Description

  The present invention relates to a method for arranging a light emitting region and a circuit region of a pixel, and more particularly to a method for arranging a light emitting region and a circuit region inside an active matrix display pixel in a stripe arrangement.

  The pixel arrangement method of the display includes a stripe shape, a mosaic shape, a delta shape, and the like.

  In the stripe arrangement, as shown in FIG. 1, red light (R), green light (G), and blue light (B) appear in the row direction, and are then overlapped in the column direction. The display method is obtained.

  In the mosaic arrangement, as shown in FIG. 2, red light (R), green light (G), and blue light (B) arranged in the row direction shift one pixel between each row, that is, the first column ( Column 1) and the second column (Column 2) are shifted from each other by a pixel that generates one light of the same color, and the second column and the third column are also shifted by a pixel that generates one light of the same color. The following is also inferred.

  In the delta arrangement, as shown in FIG. 3, the pixels R, G, and B are all shifted by 1.5 pixels (deviation 1.5 pixels), and the pixels of the same emission color are all shifted. This produces the effect of making the display screen uniform.

  In traditional active display designs, many of the arrangement methods are stripe arrangements, and such stripe arrangement methods are convenient, orderly, and easy to layout, so less complex layouts are required, so Widely applied to thin film transistor liquid crystal displays or thin film transistor organic light emitting displays. However, in order to simplify the layout by orderly matching, the transistor layout areas on the same column are laid out on the same straight line, and therefore the circuit layout area and the light emitting area are clearly divided, that is, currently in a stripe arrangement. The R, G, B pixel arrangement method is constructed on the layout base of a passive circuit (for example, the data line 11 and the scanning line 12), and the influence of the circuit region 14 and the light emitting region 13 is not considered. A known stripe arrangement is as shown in FIG. From this figure, it can be seen that the dark non-light emitting region formed by the circuit region 14 of each row pixel forms a clear dividing line on the display screen, which affects the quality of the display image on the display. .

  Therefore, a known striped display can easily form a zebra-shaped wrinkle in which the light-emitting area 13 and the non-light-emitting area (circuit area 14) are divided into bright and dark areas, thereby easily forming a clear division state on the screen display. In particular, when the area of the transistor or capacitor in the circuit region 14 increases, the situation where the display is divided by the circuit region 14 becomes severe. This arrangement is the simplest intuitively, and the display effect of the characters is very good, but the uniformity of the frame displaying the image cannot be achieved, the orderly stripe arrangement is easily perceived by the user's vision, The unlighted area is clearly recognized by the black shadow of the line ridge where the layout occurs.

  Also, the well-known delta arrangement or mosaic arrangement R, G, B pixel arrangement method does not consider the arrangement of the circuit area 14 and the light emitting area 13 in the same manner. To achieve uniformity by moving the R, G, and B pixels as a whole, that is, this method achieves uniformity of the display image by moving and adjusting the light emitting region 13 and the circuit region 14 together. Achieve. However, since pixels that generate the same color light are too far apart and two other color light pixels exist in the middle, a problem of unevenness occurs in displaying characters.

  The main object of the present invention is to eliminate the black dividing lines of an image by adopting a layout method of a stripe arrangement, so that a good image display effect can be obtained and a good character display capability can be maintained. There is to do.

  Another object of the present invention is to make it convenient for layout as a collinear line on a scanning line by adjusting the arrangement of circuit areas.

The invention of claim 1 is a pixel light-emitting region and circuit region arrangement method for arranging light-emitting regions (23) and circuit regions (24) of display pixels arranged in stripes.
The light emitting area (23) and the circuit area (24) of the adjacent pixels on the left and right are mirror-reflected by 180 degrees, and the light emitting area (23) and the circuit area (24) of the pixels of the entire display are interlaced. This is a method for arranging the light emitting region and the circuit region of the pixel.
The invention of claim 2 is the method of arranging the light emitting region and the circuit region of the pixel according to claim 1, wherein the pixels in the same column are shifted in the vertical direction, and the scanning line (22) passing through the circuit region (24) after adjustment. Is adjusted, and the layout of the scanning line (22) has a linear shape.

  According to the present invention, the black dividing line of the image is erased by adopting the layout method of the stripe arrangement, so that a good image display effect can be obtained, and a good character display capability can be maintained.

