Abstract: The present invention relates to a touching-type electronic paper and method for manufacturing the same. The touching-type electronic paper includes a TFT substrate and a transparent electrode substrate which are disposed as a cell. The transparent electrode substrate includes a common electrode, microcapsule electronic ink and light guiding poles as light transmitting passages, all of which are formed on a first substrate. The TFT substrate comprises displaying electrodes, first TFTs for driving the displaying electrodes, second TFTs for detecting lights transmitting through the light guiding poles and for producing level signals, and third TFTs for reading the level signals and sending the level signals to a back-end processing system, all of which are formed on a second substrate. The light guiding poles are opposite to the second TFTs respectively. The present invention makes the natural lights or other lights outside transmitted to the second TFTs through the light guiding poles by disposing the light guiding poles as light transmitting passages and disposing the second TFTs as light sensor units. The present invention has many advantages such as simple structure, simple manufacturing process and low cost, so as to have a wide application prospect.

Abstract translation: 触摸式电子纸及其制造方法技术领域本发明涉及触摸式电子纸及其制造方法。 触摸型电子纸包括作为单元设置的TFT基板和透明电极基板。 透明电极基板包括公共电极，微胶囊电子墨水和作为透光通道的导光柱，所有这些都形成在第一基板上。 TFT基板包括显示电极，用于驱动显示电极的第一TFT，用于检测通过导光极传输的光的第二TFT和用于产生电平信号的第三TFT，以及用于读取电平信号并将电平信号发送到后端的第三TFT 处理系统，它们都形成在第二基板上。 光导极分别与第二TFT相对。 本发明通过将导光柱设置为透光通道，并且将第二TFT设置为光传感器单元，使外部的自然光或其它光通过导光杆传输到第二TFT。 本发明具有结构简单，制造工艺简单，成本低等优点，具有广泛的应用前景。
