Description

201040917 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to an image display. [Prior Art] An image display typically has a matrix of pixels including a plurality of pixels arranged in a matrix, and a plurality of scan lines for transmitting scan signals to scan the pixels. In addition, the image display usually has a scan driver, a source driver, and a plurality of data lines that couple the source driver to the pixels. The scan driver is responsible for generating the above scan signals. The source driver is responsible for converting the display data into potential values, which are passed to the pixels being scanned to set the potential of the pixel electrodes. Taking a liquid crystal screen as an example, the liquid crystal material corresponding to each pixel will rotate with the potential of the pixel electrode to display various brightnesses. However, there is a parasitic capacitance between each pixel and its upper and lower scan lines; the scan signal variation (rising, falling, falling edge, ❹ or falling edge) on the scan line is easily reflected by the parasitic capacitance at the potential of the pixel electrode. Causes the brightness of the pixel to shift. The above phenomenon is called a feedthrough effect. The piercing effect can seriously affect the quality of the image display, which is an urgent problem to be solved in the technical field. SUMMARY OF THE INVENTION The present invention discloses an image display device in which a pixel matrix structure is disclosed, which can effectively solve the influence of the feedthrough effect on a half source driver (HSD) panel, a 2G1D panel, and the like. AU0903199/0632-A51576-TW 3 201040917 This paragraph describes the knot=number of the pixel matrix disclosed by the present invention, =: a plurality of first color pixels, a complex number = |- scan line is responsible for transmitting a first scan signal to scan the first :: 1 color 7-cell second scan line is responsible for transmission - second scan signal scanning, etc. In addition, an embodiment of the image display of the present invention is more capable of - for - color data conversion, and for the above = - Second color data (4) Conversion. The source driver material is converted into a voltage value for writing a human scanning color = a first color gamma value is used (one va two = two color data - the ink conversion is -$ two color gamma value. The value of ± is different from the value of the second color gamma. In another embodiment of the color gamma image display, the first-one aperture ratio is different from the second aperture ratio. The above and other objects, features, and advantages of the invention will be more clearly described below. The seasons <study embodiment' and the accompanying drawings are described in detail.

