New description: [New technical field] This series is about the passive matrix liquid crystal display, especially the electrode layer in the passive matrix liquid crystal display panel. Tian Yi said that [previous technology] witnessed the existing liquid crystal flat panel display, according to its driving method classification, there are two types of passive matrix and active matrix, of which passive matrix type super twisted nematic liquid crystal flat panel display ( STN_LCD is the main one, while the active matrix type is mainly a thin film transistor liquid crystal flat panel display (TFT-LCD). The configuration of the super twisted nematic liquid crystal flat panel display is exemplified by a color super twisted nematic liquid crystal flat panel display panel, which mainly comprises a front panel portion, a rear panel portion, and is sealed between the front and rear panel portions. The liquid crystal, wherein the front (or rear) panel portion is mainly provided with a color filter, a transparent electrode layer and an alignment film on the inner side surface of a front glass substrate, and the liquid crystal is adjacent to the alignment film. A polarizer is disposed on the outer side of the front (or rear) glass substrate, and the rear (or front) panel portion is mainly provided with a transparent electrode layer and an alignment film on the inner side surface of the rear glass substrate, and the alignment is performed The film is adjacent to the liquid crystal, and a polarizer is disposed on the outer side of the rear (or front) glass substrate for providing a contiguous backlight module. The transparent electrode layer is patterned on the side of the front (or rear) glass substrate and the side of the color filter on the rear glass substrate. The patterns of the two transparent electrode layers are respectively transparent. The conductive film strips are arranged in parallel, and the transparent conductive strips of the front and rear transparent electrode layers are perpendicular to each other, and are respectively connected to the driving circuit of the liquid crystal display, thereby using the driving circuit to pass through the driving circuit. A voltage is applied between the two transparent electrode layers, the liquid crystal switch (〇n/〇ff) is controlled, the intensity of the light penetrating the panel is changed, and the color of the light passing through the color filter is displayed, thereby displaying a color image. The super twisted nematic liquid crystal flat panel display panel provides a display capable of displaying a picture, however, as shown in the fourth and fifth figures, the transparent electrode layer (4) disposed on the glass substrate (3) in the panel It consists of a plurality of parallel-stop transparent conductive posts (40) spaced in parallel, and the transparent conductive film strip (4 〇) is made of Indium ηη Oxide (IT0) material. It has both light transmissivity and electrical conductivity, but the indium tin oxide is still less conductive than silver, copper, gold and other metal materials, and its impedance value is high. When the transparent conductive film strips (4 〇) are close to each other钿 When the input voltage is conducted to the far end, the near-end and the far-end of the transparent conductive film strips (4 〇) cause a large difference in voltage value due to the high impedance value, which affects the torsional ability of the liquid crystal driving, resulting in uneven brightness of the panel. . [New content] The main purpose of this creation is to provide an electrode layer structure of a passive matrix liquid crystal display, and design 1 to solve the problem that the display screen is poor due to the large impedance value of the transparent conductive film strip in the existing transparent electrode layer. In order to achieve the foregoing objectives, the technical solution proposed by the present invention is mainly to ensure that the electrode layer structure disposed on the transparent substrate comprises a plurality of transparent conductive blocks and a plurality of metal conductive lines, and the transparent conductive blocks are arranged in a matrix. On the transparent substrate, the metal conductive lines are spaced apart from the transparent substrate M296386 and are respectively connected in series with one of the rows of transparent conductive blocks adjacent to each other to maintain a space between the adjacent transparent conductive blocks. The design of the present invention is mainly based on the design of the prior art, which mainly uses a matrix of transparent conductive blocks in the electrode layer, and another metal conductive wire with a lower resistance than the transparent conductive block is connected to the transparent conductive blocks. As the medium of the input voltage, # so that the voltage values of the near end and the far end of each transparent conductive block are nearly equal, so that the driving ability of the liquid crystal is driven to reduce the unevenness of the panel. In addition, the creation can further distribute the transparent conductive blocks to the visible red (R) green (G) blue (b) green patterns in the color filter (CF) of the liquid crystal display. The light-transmissive metal conductive line is hidden under the black matrix (βΜ) of the color filter (CF) so that it does not affect the optical characteristics, so that the liquid crystal display has an excellent image quality level.

Black matrix of the photoresist pattern (Black Matrix; BM) 〇 The transparent conductive blocks (20) may be formed by using indium tin oxide (IT〇) or an equivalent material thereof, and the metal conductive wires (2 1 ) are Selecting a conductive metal material (such as nickel, silver, aluminum, copper, silver, gold, etc.) whose impedance value is lower than the transparent conductive block (2 〇), and the metal conductive wires (2 1 ) The distance (D1) between the adjacent transparent conductive blocks (2 〇) is preferably about 2 μπι, and the distance between adjacent two transparent conductive blocks (2 〇) (D2) corresponds to the black matrix (Black Matrix). ; BM) width. When the electrode layer structure of the present invention is applied to a passive matrix liquid crystal display (STN LCD), a color passive matrix liquid crystal display panel is taken as an example, and each of the sides of the transparent substrate (1) is formed on the front side of the liquid crystal display panel. The electrode layer (2), the transparent conductive block (2 〇) of the front and rear two electrode layers (2) correspond to each other before and after, and the metal wires (2 1 ) 1 of the front and rear layers are vertically crossed and correspond to the color slab The black matrix 'is further connected to the driving circuit of the passive matrix liquid crystal display by the metal conductive lines 2 1 of the front and rear electrode layers (2), respectively, and the metal circuit M296386 is electrically connected by the driving circuit via the two electrode layers. (2 1) When a voltage is applied to the transparent conductive regions ^ ( 2 Q ), the liquid crystal switch (on/〇 ff) can be controlled, the intensity of the light penetrating the panel is changed, and the light is presented through the color filter.

The difference in voltage value makes the driving liquid crystal have the same torsion ability, which reduces the problem of uneven brightness and darkness of the panel. In addition, the transparent conductive blocks (2 〇) are distributed in the corresponding color filters (CF). The visible area of the green (()) blue (B) photoresist pattern, the opaque metal conductive lines are hidden under the black matrix (βΜ) of the color filter (CF), thus not affecting The optical characteristics make the 5H liquid crystal display have an excellent image quality level.
