以顯示資料線作為觸控感應連接線之內嵌顯示觸控結構100係具有顯示及觸控功能。其中，部分之該複數條資料線420分別連接至複數個顯示開關950，以當進行觸碰偵測時，部分之該複數條資料線420電氣連接至一觸碰偵測單元930，當非進行觸碰偵測時，部分之該複數條資料線420電氣連接至一資料傳送器960。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.
於圖9中，由於本創作係以顯示資料線作為觸 控感應連接線，該感應導體區塊520-1的觸控感應連接線，以傳輸該感應導體區塊520-1所感應的電氣訊號。因此，當閘極驅動器970驅動掃描線320-1以進行影像顯示、且觸碰偵測單元930對該感應導體區塊520-1執行觸碰偵測時，與該資料線420-1連接之該顯示開關950進行切換，以優先將該資料線420-1電氣連接至該觸碰偵測單元930，俾執行自電容觸碰感應偵測。故掃描線320-1與資料線420-1交會處的子像素區顯示資料會產生錯誤。然而，此僅有一個子像素區的資料錯誤。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.
當閘極驅動器970驅動掃描線320-2以進行影像 顯示、且觸碰偵測單元930對該感應導體區塊520-2執行觸碰偵測時，與該資料線420-2連接之該顯示開關950進行切換，以優先將該資料線420-2電氣連接至該觸碰偵測單元930，俾執行自電容觸碰感應偵測。於此同時，與該資料線420-1連接之該顯示開關950進行切換，以將該資料線420-1電氣連接至該資料傳送器960。故僅掃描線320-2與資料線 420-2交會處的子像素區顯示資料會產生錯誤。然而，此僅有一個子像素區的資料錯誤，並不影響整個顯示影像的品質。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.
由前述說明可知，本創作的該感應導體區塊 520-1可包含上百個子像素區530，上百個子像素區530中僅有一個子像素區530會因觸碰感應偵測而受影響。然而一個full HD高畫質液晶顯示器中其至少有6220800(1920x1080x3)個子像素區，即使幾百個不連續的子像素區530受影響，人類眼睛亦無法察覺，因此並不影響整個顯示影像的品質。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. .

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.
