Description of the invention: ' [Technical field of invention] 'A touch technology' especially refers to a touch-controlled flat panel display that can directly sense the touch points of a flat panel display. [Prior Art] According to the vigorous development of high-tech electronic information industry, consumer electronic products have become a necessity in people's daily life, and many consumer electronic products have moved toward a trend of light, short, and small, especially in combination with display and The touch-sensitive liquid crystal display panel with two technologies has the functions of liquid crystal display and touch input, and can greatly improve the practical performance of various consumer electronic products. Please refer to FIG. 1 for a schematic diagram of a conventional touch-type liquid crystal display panel. As shown in the figure, the touch-sensitive liquid crystal display panel 1 mainly has a liquid crystal panel η and a touch panel 12. The surface of the liquid crystal panel 或 (or the touch panel 12) is covered with optical glue, and then the touch panel 12 (or the liquid crystal panel 11) is attached to the optical adhesive, and the button is pressed and added. After the light is mixed, the assembly of the mobile liquid crystal display panel 1 is completed. When the touch-type liquid crystal display panel 1 is in use, the liquid crystal panel η has a dedicated display driving circuit, and the touch panel 12 also needs a dedicated touch position analysis circuit. In addition, an associated driving circuit is required to be touched. The control position is integrated with the liquid crystal display position so that when the touch panel 12 is touched, the liquid crystal panel displays the corresponding action in real time. However, it can be found that the touch-type liquid crystal display panel 1 requires two types of panels, that is, the 3 201015400 touch panel 11 and the liquid crystal panel 12 are combined. Therefore, when the liquid crystal panel 12 located on the bottom layer is illuminated, the light will be The light-emitting efficiency of the touch-type liquid crystal display panel 1 is lowered by the touch panel n, and the thickness of the touch-type liquid crystal display panel j is also effectively reduced. The main reason is that at least two different panel stacks are required. Made. Furthermore, the touch panel 12 of different technical types, such as resistive or capacitive, has different touch position analysis circuits. Therefore, the touch-type liquid crystal display panel only corresponds to a technical touch panel. 12' is not easy to work with the display driver of the liquid crystal panel u. In addition, each type of touch panel 12 has its own missing when used or manufactured, for example, a resistive touch panel 12' When the temperature is limited by the ambient temperature, the temperature is too high, the temperature is too low, or the temperature difference is large, it is easy to affect the accuracy of the touch position judgment, and the resistive touch panel 12 is not easy to develop toward a large size; For example, the capacitive touch panel 12' is susceptible to the surrounding electric field and the gradation during use, resulting in a decrease in the accuracy of the touch position. At the same time, the capacitive touch panel 12 must use the finger as a source of contact, and cannot Think of using a general stylus, and you can't enter it by hand. © [The liquid crystal display and its touch method] can be used directly by the LCD panel of the Republic of China, such as the Republic of China Patent Gazette, Bulletin No. 1245252. The liquid crystal panel structure, and the thin film transistor liquid crystal display is respectively measured when the neutral time of the image data (or signal) written by the scan & line scan, that is, the transistor corresponding to the scan line is turned off (10)) The liquid crystal capacitance effect between the opposite electrode and the scanning line (_Hne), and according to the liquid crystal capacitance effect of each scanning line, it is judged whether the liquid crystal display of the liquid crystal display is touched, if it is touched Then, the voltage signal is injected into 201015400. After each data line ♦, the liquid crystal capacitance effect between the counter electrode and the data line is measured separately, and then the liquid crystals of the sample and the squall line are detected (4). The capacitive effect is large or changes to determine the wear point (coordinate) on the screen, so that the function of the touch screen can be achieved. Miscellaneous county to change the current LCD sulfur structure, but when there is touch on the full LCD panel, in addition to the need to detect the signal of the scan line and the signal line at the same time, it must provide an additional -f pressure, and then The electrician's number is measured by the capacitance effect of the leg test. Therefore, the patent is designed in circuit design. Therefore, in addition to the driving circuit of the liquid crystal panel and the circuit for touch analysis, an additional circuit for providing the voltage signal is required. When the liquid crystal panel is continuously touched, the power consumption is increased. Furthermore, the patent case must be scanned at the scan line to write the image data (or signal) at the time of the mark, and the touched lining 'scan line _ is time secret, so if there is some slight touch under continuous motion, It is easy to cause misjudgment, and if the scan line is written in the data, it will not be able to effectively determine the position of the touch. ❹ Further, as in the Republic of China Patent Gazette, Bulletin No. 1245253 [Touch-type liquid crystal display and touch method thereof], the present invention is characterized in that the structure of a ready-made thin film transistor liquid crystal display is scanned in its scanning line When I write the image data (signal), I (Idle Time) inputs an AC signal to the 〇pp〇site electrode, so that the AC signal is respectively (c〇uple) to the pair. The liquid crystal capacitor formed on the data line (a Une) and the scan line on the electrode and the thin film transistor (hereinafter referred to as TFT) substrate, when the liquid crystal display panel is pressed, the pressure point is corresponding Zilin and Zixin Chihe have a large face. Later, the relative position (coordinate) of the data line and the scan line of the 201015400 coupling signal is detected, and the film can be used to achieve the screen of the transistor liquid crystal display. The pressure point position (coordinate) on the basis, according to the function of the touch screen. However, this patent case is like the announcement number No. _52. In addition to the need to use the external wheel to transmit the signal 'Don', the slot time of the image data can be judged by the neutral time of the image data, and the scanning line is ❹ ❹ Short, so in the continuous action, the material touches a little, it will cause misjudgment, if the scan line "when it is connected to the Jew, there will be no financial touch touch position. Win the right [invention] Touch-type flat panel display = the above requirements, this person carefully studied, and accumulated many years of experience in the individual's career, the final design of the new invention - the purpose, to provide - directly The "touch type flat display" which is displayed on the plane and controls the position and the touch force. Another object of the present invention is that the touch surface of the fc·+ touch-type flat panel display can be directly used for the touch position and the touch force path _ and _4 methods on the flat display. The purpose of the re-purpose is to provide a flat-panel display of the waveform changes of the existing waveforms of the waveforms, such as touch positions and butterflies, and (four) displays. The other purpose of the rhyme is to provide a "touch-surface display" that can improve the waveform variation of the Bolin transmission. 201015400 In order to achieve the above object, the present invention relates to a touch panel display having a flat two display 'which can be a Thin Film Transistors Uquid Cystal Display (TFT LCD), a plasma display, an E-Paper or Active-Matrix liquid such as low temperature polycrystalline celestial liquid crystal panel

