Abstract:
A liquid crystal display device having a uniform display screen from which a liner luminance defect which looks like a "seam" is eliminated. When, for example, one conductive or dielectric layer is exposed as shown in the figure, a total of four photomasks (60) corresponding to four shot areas (a, b, c and d) are used. For example, the light shielding layer (62) of the photomask used for exposure at the time of patterning a signal line (51) is so formed that the layer (62) is the projected pattern of the signal line (51). In addition, the photomasks corresponding to the adjacent shot areas, for example, the masks (a and b) are so formed that the patterns of light shielding layers (62) are fitted into each other like a finger joint at the boundary of the areas (a and b).
Abstract:
Provided is a COA substrate, comprising a glass substrate (1), a common electrode (2), an insulating layer (3) covering the common electrode (2), data lines (4) provided on the insulating layer (3) and staggered relative to the common electrode (2), and a first passivation layer (5), an RGB color resist layer (6), and a second passivation layer (7) that are sequentially provided on the data lines (4). A separation opening (14) is provided on the common electrode (2) at the position where the common electrode is staggered relative to the data lines (4), such that the common electrode (2) forms two opposite end portions. The insulating layer (3) fills the opening (14). A conductive layer (8) is provided on the second passivation layer (7) and is used for bridging the two end portions of the common electrode (2). Further provided is a liquid crystal panel, comprising the COA substrate. Compared with the prior art, the present invention reduces the parasitic capacitance generated between the data lines (4) and the common electrode (2) by increasing the spacing between the common electrode (2) and the data lines (4), thereby reducing the capacitive coupling effect of the data lines (4) on the common electrode (2), and avoiding the occurrence of crosstalk.
Abstract:
The present invention relates to a method of forming a pattern on a substrate and a method of manufacturing a liquid crystal display panel using the same. In order to decrease stitch defect, the shot boundary lines for respective layers of patterns do not overlap each other to be dispersed. Specifically, according to a method of forming patterns of the present invention, after a first material layer is first formed on a substrate, a first pattern is formed by performing a first photo etching including divisional light exposure with at least two areas across at least one shot boundary line on the first material layer. Subsequently, after a second material layer is formed on the first pattern, a second pattern is formed by performing a second photo etching including divisional light exposure with at least two areas across at least one shot boundary light on the second material layer. The shot boundary line in the second photo etching is spaced apart from the shot boundary light in the first photo etching. A liquid crystal display panel is manufactured by using this forming method.
Abstract:
In a method of manufacturing a liquid crystal display using a divisional exposure for a substrate, an overlapping area at the boundary between adjacent shots is provided and the shots left and right to the boundary are exposed in a way that the areas of the shots gradually decreases and gradually increases, respectively, to reduce the brightness difference due to stitch errors between the two shots. For example, the number of unit stitch areas assigned to the left gradually decreases and the number of unit stitch areas assigned to the right shot gradually increases as it goes to the right along the transverse direction in the stitch area. A unit stitch includes an area obtained by dividing a pixel into at least two parts.
Abstract:
A physical layout for a circuit using amorphous metal non-linear resistors as active devices for an in-plane switching liquid crystal display sub-pixel is provided. The lower interconnect of the two amorphous metal non-linear resistors and the lower electrode of the storage capacitor may be concurrently deposited and patterned. The area of the storage capacitor is defined by the overlap of the data signal interconnect and the storage capacitor lower electrode, which is easily modified through the size of the lower electrode and/or the size of the data signal interconnect where it overlaps the lower electrode and does not degrade the aperture ratio of the pixel. Two embodiments of sub-pixel circuits are described. One, which employs a select line bridge, enables the use of full dot inversion of the image data. The second only allows row inversion of the image data.