  The present invention is also convenient for layout as a collinear line on a scanning line by adjusting the arrangement of circuit areas.

  In order to solve the black line problem of a display image in which a circuit area is generated in a known technique, in the present invention, a circuit area and a light-emitting area of an active display in which pixels are arranged in a stripe form have a specular reflection form of 180 degrees, and adjacent pixels Arrange the circuit area and the light emitting area in the middle so that the original linear array system with order is complemented by adjacent pixels, and the display area is divided by the black line without arranging the circuit area on the same straight line of the same column To solve the problem.

  FIG. 6 is an array display diagram of the light emitting region (23) and the circuit region (24) of the pixel of the present invention. In the present invention, the distribution of the entire color is made uniform by arranging the circuit position and the light emitting position inside the pixel, thereby distributing the same non-light emitting area (circuit area (24)) by distributing the same easily detected characteristic. In a disperse display, that is, in a striped arrangement, the light emitting area (23) and the circuit area (24) of pixels adjacent to the left and right are mirror-reflected by 180 degrees, and the light emitting area (23) and the circuit area (24) are arranged. Form a spaced-apart array in which they uniformly cross. That is, the phase difference between the G pixel adjacent to the R pixel is set to 180 degrees, the phase difference between the B pixel adjacent to the G pixel is also set to 180 degrees, and the others are assumed to be analogized. A black line region at the time of display on a known stripe array display is cut by a light emitting region (23) of a neighboring pixel, thereby forming a mixture of a light emitting region (23) and a non-light emitting region (circuit region (24)). Thus, the displayed screen is made uniform, and the division effect caused by the black lines formed by the circuit region (24) is reduced. Further, when the area of the transistor or capacitor in the circuit region (24) increases, the light emitting region (23) and the circuit region (24) are arranged in a relative proportion of 50:50 and 33:67, as shown in FIGS. It is as follows.

  FIG. 9 shows an arrangement and layout example of the light emitting region (23) and the circuit region (24) of the pixel of the present invention. In the present invention, the left and right adjacent pixels have a 180-degree specular reflection array, and a light-emitting region (23) and a circuit region (24) are uniformly mixed to form a display effect. At this time, the phase difference between the G pixel adjacent to the R pixel is 180 degrees, the phase difference between the G pixel and the B pixel adjacent to the G pixel is 180 degrees, and the data line (21) and the scanning line (22) ) Is laid out along the circuit region (24). A red R pixel is arranged in the first column C1 on the left side, and a green G pixel is arranged in the second column C2 adjacent thereto, and the positions of the light emitting region (23) and the circuit region (24) of the adjacent pixels in the two columns. The phase difference is 180 degrees, that is, using a specular reflection of 180 degrees, a set of complementary pixels (the light emission area (23) and the circuit area (24) of the odd-numbered column pixels are fixed and the light emission of the even-numbered column pixels is fixed). Region (23) and circuit region (24) are rotated 180 degrees), and C2, C4, C6, C8. . If the light emitting area (23) and the circuit area (24) of the CM column pixel are rotated 180 degrees and newly combined and arranged, and then filled in order, the display array of uniform R, G, B pixels as a whole is arranged. Is obtained. We notice that the light emitting region (23) and circuit region (24) of the same row (R1, R2... RN) intersect and are separated from each other.

  Further, the present invention further shifts the vertical direction (data line direction) of pixels in the same column, of which the shift distance is the vertical distance of the circuit region (24), and the scanning line (22) passing through the circuit region (24). ) And the original crank shape shown in FIG. 9 can be corrected to a linear shape as shown in FIG. This is convenient for layout, reduces errors at the time of mask checking, prevents shape control of process conditions and incomplete control of shape etching, and arranges scanning lines (22) and data lines (21) vertically and horizontally. And removing defective factors in the process.

  Currently, for mobile phones, PDAs or other portable electronic display products, a large number of image display functions are rapidly growing in such products, and the information received by the user is more inevitable than the image format information is text information. Too many. The stripe arrangement of the light emitting region (23) and the circuit region (24) of the present invention exhibits a mirror reflection of 180 degrees and intersects, that is, the wire fence divides the frame by the arrangement of the light emitting region (23) and the circuit region (24). This eliminates the need to shift the position of the well-known delta array pixels to the left and right, makes the display image uniform, and also has a good character display effect.