The controller continuously senses the waveform signals of the broom components on the first substrate, the second substrate and the test body to form a first-capacitance effect and a -first-resistance effect. The component read signal maintains a particular shape in accordance with the first capacitive effect and the first resistive effect. When the first substrate of the flat display is touched by an external force, the first substrate at the touch position will generate - greater than the first capacitance effect and the second resistance effect, the second capacitance reduction - the first The second resistance effect, the second capacitance effect and the second resistance effect cause the scanning elements to generate the waveform change (_fQrm dlfferenee) due to the RC delay (rc(4)) when transmitting the waveform signal, the spectrum change, the waveform slope peak Between the size and the scale of the scales, _, _ control _ occupation of the new frequency of the signal, the waveform signal without waveform changes for analysis, supplemented by the touch position of the material, the analysis of the scanning elements of the touch 2 Position the touch position and press the pressure track. In order to make the first substrate touch, the second capacitance effect 201015400 can be effectively increased, which can be performed by: changing the flexibility of the first substrate. More than the second substrate; changing the thickness of the first substrate to be smaller than the second substrate; and changing the Young's modulus of the first substrate to be smaller than the second substrate; The distance between the substrate and the second substrate is fixed. Therefore, when the flexibility of the first substrate is greater than the thickness of the second substrate, the thickness of the first substrate is smaller than the second base φ plate, or the Young substrate of the first substrate The amount of deformation of the first substrate is smaller than that of the first substrate, and the distance between the first substrate and the second substrate is increased, so that the second capacitance effect is small. The amount of change with this second resistance effect is significantly increased. In addition to the above, the amount of change in the second capacitance effect can be increased by the latter method. Before describing the second capacitive effect, first, the first substrate and the second substrate fine structure will be described. The first substrate and the second substrate are respectively provided on the surface of the liquid layer/transparent electrode layer (Indium Tin) Oxide, IT0), and the first substrate and the second substrate are connected by a plurality of spacers s_r), and the two ends of the spacers respectively support the transparent electrode layer on the surface of the first substrate and the second substrate And a color matrix layer (10) Resin) of the first substrate and the transparent electrode, and a black matrix between the color resist layer and the first substrate (Black)

When the flat panel display 2 is touched by an external force, the first substrate 21 of the touch point 4 is shaped like a dome. This deformation is not a gorge, and the deformation amount is small for the thick and thin flat panel display 2. It has become extremely large, and the surface of the first base (four) is deformed. Then, the distance between the second substrate 22 and the liquid layer 23 is shortened, resulting in an increase in capacitance and resistance effect. The effect and the second resistance effect, and the second capacitive effect and the second resistance effect cause the scanning element 24 to generate the waveform change due to the resistance delay hysteresis when transmitting the waveform signal, and the controller 3 changes according to the waveform , such as spectrum change, waveform shape change, waveform slope, rise time or peak size, etc., detect and locate the touch position and press pressure track. Moreover, different touch powers, and similar _ touch points 42, 42, which cause the change of the first substrate 21 to be different, which is more clearly seen in "Fig. 9", 14 201015400 right Pressing the flat panel display 2 from the left to the right with the same force, each pressing point is that each picture, electric 281, 282, 283, 284, 285 is pressed from left to right, then "9th picture" is obtained. As a result, it is apparent from the figure that the waveform change amounts of the respective pixel capacitors 281 to 285 are significantly different, and the waveform change amounts are different, and the position at the same force level pressing can be obtained by using these waveform change amounts. From the "1Qth diagram", the elastic deformation curves of the 'th-substrate 21' are not $, but even the same one is the same capacitance. The effect and the second resistance effect are also different. Therefore, the controller 3 only needs to change according to the waveform of the standby scanning element 241, such as spectrum change, waveform shape change, waveform slope, rise time or peak size, and can perform multiple touches. The position of the handle 4 is judged and the force is judged. Please refer to FIG. 11 for a block diagram of still another preferred embodiment of the present invention. The difference between this embodiment and the aforementioned "second diagram" lies in the use of the "second diagram". The scanning elements 24 are arranged in a single axis, that is, in a longitudinal or lying-to-direction setting, and in this embodiment t', the scanning elements 24 (10) can be arranged in a double sleeve manner, that is, the scanning elements 2 and 24 are respectively connected. The driving component 261 is configured to be criss-crossed in the plane display pirate 2 and connected to the controller 3 at the same time. When the flat panel display 2 is touched, the measurement result by the dual-axis sensing can be obtained. Make adjustment calculations to improve the accuracy of sensing the touch position and pressing the pressure track. In addition, the _Miao component 24 242 is a scan line and a signal line, respectively, meaning that the scan element 241 is a scan, a line, and is connected to the drive element 26, the scan element 242 is connected to the signal line. The driving element 262 is opposite to the scanning line 242 and is connected to the driving element 262. The scanning element 241 is connected to the driving element 261 by a signal line to 15 201015400.
