實施例一 Embodiment 1

本發明第一實施例提供一種觸控顯示裝置。如第1圖所示,所述觸控顯示裝置包含:第一基板11;第二基板13,配置為與第一基板平行;液晶層15,設置於第一基板11與第二基板13之間;以及多個觸摸感應電極17,所述多個觸摸感應電極17設置於第一基板11的下表面,並且排列成二維陣列。 A first embodiment of the present invention provides a touch display device. As shown in FIG. 1 , the touch display device includes: a first substrate 11 ; a second substrate 13 disposed parallel to the first substrate; and a liquid crystal layer 15 disposed between the first substrate 11 and the second substrate 13 And a plurality of touch sensing electrodes 17 disposed on the lower surface of the first substrate 11 and arranged in a two-dimensional array.

所述多個觸摸感應電極17排列成的二維陣列可以是矩形陣列或其他類似形狀的二維陣列。所述觸摸感應電極的形狀可以是正多邊形(例如正方形)、長條形、圓形、橢圓形或三角形等。所述觸摸感應電極17的邊緣上還可以有鋸齒。 The two-dimensional array in which the plurality of touch sensing electrodes 17 are arranged may be a rectangular array or a two-dimensional array of other similar shapes. The shape of the touch sensing electrode may be a regular polygon (for example, a square), a strip shape, a circle shape, an ellipse shape, a triangle shape, or the like. The touch sensing electrode 17 may also have serrations on the edge.

優選地,所述多個觸摸感應電極17的材料是金屬氧化物,例如氧化銦錫(ITO)。 Preferably, the material of the plurality of touch sensing electrodes 17 is a metal oxide such as indium tin oxide (ITO).

對於電容式觸控式螢幕來說,每個觸摸感應電極是一個電容感測器,所述電容感測器的電容在螢幕上相應位置被觸摸時發生變化。採用排列成二維陣列的多個觸摸感應電極,實現了多點觸控。進一步來說,在現有技術的顯示觸控式螢幕中,觸摸感應電極由行電極和列電極組成,每行或列上的雜訊會疊加。例如,多個手指放到同一行或列,各手指感應的電源雜訊會在同一行或列上疊加。手指越多,則疊加的雜訊越大。而在本實施例所提供的顯示觸控式螢幕中,觸摸感應電極(即,觸摸感應階段的觸摸感應電極)排列成二維陣列,每個電極只是陣列中的一個單元,單元間互不干擾。每行或列包含不同的矩陣單元,不會造成雜訊的疊加。因此,本發明的觸控 顯示裝置顯著減少了最大雜訊的幅度,提高了訊噪比。 For a capacitive touch screen, each touch sensing electrode is a capacitive sensor whose capacitance changes when the corresponding position on the screen is touched. Multi-touch is achieved by using a plurality of touch sensing electrodes arranged in a two-dimensional array. Further, in the prior art display touch screen, the touch sensing electrode is composed of a row electrode and a column electrode, and noise on each row or column is superimposed. For example, if multiple fingers are placed in the same row or column, the power noise detected by each finger will be superimposed on the same row or column. The more fingers there are, the larger the noise is superimposed. In the display touch screen provided by the embodiment, the touch sensing electrodes (ie, the touch sensing electrodes in the touch sensing stage) are arranged in a two-dimensional array, and each electrode is only one unit in the array, and the units do not interfere with each other. . Each row or column contains different matrix elements and does not cause a superposition of noise. Therefore, the touch of the present invention The display device significantly reduces the amplitude of the maximum noise and improves the signal to noise ratio.

所述觸控顯示裝置還可以包含觸控晶片19,所述觸控晶片19綁定到第一基板11的下表面,並且與所述多個觸摸感應電極17之中的每一個分別通過導線相連接。所述觸控晶片19可以通過玻璃覆晶(Chip-on-Glass)方式綁定到第一基板11的下表面。 The touch display device may further include a touch wafer 19 bound to a lower surface of the first substrate 11 and respectively passed through a wire phase with each of the plurality of touch sensing electrodes 17 connection. The touch wafer 19 may be bonded to the lower surface of the first substrate 11 by a chip-on-glass method.

由於與每個觸摸感應電極17分別通過導線相連接,觸控晶片19的管腳很多,因此,將觸控晶片19綁定到第一基板11上能夠避免以往封裝的困難,以及管腳數量多可能造成的晶片體積增加和封裝成本提高。而且,藉由例如COG的方式綁定,觸控晶片18與第一基板11成為一體,與現有技術中通過柔性電路板(FPC)連接觸控晶片和觸控式螢幕相比,減小了整體的體積。此外,由於觸摸感應電極一般藉由在基板上對導電層(例如ITO等金屬氧化物,或金屬)進行蝕刻形成,而觸控晶片也位於基板上,因此,兩者之間的連線可通過一次導電層蝕刻完成,簡化了製造工序。 Because each of the touch sensing electrodes 17 is connected by wires, the touch wafer 19 has many pins. Therefore, binding the touch wafer 19 to the first substrate 11 can avoid the difficulty of the conventional packaging and the number of pins. Possible wafer volume increase and packaging cost increase. Moreover, the touch wafer 18 is integrated with the first substrate 11 by means of, for example, COG bonding, which is reduced compared with the prior art in which the touch chip and the touch screen are connected by a flexible circuit board (FPC). volume of. In addition, since the touch sensing electrode is generally formed by etching a conductive layer (such as a metal oxide such as ITO or a metal) on the substrate, and the touch wafer is also located on the substrate, the connection between the two can be passed. The etching of the conductive layer is completed once, which simplifies the manufacturing process.

This The voltage difference between the detected electrode and the non-detection electrode can be reduced, which is advantageous for reducing the capacitance of the detected electrode and preventing false touches formed by water droplets.

另外,對於每個觸摸感應電極17而言,所述觸控晶片19可以在驅動所述觸摸感應電極17的同時,根據驅動當前觸摸感應電極17的訊號來驅動所述觸控顯示裝置的顯示模組的公共電極,從而減少觸摸感應電極17和公共電極間的電容,提高電容的相對變化量,從而提高訊噪比。 In addition, for each touch sensing electrode 17, the touch control chip 19 can drive the display mode of the touch display device according to the signal driving the current touch sensing electrode 17 while driving the touch sensing electrode 17. The common electrode of the group reduces the capacitance between the touch sensing electrode 17 and the common electrode, and increases the relative variation of the capacitance, thereby improving the signal-to-noise ratio.
