[Prior Art] The touch panel is used to be combined with a flat display device, so that the peripheral computer device such as a button or a mouse can be used to perform an instruction, because the computer is 7旳勖As the flat panel display, which is gradually becoming a function of touch panel technology, has also been introduced, it has become a hot electronic product in the market today. The conventional touch panel can be composed of an upper conductive layer and a lower conductive layer. The capacitive touch panel is taken as an example. The method is disposed on the lower surface of the substrate, wherein the upper conductive layer surface can be arranged in a plurality of flat layers. On the upper conductive electrode, the number of sub-numbers is relatively negative! ·H " The surface of the lower conductive layer can be formed with a conductive electrode below the electric electrode, and the conductive electrode of the vertical and vertical is formed to form a uniform lightning power W m Electric cymbal, which can change the weak current of the human finger to achieve a touch effect. In the early days, the touch panel was produced by the company, and it was only produced after the completion of the touch panel. Further, a pair of touch panels for splicing and squeezing the size of the field are provided, and the combination of the touch panels can be adhered to the surface of the flat display. Because the surface is not visible, such as LCD display crying Meng Shishi Yiwen is limited to the strong ambient light intensity and the difference in the quality of the visibility quality, when the touch panel is directly set on the 4 M334968 flat panel display, will be serious Reflection, the overall reflectivity can be as high as 25 / °, resulting in a strong external environment illumination, the user can not clearly view the image from the light surface of the touch & flat panel display. In order to improve the image visibility under strong light, the general touch-type flat display does not use a light polarization principle to add a polarizer inside, so that the polarization characteristics of the external light source can be utilized to make the polarized light The film absorbs and damages the external light source to reduce the reflection. Although this method can improve the light reflection, in the actual φ, the light that is not absorbed by the polarizer will also be from the lower layer of the flat display. When the structure is reflected back, even if an anti-reflection film is added, the problem of the first layer reflection can be improved, and the light-emitting efficiency of the flat display can be affected. Therefore, there is also a related industry to increase the brightness of the display design, in order to improve this - phenomenon, # including the optimal design of the lamp and light guide, improve the J rate, increase the party film or other polymer materials to enable the backlight Efficiently being used, and even injecting liquid helium into the middle of the touch panel and the display, depending on the above-mentioned methods, there is power consumption, poor reliability, complicated process _ special defects, and common disadvantages are expensive. At present, the touch-type flat panel display solves the problem of external light source reflection, and the original transmissive liquid crystal panel adopts a semi-reflective and semi-transparent liquid crystal surface. = 'When placed in an environment with strong external interference light source, the reflectivity will be Compared with the penetration rate, the external light source can be effectively utilized to increase the overall brightness, so that the X display quality is better (the external light utilization rate is about 10% or more). However, the reflection interference of the touch surface itself still exists, and the function of the semi-reflective semi-transparent liquid crystal panel using the external light source to increase the brightness is weakened due to the fact that the touch panel itself will counteract the 'original' of the touch panel itself, so that the overall display device is weakened. Can not achieve the better display 5 M334968 夤, therefore, the current touch _ can improve the anti-reflection work of the surface display design still to be improved [new content] Feng anti: (5) for the purpose of providing a kind of anti-reflective capacitive touch Control + shooting: the tooth-to-surface display device 'except for the flat surface with touch function is not light and thin, can also be left to the left, and then shoot, effectively convert the light into the light surface of the panel screen. The brightness is provided to provide the user with a clear development picture 'to reduce the influence of ambient light on development and improve visibility. The technical means used for the purpose of the invention is that the anti-reflective capacitive touch semi-reflective semi-transmissive flat display device comprises: a semi-reflective half-teeth liquid crystal display panel comprising a thin film transistor substrate semi-transparent a semi-reflective sheet' - a liquid crystal layer and an upper substrate, the semi-transmissive semi-reflective sheet and the liquid crystal layer are disposed between the thin film transistor substrate and the upper substrate, wherein the film is disposed under the surface of the crystal substrate a circular polarizer; and a capacitive touch panel disposed on the upper substrate of the semi-reflective semi-transparent liquid crystal display panel, which mainly includes a conductive layer from the bottom to the top, a substrate, an upper conductive layer, a phase difference plate, a polarizing plate, and a first substrate, wherein an optical axis angle of the polarizing plate is angularly different from the phase difference plate, and an optical axis of the polarizing plate and the phase difference plate The angle is matched with the optical axis angle of the lower circular polarizer, and further, an anti-reflection film is disposed on the upper surface of the second substrate. The present invention may further comprise at least one intermediate conductive layer disposed between the upper conductive layer and the lower conductive layer to reduce electromagnetic interference between the upper conductive layer and the lower conductive layer 6 M334968. The present invention is to provide a phase difference plate and a polarizing plate between the second substrate of the capacitive touch panel and the upper conductive layer, and the phase difference plate can be a 1/4 λ phase difference plate, wherein the polarizing plate is The optical axis angle is optimally 45 degrees apart from the phase difference plate. It is also possible to add one or two layers of 1/4 phase difference plate to the optical design of the semi-reflective transflective liquid crystal display. According to the design requirements; in addition, the semi-reflective semi-transparent flat display device has a lower optical axis angle of the circular polarizer corresponding to the polarizing plate and the phase difference plate of the capacitive touch panel, which simplifies the touch-type semi-reflection. The semi-transmissive flat display device (the structure does not allow the touch panel to achieve the lowest self-interference reflectivity (3) / below), but also because the light enters the touch-type semi-reflective semi-transmissive flat display device The circular polarizer application cannot be directly reflected by the layers of the touch panel (interference reflection), and the incoming light is effectively reflected by the reflection mechanism formed in the semi-reflective semi-transmissive flat display (displaying the reflectivity of 15% or more), true = lower Touch half The interference reflection of the semi-transmissive flat display device, the touch-sensitive semi-reflective semi-transmissive flat display device displays the reflectivity, and the touch-type semi-reflective semi-transmissive flat display device effectively reflects the field under strong light illumination The light converted into the light-emitting surface of the LCD enhances the brightness of the light-emitting surface to provide a clear development picture for the user, reduce the shadow of the ambient light on the development, and improve the visibility.曰[Embodiment] First, please refer to the first touch semi-reflective semi-transparent plan.
