Description of the invention (6) The drain of the membrane transistor is floating, The right-most pixel does not have a storage capacitor = β. Each pixel except the right-most pixel has two storage valleyrs, and the right-most pixel has a stray capacitor. In the liquid crystal display shown in circle 3, when a switching element such as a thin film transistor fails, the drain of the discharged thin film transistor Q0 can be cut with the liquid crystal capacitor by cutting the area I in FIG. 4 by using a laser or the like. In this case, the data capacitor is not applied to the pixel's liquid crystal capacitor. According to the charge transfer rule, the pixel voltage Vp of the liquid crystal capacitor of a pixel can be determined by the following formula — VP = (VL + VR + CLCXCst) / (2 + CLC / Cst) where VL is the pixel voltage of the left pixel, Vr is the image voltage of the right pixel, .cLC is the capacitance of the liquid crystal capacitor of the pixel, and Cst is the capacitance of the stray capacitor of the pixel a CLC / Cst is less than 1, and cLC / Cst increases with the increase of Cst However, the pixel voltage is close to the arithmetic mean of the left and right pixel voltages. Therefore, the illuminance of the pixel is close to the arithmetic mean of the illuminance of the left and right pixels, and the pixel defects are automatically compensated. , ’, Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs because the image brightness changes slowly except for the object boundary. This pixel lacks a good redundant structure, especially for monochrome display. As far as color display is concerned, the staggered capacitor can be connected to a third adjacent pixel, that is, a pixel that displays the same color as the defective pixel, to achieve the purpose of self-redundancy.

Description of Invention (9) 21 〇 Now, the operation of the aforementioned liquid crystal display will be described. First, a gate connection voltage is applied to the gate electrode 11 of the picture element to display a signal via the gate core line 10 to communicate the thin film transistor. A data voltage representing a display signal is applied to the source 61 via the data line 60, and the data voltage is transmitted to the drain 62 through the thin film transistor channel. The data voltage is transmitted to the pixel electrode 82, and an electric field is generated between the two substrates due to a voltage difference between the pixel electrode 82 and a reference electrode located on the opposite substrate. The amount of electric field is controlled by the large + of the data voltage, and the liquid crystal molecules are rearranged by the electric field to control the amount of light transmission. On the other hand, the direction of the electric field needs to be changed periodically to prevent the liquid crystal material from being damaged. That is, the polarity of the data voltage with respect to the f test voltage must be changed periodically. The aforementioned method is called a conversion-driven method. There are many types of conversion-driven methods, such as frame conversion, line conversion, point conversion, and line conversion. The frame switching driving method is to change the pixel voltage with respect to the reference voltage repeatedly using the frame as a unit. If it is a line conversion driving method, the polarity of the pixel voltage relative to the reference voltage is changed by using the gate line as a unit. If it is a point conversion driving method, the polarity of the pixel voltage relative to the reference voltage is based on the pixel as a unit. change. During a closed pole selection time, all pixels are individually charged to the applied data voltage. During the hold period, the pixel voltage is held until the subsequent data voltage is written. According to a specific example of the present invention, each pixel voltage is a reference voltage with respect to an adjacent stray capacitor. If it is a line or frame conversion method, adjacent pixels have the same voltage when they are displayed completely white or completely black, so the voltage difference between the two electrodes of the 'storage capacitor can be ignored.

The thick line indicates the fourth specific example of the present invention, and the dashed line indicates the case of the conventional common electrode structure. "The line indicates the case where there is no storage structure, and this line is not shown because it overlaps with the thick line. nest Within a period of time, all data voltages relative to a horizontal line are 10 volts (line conversion method).

The pixel voltage is compared with the common electrode structure and the structure without storage capacitor.

The pixel voltage of a conventional common-electrode liquid crystal display can be partially held by a storage capacitor, so that the pixel power does not decrease so quickly. In the fourth embodiment of the present invention, the pixel voltage in the liquid crystal display or the liquid crystal display without a storage capacitor structure decreases rapidly. The rapid decrease in the pixel voltage is caused by the same amount of leakage current, which makes the voltages of adjacent pixels simultaneously. Generates a decrease in pixel voltage.

INTRODUCTION OF THE INVENTION (11) Even if the pixel voltage of the pixel structure of the fourth specific example of the present invention is lower than that of the conventional common electrode structure, The cell voltage still drops more slowly than the pixels without storage capacitors. ♦ It is a dot conversion method, and the voltage changes of adjacent pixels are reversed, so the liquid crystal display of the suspected example of the present invention produces a more effective voltage holding capability, as shown in Figure ^. The specific example of the present invention has the best voltage holding capability. In the dot conversion method, the voltage of the odd data line is 10 volts, the voltage of the even data line is 1 volt ', and the liquid crystal resistance is 1 * 10u ohm. Figure 13 shows that the pixel voltage is shifted by the capacitive coupling to the gate voltage drop. The longer charging time of the specific embodiment of the present invention is due to the larger voltage difference between the storage capacitor electrode and the point conversion driving method. The kickback voltage Vkb of the liquid crystal display of the specific example of the present invention is larger than that of a conventional common electrode type pixel, and is the same as a pixel without a storage capacitor. The larger kickback voltage is due to the simultaneous voltage drop of adjacent pixels by coupling with the gate voltage drop. For failed pixels, as shown in Figure 4, the pixel calendar is determined by the voltage of adjacent pixels, as shown in Figure 14. The higher curve indicates the unit voltage on the left and the right, while the lower curve is the electric mill of the failed pixel.
