Abstract
Description
本創作係關於觸控板之技術領域,尤指一種高感測靈敏度的互電容內嵌式觸控顯示面板裝置。The present invention relates to the technical field of touch panels, and more particularly to a mutual-capacitance in-cell touch display panel device with high sensing sensitivity.
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,故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。而且直接疊合觸控面板以及平面顯示器時,將增加觸控面板本身之厚度,因而降低了光線的穿透率,增加反射率與霧度,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 superimposed touch panel display image. Then use the touch panel as the medium or interface for input. However, this conventional technique requires a large increase in the weight of the flat panel display due to the necessity of adding a complete weight of the touch panel, which does not meet the requirements of the current market for light, thin, short, and small displays. Moreover, when the touch panel and the flat display are directly stacked, the thickness of the touch panel itself is increased, thereby reducing the transmittance of light, increasing the reflectance and the haze, and 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)製作在顯示面板彩色濾光片(Color Filter,CF)的背面(即貼附偏光板面),整合為彩色濾光片的結構。On-Cell Touch的技術亦可將觸控面板的Sensor作在薄膜上,然後貼合在最上層的上基板的玻璃上。In Cell技術則是將感應電極(Sensor)置入LCD Cell的結構當中。然而,當感應電極置入LCD Cell結構後,由於感應電極與共通電壓層的距離僅有幾微米,因此彼此之間的電容量巨幅驟增,而觸碰的電容變化與之相比微乎其微難以偵測,且距離接近導致源自顯示訊號的干擾更為嚴重。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 color filter (CF) of the display panel (that is, the surface of the polarizing plate is attached), and is integrated into the structure of the color filter. The On-Cell Touch technology also allows the touch panel's Sensor to be placed on the film and then attached to the glass of the uppermost upper substrate. In Cell technology puts the sensor into the structure of the LCD Cell. However, when the sensing electrode is placed in the LCD Cell structure, since the distance between the sensing electrode and the common voltage layer is only a few micrometers, the capacitance between each other is greatly increased, and the capacitance change of the touch is relatively small. Detection, and proximity is more serious, resulting in more interference from the display signal.
圖1係一習知單層觸控面板的透明電極結構之 示意圖。如圖1所示,一透明電極結構11經由一走線12以將該透明電極結構11感應到的電氣訊號輸出。圖1的單層透明電極結構可實現真實多點觸碰偵測。於使用時,圖1的單層透明電極結構會與一顯示面板組合。然而單層觸控面板整合入顯示面板內時,該單層透明電極結構會與顯示面板的一共通電壓層之間形成顯著電容,且容易引起雜訊,而降低了偵測觸碰位置之準確度。目前市售之In Cell觸控面板為了解決電容與雜訊難以克服之窘境,通常是切割共通電壓層且以金屬線串接以形成單層互電容結構,或是切割共通電壓層後再外加一層透明接收電極層,前述切割共同電壓層的技術都必須與顯示控制分時操作,不但限制了觸控螢幕的解析度與尺寸,影響顯示品質且大幅增加顯示驅動控制電路之設計、調適與面板製造難度,以致生產良率降低,成本上升。因此,習知互電容內嵌式觸控顯示面板實仍有 予以改善的空間。1 is a transparent electrode structure of a conventional single-layer touch panel schematic diagram. As shown in FIG. 1, a transparent electrode structure 11 is output via a trace 12 to the electrical signal sensed by the transparent electrode structure 11. The single-layer transparent electrode structure of Figure 1 enables true multi-touch detection. In use, the single layer transparent electrode structure of Figure 1 will be combined with a display panel. However, when the single-layer touch panel is integrated into the display panel, the single-layer transparent electrode structure forms a significant capacitance with a common voltage layer of the display panel, and is easy to cause noise, thereby reducing the accuracy of detecting the touch position. degree. In order to solve the dilemma that capacitors and noise are difficult to overcome, the commercially available In Cell touch panel usually cuts the common voltage layer and connects the wires in series to form a single-layer mutual capacitance structure, or cuts the common voltage layer and then adds a layer. The transparent receiving electrode layer, the above-mentioned technology for cutting the common voltage layer must be operated with the display control time division, which not only limits the resolution and size of the touch screen, but also affects the display quality and greatly increases the design, adjustment and panel manufacturing of the display driving control circuit. Difficulty, resulting in lower production yields and higher costs. Therefore, the conventional mutual capacitance in-cell touch display panel still has The space to be improved.

When touch sensing is detected, the touch The control sensing circuit generates a transmission signal (TX) through the touch signal driving circuit and applies the same to the anode layer 970 to serve as a touch transmitting electrode, and receives the touch by the plurality of receiving sensing electrodes 171. Control signal. The display layer 930 is an organic light emitting diode layer. FIG. 11 is a schematic diagram of a stacking of another embodiment of a high-sensitivity mutual-capacitance in-cell touch display panel device 1100. The main difference between FIG. 11 and FIG. 10 is that, in FIG. 11, the red light-emitting layer 933-1, the blue light-emitting layer 933-2, and the green light-emitting layer 933-3 are used, so that it is not necessary to use a color filter and A black matrix.
由前述說明可知,本創作使用共通電壓層、陰 極層、或是陽極層兼作為互電容感測技術中的發射電極(TX electrode),當進行觸控偵測時,該共通電壓層、陰極層、或是陽極層會有觸控驅動發射訊號(TX signal),且經過該共通電壓層、陰極層、或是陽極層與複數個接收感應電極171之間的互感應電容(Cm)耦合至該複數個接收感應電極171,該觸控感應控制電路620經由量測該複數個接收感應電極171,而獲得該等觸控感應訊號。因此本創作技術無需切割共通電壓層、亦無需與顯示控制分時操作,故不會有習知觸控螢幕的解析度與尺寸被限制的問題。同時為避免施加於該共通電壓層160之觸控發射訊號(TX)干擾顯示面板,又將顯示控制電路610和觸控感應控制電路620及觸控訊號驅動電路630的電源與接地分開,故不會干擾顯示畫質。It can be seen from the foregoing description that this creation uses a common voltage layer and a negative The pole layer or the anode layer also serves as a transmitting electrode (TX electrode) in the mutual capacitance sensing technology. When the touch detection is performed, the common voltage layer, the cathode layer, or the anode layer may have a touch driving transmission signal. (TX signal), and the mutual sensing capacitance (Cm) between the common voltage layer, the cathode layer, or the anode layer and the plurality of receiving sensing electrodes 171 is coupled to the plurality of receiving sensing electrodes 171, and the touch sensing control The circuit 620 obtains the touch sensing signals by measuring the plurality of receiving sensing electrodes 171. Therefore, the creation technique does not need to cut the common voltage layer, and does not need to perform time-sharing operation with the display control, so there is no problem that the resolution and size of the conventional touch screen are limited. The touch control signal (TX) of Can interfere with the display quality.
