Abstract

This invention relates to a multiplexing circuit for use with displays, where an image data source sequentially transmits n image element data to the multiplexing circuit, the multiplexing circuit having n corresponding output ports, where the nth output port is directly connected to the image data source and the remaining n1 output ports are each connected to the image data source through a thin film transistor. The thin film transistors are each activated via the control of timing trigger signals of the 1st to the n1th image element data so as to separately output the image element data. Since no thin film transistor is provided between the nth output port and the thin film transistor, there is an additional open space so that the thin film transistors of the multiplexing circuit can be made in accordance with a higher Width/Length parameter, thereby reducing the speed of working current drop to minimum working current due to internal stress and extending the lifespan of the component.

INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a multiplex circuit, and more particularly to a multiplex circuit for use in a display. [Prior Art] The display of i is mainly after receiving the display signal, and then sending a video data (Data) through a data line driving integrated circuit (ic), the image data is temporarily memorized in a pixel area. Show it. For the design of SOG (System on Glass), a TFT display using a_Si is taken as an example. Please refer to the ninth and tenth figures. The image contains two primary colors (Red-Green-Biue; rgb) images. The element data is separated into the pixel area by using a multiplexed circuit to separate the RGB image element data. In the actual application, if the data line driver 1C has m data lines, the mother data line is matched with one more. The component can be used to push the display of 3 m image element data. The multiplexed circuit is composed of three thin film transistors (M1 to M3), and has the same characteristics for each of the seven thin film transistors (Μ1 to M3), and the parameter of each of the thin film transistors (M1 to Μ3) per unit area. Both are 300Mm/5/xm (W/L), wherein the thin films of the thin film transistors (Μι~m3) are connected to the video processing ic to receive image data (Data), and the source system is used as the two primary colors. The output terminals (Cr, Cg, Cb) are matched with the timing of the RGB data in the image data, respectively. The thin film transistor (the gate is fed with a set of trigger signals (sR) (sG) (Sb) to be turned on. The thin film transistor (M1~M3), please refer to the tenth figure, for example, 3 200828206 When the image data (Data) is in the timing of the R data, the trigger signal is sent to the gate of the thin film transistor (M1) ( sR) turns on the thin film transistor (M1), so that the R data can pass from the thin film transistor (M1) and stop the sending of the trigger signal () to turn off the thin film when the timing of the data to be stored in the pixel region ends. Crystal (Μ1), and so on, can separate RGB data from image data. After the material (Data) transfer is completed, it also indicates that the RGB data has been separated from each other and temporarily stored in the pixel area. At this time, the display side starts to display the image screen. However, after the transistor element is used for a period of time, it should be inside the component. The shirting sound causes the Vu of the transistor component to shift and the conduction current decreases. Once the operating current is too low, the film can be successfully passed through the thin film, and the data temporarily stored in the halogen region is reduced. The above-mentioned multiplexed circuit is lost through the thin film transistor, and the above-mentioned multiplexed circuit is lost. [Inventive content] In order to solve the above-mentioned internal stress caused by the element (the problem of efficiency, the travel of the city is also lost, the main The purpose is to provide a multi-power data source for display.

According to the foregoing technical means, a thin film transistor is not provided between the source of the image data and the last end of the present invention, and a part of the facial enamel can be vacated, and the area of the pericardial transistor can be made more favorable. Large specification number (W/L); from the operating current formula of the transistor component "W^C〇x(w/L)(vgs-Vth)2/2]", if the specification of the transistor component ( If the fox is improved, the servo current will also increase. Therefore, when the thin film transistor is affected by the internal stress and the operating current is decreased, the higher operating current can prolong the working current to the minimum operating current. Reduce the possibility of multiplexed circuit failure. The multiplexed circuit of the present invention further includes a diode coupled between the image source and the output of the thin film transistor. Further, a Gamma adjuster is further disposed between the image data source and the multiplex circuit, and the Gamma adjuster is used to control the Gamma adjustment value of the image element data. The voltage value of the image element data is lower than the rest of the image. The voltage value of the element data.

To design a polar body (2 6 ) as: also, there is a phase: the capacitance (Cgs) drops (△), then you can write The strength balanced. 1 . One: Solution S is caused by the characteristics of the transistor, and the signal strength at the time of output is not overcome. The fifth embodiment of the present invention overcomes the hand slaves different from the foregoing fourth embodiment, and the fifth embodiment of the present invention substantially returns + The second principle of the circuit and the narration is mainly to adjust the image element to adjust the value of the image to reduce the glory of the glory, and the gamma of the snail. Among them: the output signal of the syllabus of the syllabus The image displayed by the device is processed by many pieces, and the photoelectric element of the 1 J characteristic is degraded. Therefore, the photocell components of different characteristics also have different characteristics of the _M & It is necessary to separately perform correction with different conversion curves of the 200828206 c; and the fifth embodiment of the present invention further provides a Gamnia adjuster between the original data (2 0 ) and the multiplex circuit (2 7 } 'The Gamma Tuner (2 7) adjusts the Gamma adjustment value of the third output signal (〇3) shirt image element data to be lower than the first and first output signals (01) (〇2) image The gamma of the elemental data is worth '7 to the vegan The voltage value of the third output signal (03) is lower than the voltage value of the first output signal (〇1) (〇2) by a difference (Δν), so that the fourth embodiment can be achieved. The effect of the signal strength at the output is balanced.
