Description
本創作係有關於一種觸控顯示裝置，特別是指一種主動式觸控顯示裝置。
The present invention relates to a touch display device, and more particularly to an active touch display device.
隨著現今科技蓬勃發展，電子消費商品種類推陳出新，滿足了大眾不同的需求。由於液晶顯示裝置（Liquid Crystal Display，LCD）具有輕薄短小與低耗電量等優點，而傳統顯示裝置具有體積大與高耗電量，因此，現今市面上，由液晶顯示裝置取代傳統映像管顯示裝置，而成為目前顯示裝置市場的主流。隨著資訊技術、無線行動通訊和資訊家電的快速發展與應用，為了達到更便利、體積更輕巧化以及更人性化的目的，許多資訊產品的輸入裝置已由傳統輸入裝置，例如:鍵盤或滑鼠等，轉變為使用觸控顯示裝置的觸控面板(Touch Panel)作為輸入裝置，同時也因為觸控顯示裝置的便利性讓消費性電子裝置為現今最流行的產品類型，例如:智慧型手機、攜帶式影音播放器(MP4)、數位相框、平板電腦等消費性電子裝置。
現今觸控顯示裝置的觸控面板大致可區分為電容式觸控面板、電阻式觸控面板與感光式觸控面板等類型，由於電容式觸控面板的精確度較電阻式觸控面板高，又電容式觸控面板的成本較感光式觸控面板低，因此讓採用電容式觸控面板之觸控顯示裝置蔚為主流。一般觸控顯示裝置之設置方式為將觸控面板設置於顯示面板上，以讓觸控面板依據觸控顯示裝置顯示之畫面提供可觸控區域，供使用者依據畫面所顯示之影像物件進行觸控操作，也就是，使用者可藉由手指或可觸控物而直接碰觸觸控顯示裝置的顯示畫面，以輸入使用者欲執行之觸控顯示裝置所提供的各項功能，因此簡化使用者在觸控顯示裝置的輸入操作複雜度。
請參閱第一圖，其為習知觸控顯示裝置之電路圖。如圖所示，習知觸控顯示裝置100包含一觸控基板110、複數檢測電極線111、複數控制電極線112、複數開關單元113、複數感測電極114、一彩色濾光層120、一遮光層121、一觸控驅動電路130與一觸控檢測電路140。遮光層121設置於彩色濾光層120上，觸控基板110設置於遮光層121上，而檢測電極線111、控制電極線112、開關單元113與感測電極114設置於觸控基板110上。檢測電極線111與控制電極線112於觸控基板110上交叉排列，且檢測電極線111與控制電極線112分別耦接該些開關單元113，控制電極線112耦接至觸控驅動電路130，檢測電極線111耦接至觸控檢測電路140。
習知觸控顯示裝置100係由觸控驅動電路130經控制電極線112驅動開關單元113，並藉由感測電極114感測觸控物(例如觸控筆或手指)，而產生一觸控訊號，感測電極114所輸出之觸控訊號經已驅動之開關單元113與檢測電極線111傳送至觸控檢測電路140，以檢測受觸控的位置。如此習知觸控顯示裝置100藉由上述之作動方式提供觸控功能，但，習知觸控顯示裝置100之檢測電極線111與控制電極線112跨越遮光層121與彩色濾光層120之部分透光區域，且檢測電極線111與控制電極線112一般為不透光之金屬材料，因而導致觸控顯示裝置100之透光率降低，所以造成觸控顯示裝置100需提高光源亮度，以維持顯示畫面的顯示亮度。
有鑑於此，本創作提出一種主動式觸控顯示裝置，其改善習知觸控顯示裝置之透光率問題，因而進一步增加觸控顯示裝置的透光率。
With the rapid development of today's technology, the variety of electronic consumer goods has been updated to meet the different needs of the public. Since the liquid crystal display (LCD) has the advantages of lightness, shortness, and low power consumption, and the conventional display device has a large volume and high power consumption, the conventional image tube display is replaced by a liquid crystal display device on the market today. The device has become the mainstream of the current display device market. With the rapid development and application of information technology, wireless mobile communication and information appliances, in order to achieve more convenience, lighter weight and more humane purposes, many information products input devices have been replaced by traditional input devices such as keyboard or slide. The mouse, etc., has been transformed into a touch panel using a touch display device as an input device, and because of the convenience of the touch display device, the consumer electronic device is the most popular product type today, for example, a smart phone. Consumer electronic devices such as portable audio and video players (MP4), digital photo frames, and tablet computers.
The touch panel of the touch display device can be roughly classified into a capacitive touch panel, a resistive touch panel, and a photosensitive touch panel. Since the accuracy of the capacitive touch panel is higher than that of the resistive touch panel, The cost of the capacitive touch panel is lower than that of the photosensitive touch panel, so that the touch display device using the capacitive touch panel is mainstream. Generally, the touch display device is disposed on the display panel, so that the touch panel provides a touchable area according to the image displayed by the touch display device, so that the user can touch according to the image object displayed on the screen. Control operation, that is, the user can directly touch the display screen of the touch display device by means of a finger or a touch object to input various functions provided by the touch display device to be executed by the user, thereby simplifying the use The input operation complexity of the touch display device.
Please refer to the first figure, which is a circuit diagram of a conventional touch display device. As shown in the figure, the touch display device 100 includes a touch substrate 110, a plurality of detection electrode lines 111, a plurality of control electrode lines 112, a plurality of switching units 113, a plurality of sensing electrodes 114, a color filter layer 120, and a The light shielding layer 121 , a touch driving circuit 130 and a touch detection circuit 140 . The light shielding layer 121 is disposed on the color filter layer 120, the touch substrate 110 is disposed on the light shielding layer 121, and the detecting electrode line 111, the control electrode line 112, the switch unit 113, and the sensing electrode 114 are disposed on the touch substrate 110. The detecting electrode line 111 and the control electrode line 112 are arranged on the touch substrate 110, and the detecting electrode line 111 and the control electrode line 112 are respectively coupled to the switch unit 113. The control electrode line 112 is coupled to the touch driving circuit 130. The detecting electrode line 111 is coupled to the touch detection circuit 140.
The touch display device 100 drives the switch unit 113 via the control electrode line 112, and generates a touch by sensing the touch object (such as a stylus or a finger) by the sensing electrode 114. The touch signal outputted by the sensing electrode 114 is transmitted to the touch detection circuit 140 via the driven switch unit 113 and the detection electrode line 111 to detect the touched position. The touch display device 100 provides the touch function by the above-described operation. However, the detection electrode line 111 and the control electrode line 112 of the touch display device 100 span the portions of the light shielding layer 121 and the color filter layer 120. The light-transmitting area, and the detecting electrode line 111 and the control electrode line 112 are generally opaque metal materials, thereby causing the light transmittance of the touch display device 100 to decrease, so that the touch display device 100 needs to increase the brightness of the light source to maintain Displays the display brightness of the screen.
In view of this, the present invention proposes an active touch display device that improves the light transmittance of the conventional touch display device, thereby further increasing the light transmittance of the touch display device.