AU0903199/0632-A5I576-TW 1 Shishen 1SCM 201040917 linejScan, and a scan line Scan2. Scan lines Scan! and Scan are each responsible for passing a scan signal to scan the pixels controlled by each. As shown, scanning of all red pixels R in column 102 is performed by scan line Scan!, scanning of all green pixels G in column 102 is performed by scan line Scan2, and scanning of blue pixel B on column 102 is performed. Part of it is responsible for the scan line Scan! and partly by the scan line Scan2. The same structural rules are also applied to the other columns 104, 106, 108 of the pixel matrix 100. In summary, the structure rule is such that each column of the pixel matrix has at least two color pixels and two scan lines, wherein the scanning of the first color pixel is unified by the first scanning line, and the scanning of the second color pixel is unified by the first The second scan line is responsible. In the example where there is a third color pixel, the third color pixel of each column may be partially scanned by the first scan line of the column and partially scanned by the second scan line of the column. Corresponding to the pixel matrix 100, the first color, the second color, and the third color pixel may be red (R), green (G), and blue (B) pixels, respectively. The above structural rules are beneficial to improve the influence of the feedthrough effect on the kneading surface. This paragraph is illustrated by a column 102. Since the red pixel R is scanned by the scan line Scan!, the scan line Scan and Scan2 have the same feedthrough effect for the red pixels R. After reaching the set potential, the pixel electrode of the red pixel R will be affected by the signal variation of the scan lines Scan! and Scan2; the influencing factors include: the falling edge of the scanning line Scan!, or the rising edge of the scanning line Scan2 , falling variation, falling edge. Similarly, since the green pixels G are scanned by the scan line Scan2, the green pixels G have an approximate feedthrough effect. After the pixel electrode of the green pixel G reaches the preset potential, it is affected by the falling edge of the scanning line Scan2. Compared to the red image AU0903199/0632-A51576-TW 5 201040917, the green pixel G is slightly less affected by the feedthrough effect. Since all the red pixels R are nearly uniform in the feedthrough effect, the feedthrough effects of all the green pixels G are nearly identical, and the feedthrough effect of the red pixel R is much more serious than the green pixel G. Therefore, the present invention further proposes A technique in which a red data-voltage conversion is designed for a red pixel R in a source driver of an image display, and a green data and voltage conversion is designed for a green pixel, wherein a red data-voltage conversion considers a more serious feedthrough effect. And the green data-voltage conversion considers a slight tunneling effect. The present invention further proposes an embodiment in which the feedthrough effect is compensated by the gamma value of the general data-voltage conversion. In general, the higher the gamma value, the higher the relative potential after conversion. In this embodiment, the red data-voltage conversion adopts a red gamma value, the green data-voltage conversion adopts a green gamma value, and the red gamma value is higher than the green gamma value, so that the feedthrough effect is more serious. Red pixels get more compensation. Furthermore, since the human eye is less sensitive to blue, the blue pixel B feedthrough effect in the pixel matrix 100 may not be considered. Considering the feedthrough effect of the blue pixel B, a blue data-voltage conversion can also be designed for the blue pixel B in the source driver. Compared to the red and green data-voltage conversion, the blue data-voltage conversion can be less stringent for the feedthrough effect. Figure 2 illustrates the above technique. Image display 200 includes a pixel matrix 202, a scan driver 204, and a source driver 206. Pixel matrix 202 follows the structural rules disclosed herein. Scan driver 204 is responsible for providing all of the scan line scan signals within pixel matrix 202 to sequentially scan pixel matrix 202. The source driver 206 AU0903199/0632-A51576-TW 6 201040917 shows the use of the control unit (not shown in the figure). For the pixel color pixels in the scan in the first matrix 202, the source driver 206 provides a first color-electricity-house conversion 208; and for the second two-color data voltage conversion 21 . In addition, the lightning=driver 206 is more for the third color pixel: - the first - the power ϋ ηη. The first color, the second color, and the third color data are converted 208, 210, and 212 to compensate for the feedthrough effect of the first and second color pixels, respectively. By the second = two = medium, for example, the compensation feedthrough effect) can also be made as a red pixel R: for example, a specific aperture ratio is used to make a green pixel G at a specific aperture ratio, and the aperture ratio of the Γί ί ί is lower than that of the red pixel R Opening ratio. Since the feedthrough effect of ^ is more serious, the transmission aperture ratio is larger (and the green i design can achieve the compensation effect, which makes it consistent with the green pixel G transparency to reduce the difference in display.

❹The distance between the pixel and the scan line of each other= can reduce the three-sigma electric valley effect, but will sacrifice the aperture ratio of the pixel; if arranged by the present embodiment, the red pixel R and the green pixel G Ϊ = Ϊ = via consistency and can compensate for 'only need to consider the blue pixel's feedthrough. Since the human eye is less sensitive to blue, the distance between the element and the scanning material is improved, and the distance I must be too large (as long as the difference in brightness of the blue is acceptable to the human eye), so it is not necessary Sacrifice too much aperture ratio to achieve this design. Go back to the first! The embodiment shown in the figure shows that it has a special design for the data line. As shown, the data lines are arranged one to one on the pixel matrix 1 , for

The data line 114 is coupled to a single column (column 1, 2, 106) of a row 126 and coupled to a double column (columns 104 and 108) of a row 128. In addition, the other pair of data lines 116 and 118 are also electrically connected together, and the signal transmitted together is d3. The data line 116 is coupled to a single column (column 1, 2, 106) of a row 124 and is converted to a double column (columns 1〇4 and 1〇8) of a row 126. The data line 118 is coupled to a single column (column 102, 106) of a row 128 and coupled to a sequence of 13 双 double column (column 104 and 1 〇 8) pixels. In a frame, DJD3 passes the electricity of the opposite polarity. The data line shown in Figure 配置 is configured to form a column inversion panel. The data transmitted by each of the above pairs of data lines has a polarity (maintaining + polarity or maintaining _ polarity) in a one-sided period. This facilitates a pre-charge technique to implement a scan line driver for each column of Scani and Scans. The upper scan signals partially overlap.

In addition, the embodiment shown in Figure 3 has a special design for the data line. As shown in the figure, the data lines are arranged in a pair on the pixel matrix 3A. Taking a pair of data lines 312 and 314 as an example, the two are electrically connected together, and the signal transmitted together is d2.
