Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display, and more particularly to a touch liquid crystal display. [Prior Art] Liquid crystal display is one of the best display modes because of low power consumption, miniaturization, and high-quality display. At present, the more commonly used liquid crystal display is a TN (Twisted Nematic) mode liquid crystal display (TN_LCD). For TN-LCD, when no voltage is applied to the electrode, the day and night crystal display is in the 〇FF state, and the light energy is transmitted through the liquid crystal display; when the voltage is applied to the electrode, the liquid crystal display is in the “LCD display”. (10)" state, the long-axis direction of the liquid crystal molecules is arranged in the direction of the electric field, and the light cannot pass through the liquid crystal display, so the state. Selectively applying a voltage ' on the electrodes can show a different pattern. Brain display factory, crying Γ 'With the mobile phone, touch navigation system, integrated electric hair: 7 in the high-performance of various electronic devices and the display surface of the diversified sub-screen display the potential of the touch screen: touch Two: Plus. The user of the electronic device can visually confirm the display content of the liquid crystal display by using the touch screen, and the operation of the liquid crystal display can be operated by using the touch screen. Thus, Zhang, the crystal display screen of the various functions of the electronic device. Often divided into four types, upper = rational: different transmission media, through the surface acoustic wave. 4 two capacitive inductive and infrared type electric touch screens are widely used due to their high resolution, high sensitivity and durability of 201003200. However, prior art resistive touch screens typically include an indium tin oxide layer (ITO layer) as a transparent conductive layer prepared by ion beam sputtering or steaming, Kazuhiro Noda et al. in the Production of
Transparent Conductive Films with Inserted Si02 Anchor Layer, and Application to a Resistive Touch Panel (Electronics and Communications in Japan, Part 2, Vol.84, P39-45(2001))中介紹了一種採用IT0/Si02/聚對苯二甲酸 乙二醇酯層的觸摸屏。該ITO層在製備的過程，需要較高 的真空環境及需要加熱到200〜30〇t：，故，使得採用IT0 作爲透明導電層的觸摸屏的製備成本較高。此外，先前技 術中的ITO層作爲透明導電層具有機械性能不够好、難以 弓曲及阻值分佈不均勻等缺點’不適用於柔性的觸摸式液 晶顯示屏中。另，ITO在潮濕的空氣中透明度會逐漸下降。 從而導致先前的職屏及使用，摸屏的觸摸式液晶顯示 屏在耐用性不够好，靈敏度低、線性及準確性較差等缺點。 有鑒於此’提供-種具有耐用性好、靈敏度高、線性 及準碟性强的觸摸式液晶顯示屏實為必要 【發明内容】Transparent Conductive Films with Inserted Si02 Anchor Layer, and Application to a Resistive Touch Panel (Electronics and Communications in Japan, Part 2, Vol. 84, P39-45 (2001)) describes the use of IT0/SiO 2 / polyparaphenylene Touch screen of ethylene glycolate layer. In the preparation process, the ITO layer requires a high vacuum environment and needs to be heated to 200 to 30 〇t: Therefore, the preparation of the touch panel using IT0 as a transparent conductive layer is relatively expensive. In addition, the prior art ITO layer as a transparent conductive layer has disadvantages such as insufficient mechanical properties, difficulty in bowing, and uneven distribution of resistance values, and is not suitable for use in a flexible touch liquid crystal display. In addition, ITO will gradually decrease in transparency in humid air. As a result, the previous screen and use of the screen, the touch screen liquid crystal display screen is not good enough in durability, low sensitivity, linearity and poor accuracy. In view of the above, it is necessary to provide a touch-type liquid crystal display having high durability, high sensitivity, linearity and quasi-disc property.
