Description
Technical field
The present invention is relevant for a kind of layout method of image, and particularly relevant for a kind of layout method that improves image quality.
Background technology
The human dynamic image that can see the earliest is the film of documentary film form.Afterwards, the invention of cathode-ray tube (CRT) (Cathode Ray Tube is called for short CRT) successfully derives business-like televisor, and becomes the electrical home appliances of each family's indispensability.Along with development of science and technology, the application of CRT expands to the desktop monitor in the computer industry again, and makes CRT scene many decades nearly.But the made all types of displays of CRT all face the problem of radiant rays, and because the structure of internal electron rifle, and make that display is bulky and take up space, so be unfavorable for thin type and lightweight.
Since above-mentioned problem, and make the researchist start to develop so-called flat-panel screens (FlatPanel Display).This field comprises LCD (Liquid Crystal Display, abbreviation LCD), Field Emission Display (Field Emission Display, abbreviation FED), Organic Light Emitting Diode (Organic Light Emitting Diode, be called for short OLED) and plasma display plate (Plasma Display Panel is called for short PDP).Wherein with LCD the most eye-catching and have slimming, lightweight and little, in the characteristic that maximizes etc., and meet the modern times and following new from generation to generation portable radio communication and the technology of network.
For the image quality that LCD presented, the layout method of image is the key factor of decision image quality.Next please refer to Fig. 1, it is the synoptic diagram of the layout of expression LCD.As shown in Figure 1, LCD 10 comprises data line drive circuit 102, scan line drive circuit 104, data line 106 and sweep trace 108, and the point of crossing of each bar data line and each bar sweep trace constitutes a pixel (pixel).And as shown in Figure 1, the special IC on the printed circuit board (PCB) 12 (application specific integrated circuit, be called for short ASIC) 14 is via image incoming line 16, and is connected to data line 106, to drive LCD 10.Moreover the layout method that image incoming line 16 is connected to data line 106 will have influence on the image quality of LCD 10.And when the number of image incoming line 16 increases, the resistance of the wiring of image incoming line 16 and the product of electric capacity (being called for short RC) just become quite important, and badly influence the driving force of special IC 14, and have influence on the power consumption of special IC.On the other hand, when the number of image incoming line 16 increased, it is extremely important that the load difference that the image incoming line is 16 also can become, and cause the situation of image inequality.
Next please refer to Fig. 2, it is the schematic layout pattern of the known a kind of image of expression.In Fig. 2, the image incoming line is the n bar altogether, and LCD comprises pixel 202, control circuit 204 and the n bar data line of single section.As shown in Figure 2, data line is to be connected with the image incoming line in the mode of in-line arrangement, that is the 1st data line be connected to the 1st image incoming line, and the 2nd data line is connected to the 2nd image incoming line, and n bar data line is connected to n bar image incoming line.Be noted that in addition, in Fig. 2, data line also can be connected with the image incoming line against the mode of arranging, that is the 1st data line is connected to n bar image incoming line, article 2, data line is connected to n-1 bar image incoming line, and n bar data line is connected to the 1st image incoming line.Moreover, by Fig. 2 also as can be known, article 1, the number of times of the line juxtaposition of image incoming line (cross overlap) is 0 time, article 2, the number of times of the line juxtaposition of image incoming line is 1 time, article 3, the number of times of the line juxtaposition of image incoming line is 2 times, the rest may be inferred, and the number of times of the line juxtaposition of n bar image incoming line is that (n-1) is inferior.For the line juxtaposition, each line juxtaposition produces an overlap capacitance.And if the overlap capacitance of image incoming line is bigger, then special IC will more be difficult to drive.With this known layout method, because the line juxtaposition number of times difference of every image incoming line, the load that will cause each bar image incoming line is different with overlap capacitance, and thus, special IC just needs drive each bar image incoming line with different driving forces.
And the schematic layout pattern of known another kind of image please refer to Fig. 3 and illustrates.In Fig. 3, the image incoming line is the n bar altogether, and LCD comprises a plurality of pixels and a plurality of control circuit, and these pixels and these control circuits are distinguished into the individual section 304 of the 1st section 302 to m (m is a positive number).Wherein, the 1st section 302 comprises the 1st section pixel the 306, the 1st control circuit 308 and n (n is a positive number) bar data line 310.Similarly, m section 304 comprises m section pixel 312, m control circuit 314 and n bar data line 316.With 1/4th common intermediate forms (quarter commonintermediate format, be called for short QCIF), if the image incoming line is the n bar, the number m=176 * 3/n of section then.
As shown in Figure 3, data line in each section is to be connected with the image incoming line in contrary row's mode, that is n bar data line is connected to the 1st image incoming line, and n-1 bar data line is connected to the 2nd image incoming line, and the 1st data line is connected to n bar image incoming line.Be noted that in addition, in Fig. 3, data line in each section also can in-line arrangement mode and be connected with the image incoming line, that is the 1st data line is connected to the 1st image incoming line, article 2, data line is connected to the 2nd image incoming line, and n bar data line is connected to n bar image incoming line.Moreover, by Fig. 3 also as can be known, article 1, the number of times of the line juxtaposition of image incoming line is 0 time, article 2, the number of times of the line juxtaposition of image incoming line is 1 * m time, article 3, the number of times of the line juxtaposition of image incoming line is 2 * m time, the rest may be inferred, and the number of times of the line juxtaposition of n bar image incoming line is (n-1) * m time.With this known layout method, because the line juxtaposition number of times difference of every image incoming line, the load that will cause each bar image incoming line is different with overlap capacitance, and thus, special IC just needs drive each bar image incoming line with different driving forces.Moreover, between adjacent front section and back section, the n bar data line of front section is connected to the 1st image incoming line, then the 1st of section the data line is connected to n bar image incoming line, because both line juxtaposition number of times differ too big, the existence of the image that presents making between adjacent sections gapped (gap), and seriously have influence on image quality.
