INTRODUCTION TO THE INVENTION (The present invention generally relates to the configuration of a message relay for a display device and in particular relates to a system for adding a luminance signal to pixels of a display device such as a liquid crystal display (LCD). Such as a liquid crystal display The display devices are composed of a pixel matrix or array arranged horizontally and horizontally and vertically and vertically. The tube shadow information to be displayed is added to the data line as a brightness (grayscale) signal. These data lines are individually related to Each pixel is associated with a vertical line. These pixel horizontal lines are sequentially scanned and the capacitors of the pixels in the active horizontal line are charged to different degrees according to the brightness signal level added to the individual vertical lines. You can add to the pixel The brightness information of the array is made into the format of the μ brightness information signal generated by the M parallel brightness information transmission wire, for example, M = 100. These M brightness information signals are added to the input port of the input demultiplexer of the array. During each horizontal line time interval of the video signal, the demultiplexer converts these M luminance information signals into M × N parallel wires. The generated μχν signals, these MXN signals are driven to the μχν vertical wires connected to the array via the MXN data line. This input demultiplexer can be composed of MXN thin film transistors (TFT, S). In the video signal During each horizontal line interval, groups of M parallel wires are continuously selected to print conductors by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The selection of each group of M parallel wires is selected from the selection pulses generated by the bus of N parallel wires. Wave signal is obtained. The capacitance of the input message transfer path structure associated with N selected parallel wires and the input message transfer path structure associated with M free information transmission parallel wires can be regarded as power loss and yield loss. An important source of both, especially in the case of effective matrix liquid crystal displays (AMLCDs) with higher image quality and automatic scanning.

Description of the invention (4) The signals DWS (i) are all samples of 100 signals DWS (j) in a corresponding group in the control capacitor C43. To provide an effective time meter, a two-stage pipeline cycle can be used. The operation of the pulse wave signal DWS (i) demultiplexes the signal DBS (j) and stores it in 2400 capacitors C43. Then, the information in the capacitor C43 is simultaneously transferred to the shell material line driver 100. In this way, the capacitor Cm can demultiplex the next horizontal information and make it ready for use, and apply the previous horizontal information to these pixels. In addition to the message transfer path configuration described later, for example, the circuit of FIG. 2 can also be the same as that described in US Patent No. 5,673,063, which belongs to SHERMANi. The name is Signal to the data line driver of a display ". A feasible message transfer path configuration of the wires dw ("and DB (j) is described in the manner of Fig. 2. The message transfer of the wires DW (i) and DB (j), which embodies an invention feature, is described below. The path configuration is explained in the same way as in Fig. 3. The same symbols and numbers in Figs. I, 2 and 3 indicate the same items or functions. As explained above, the input message transfer path structure and wires DW (i) and DB (j) Associated crossover capacitors can be regarded as the main source of both power consumption and yield loss, especially for higher-quality effective matrix liquid crystal displays (AMLCDs). Long-term metal operation and multiple crossovers on the display More (source / drain metal to gate-metal) will cause significant capacitive load, resulting in two kinds of capacitive short circuit failure, no need to flee in the middle of the luminance information transmission wire, and excessive dynamic power consumption. The configuration of the message transfer path of 3 will reduce the correlation with this kind of message transfer path structure. _ 7 _ This paper size applies Chinese National Standard (CNS) A4 ^ T (21〇x 29f 公 爱) | ------- --------- (Please read first (Notes on the back page to write on this page) Order-Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 519612 A7 Printed by the Employee Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of Invention (5) In this way, the power consumption is reduced and the output is improved. In the message transfer path configuration of FIG. 2, all the wires DW⑴ that generate the gate signal Dw⑴ of the multiplexer transistor MN1 are connected to the message transfer path. -Connected to the entire display or globally. Each vertical row of the array is associated with the corresponding transistor drawing, and the gate electrodes of the two crystals must be connected to each other through a corresponding extension DWC (i) One of those message transfer path wires. Connecting the extension wire DWC (i) to the position closest to the data scanner transistor MNIL corresponding to the message transfer path wire DW (i) is not prepared to cause excessive capacitive problems. However, , When the completion of connecting a known ^ extension ^ line DWC⑴ to the corresponding message transfer path conductor farthest from the data scanner transistor Mm, its meaning is The extension wires ㈣⑴ must cross all other message transfer path wires DW (0) to which it is connected. This will cause the capacitive ballast CP to bleed with other wires, as shown in Figure 2 Disadvantageously, the number of each capacitive crossover increases geometrically with the number of data text wires DW (1) according to the following equation: Number of crossovers = number of brightness information transmission wires DB 传输 χι / 2χ ( The number of data word wires DW (i)). It can be said that the ideal way is to reduce the number of times the wire jumps, cross the wire barrel, reduce dynamic power consumption and improve productivity.

Inventory Note (6), instead of individually and evenly arranged on the display, grouped together to form a bureau. For example, for example, the luminance information transmission wires DB (丨) to DB (4) ° couple such clustered luminance information transmission wires DB (1) to DB (4) to four transistors MN1, which have The gates all share the data word wire DW (24). In this example, the number of crossings of the luminance information transmission wire DB (i) and the data word wire DW (i) has been reduced by a factor of 421. This advantageously reduces dynamic power consumption, improves yield, and reduces falsification between transmission lines of brightness information. In the configuration of FIG. 2, the transistors MN1 associated with the adjacent vertical rows of matrix 16 to 24 of FIG. 1 are all controlled by the continuous data word signal DWS (i) and a common signal DBS (i) is added to the corresponding vertical row. Gate. In comparison, in the configuration of FIG. 3, the transistor MN1 that is associated with the adjacent vertical row of the matrix 16-4 in FIG. 1 has the data word signal DW (24) used by it and 4 different signals DBS (i). To the gate corresponding to the vertical row. This cluster message transfer path configuration will add many new local sub-array DBSAs to the bus structure. Although these new local sub-arrays do add some additional crossovers to themselves (2.5 / brightness information transfer wires), this is because the average brightness information transfer wires and data word wire matrix crossover will average from 20 The / data line is reduced to only a small price of 5 / data line. With this message transfer path technology, the total capacitive coupling in the input message transfer path structure is reduced by a factor of four. For example, in a display with 100DB (j) and 24DW (i), when the message transfer path technology of FIG. 2 is used, the total number of crossovers is 28,800, while the cluster message transfer path of FIG. 3 only This gives a total of 7450 crossovers. -9- This paper size is in accordance with the Chinese National Standard (CNS) A4 (21 × 297 mm).
