[0065] 由于,线栅结构WG的周期宽度P实质等于或小于可见光的波长(例如,实质介于400纳米至800纳米)的二分之一。 [0065] Since the period of the width of the wire grid structure WG P substantially equal to or smaller than the wavelength of visible light (e.g., 400 nm between the substance to 800 nanometers) one-half. 因此,可将大部分平行线栅结构WG的光反射轴Xl (即平行导线104排列方向)振动的电场向量的光线加以反射,只容许垂直线栅结构WG的光反射轴Xl的电场向量的光线通过。 Thus, the electric field vector of light (i.e., parallel to the wire alignment direction 104) vibrating the light reflection axis parallel to the wire grid structure most Xl WG may be reflected to allow only the electric field vector of the light axis of the light reflected Xl vertical lines of the grid structure WG by. 故光学膜片100可用来作为一反射型偏光板。 Therefore, the optical film 100 may be used as a reflection type polarizer.

[0066] 由于光学膜片100同时又具有彼此邻近且相互绝缘的第一电极102和第二电极103,经过适当的图案设计,可作为触控面板的感测电极,在基材表面1la上定义出包含第一区域lOlal、第二区域101a2和第三区域101a3的触控区11a。 [0066] Since the optical film 100 but also has a first electrode adjacent to each other and insulated from each other 102 and the second electrode 103, with proper designs, can be used as the sensing electrodes of the touch panel, is defined on the substrate surface 1la a first region comprising the lOlal, the second region 101a2 101a3 and the third region of the touch area 11a. 在覆盖介电材质的保护层105,并与驱动电路及读取电路(未绘示)加以整合之后,即可构成一触控面板11 (请参照图2)。 Protective layer covering the dielectric material 105, and then the drive circuit and the reading circuit (not shown) to be integrated to form a touch panel 11 (see FIG. 2). 当手指触碰到触控面板11的触控区Ila的表面时,会影响第一电极102和第二电极103间的电场,因而改变由第一电极102和第二电极103所构成的电容结构的电容值,并借由探测电容值的改变定位出触碰点。 When a finger touches the touch surface of the touch panel 11 of the region Ila, it will affect the first electrode 102 and the electric field between the second electrode 103, thereby changing the capacitance of the structure constituted by the first electrode 102 and second electrode 103 the capacitance value of the touch point and positioned by means of detecting change in capacitance value.

[0067] 若将触控面板11与一显示介质,例如液晶面板,整合,即可构成一触控式液晶显示装置I。 [0067] If the touch panel 11 with a display medium such as liquid crystal panel, integrated to form a touch-sensitive liquid crystal display device I. 请参照图3,图3是根据本发明的一实施例所绘示的一种触控式液晶显示装置I的结构剖面不意图。 Referring to FIG. 3, FIG. 3 is an embodiment of the invention depicted a touch-type liquid crystal display device I is a cross-sectional structure is not intended. 其中,触控式液晶显不装置I包含一液晶面板10、一偏光板12、一面光源13以及触控面板11。 Wherein, does not touch the liquid crystal display device I comprises a liquid crystal panel 10, a polarizer 12, a surface light source 13 and the touch panel 11. 其中,液晶面板10具有一入光面1a和一出光面10b。 Wherein the liquid crystal panel 10 having a light incident surface 1a and an exit surface 10b. 液晶面板10的出光面1b与触控面板11的基材101平行设置。 The liquid crystal panel 10 of the touch panel surface 1b and the substrate 101 arranged in parallel 11. 例如,在本实施例中,触控面板11是以相对于基材101表面1la的另一表面1lb平行贴合于液晶面板10的出光面1b上。 For example, in the present embodiment, the touch panel 11 is with respect to the other surface of the base 101 parallel to the surface bonded 1lb 1la of the liquid crystal panel of an upper surface 1b 10. 面光源13,例如背光模块,面对液晶面板10的入光面1a,偏光板12位于面光源13与液晶面板10的入光面1a之间。 The surface light source 13, such as a backlit module, facing the surface 1a of the liquid crystal panel 10, a polarizer 12 is positioned between the inlet 13 and the liquid crystal panel surface 1a of the surface light source 10.
