Description

201227662 VI. Description of the invention: [Technical field to which the invention belongs] Multi-opening::: relates to an electric enthalpy compensation method, in particular to the picture of the winter φ two yang 汲 关于 关于 扫描Voltage compensation method. [Prior Art] The light source is not; the first liquid crystal display itself does not emit light by itself, so it must be illuminated by means of illumination. For example, hand

ΙΓΓ11 makes the cutting of the cut order (4); the electric meter used in the car electric meter or the "machine" is clearly displayed by the rear illumination source. These thin white light sources on the back are called moonlight. Back Light). The general liquid crystal display uses a color filter to pass through the light source, so that a single pixel simultaneously displays the components of the three primary colors, and displays an undesired color. In such a liquid crystal display with a color filter, The parental element is composed of three sub-pixels (sub_pixei), which respectively correspond to the color filter, the red, green and blue filters of the light film, while the human eye receives the light and passes through the color light film. The displayed red, green and blue light can be combined to 'receive the color of the pixel. However, the # color filter will affect the overall light transmittance of the liquid crystal display, in addition, the 'color color film It also affects the size of the display point (d〇t) of a single element of the liquid crystal display, which causes the resolution of the liquid crystal display to be limited by the color filter. In order to improve the above resolution and light transmittance, etc. development of A color Sequential liquid crystal display. The color sequential liquid crystal display can sequentially display three primary color components of one pixel to present an excellent shirt. Each of the pixels of the color sequential liquid crystal display is provided by three The light source, 201227662 emits red, green and blue light respectively as backlights. In the frame time, the pixels can respectively turn on red, green and blue according to the display data. The visual persistence of 2 eyes can be recognized by people. Therefore, the color sequential liquid crystal display does not need to be provided with a color light-emitting sheet, and the size of the color pixel is smaller than that of the liquid crystal display with a color light film; high resolution. It can not reduce the cost, and can be improved: the pixel of the liquid crystal display is based on its control signal and data signal, and the crystal display of the seat is displayed. In addition, the color sequence liquid must be composed of three primary colors. Light source, respectively in the same -

The frame emits red, green and apricot J. 4 first as a backlight to display a color image. The mother scans the signal at each ', image-color backlight, so the color sequence liquid = display _The scanning speed (or frequency) of each day must be scanned. The scanning speed (or frequency) of the daily display is increased to 3 times that of the conventional LCD. Half) Solving the high-frequency problem required for color-sequential liquid crystal display, - the panel structure of the multi-sweep line is opened and the seed line is opened at the same time and _, σ system will scan the celestial layer, and then trace the 4 Switch the open frame S==r on multiple scan lines. Specifically, the switching time of the three scan lines of the scan line is the same as that of the conventional architecture, and the on/off-bar::=: and the conventional liquid crystal display-the third-line three-open architecture is thus known. The amount of the prime is the traditional three of the traditional architecture; one of the following:: This is the second 4 201227662 architecture 3 times. Therefore, the scanning frequency of the display binary s of the display with the scanning line is increased, thereby improving the color-sequence liquid crystal problem, and if it is used for the color-opening wood structure, the phenomenon of uneven coupling of the pixel capacitance is likely to occur, if used In the night crystal display, it is easy to produce an obvious color checkerboard problem. And the body" = crystal display, it is easy to cause the open frame of the flashing of the face, from the figure in the figure ▲ 勹 勹 ... 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 田 tl tl tl tl tl tl tl tl ^4 will simultaneously turn on 'At the same time turn off at t2, sweep: off the second instant _' and because the scan line (4) 3, and G4 from the open '曰' in the case of electricity and conservation, the charge on the element of the halogen is no longer Into the shell line' will cause the capacitance surface effect, this effect will be reflected in the stray capacitance Cpg between the halogen and the scan line, which will affect the book's display: electric house, as can be seen from Figure j, Since the scan line (7) value is off:, the electric valley Cpgl will have no capacitive coupling effect, and the scan line Q will turn from on to off, so Cpg2 will produce a capacitive surface effect, so the display money vdispI will be affected by The capacitance of the scanning line G2 is affected by 2, and similarly, the second display electric dust Vdlsp2 is subjected to the capacitance Cpg2 coupled to the scanning line G2, and the capacitance coupled to the scanning line (7) and the third display electric dust Vdisp3. Capacitor Cpg3' that is lightly coupled to scan line G3 and capacitor Cpg4 coupled to scan line G4 influences. As can be seen from the above, the first display voltage Vd1Spl is only affected by one stray capacitance, and the second display voltage Vdisp2 and the third display voltage Vdisp3 are affected by two stray capacitances, and & Vdispl is affected by the capacitance consuming effect. Turn 5 201227662 small, which leads to the inconsistency of the asymmetry of the voltage display of the three halogens, which makes the adjustment of the common electrode electric waste 'the common electrode voltage can not converge ^ and thus cause the color checkerboard phenomenon in the color sequential display. Generally, the liquid crystal display causes the flickering of the face. The degree of asymmetry of the display voltage of the halogen is inconsistent due to the difference in the amount of capacitive coupling. If the point conversion with the color field and the adjustment method of the common electrode voltage 'will result in the display of the gray surface that should be displayed as a color checkerboard, for example, the three commonly illustrated aspects are shown in the first figure of FIG. 2, respectively. The state, the second state, and the third aspect, wherein the first display voltage Vdispl is symmetrical when the common electrode voltage is adjusted to the first state, and the normal gray scale is displayed, but the second display voltage Vdisp2 And the third display voltage

Vdisp3 is still not symmetrical, and cannot display the normal gray scale; if the common electrode voltage is adjusted to the second state, the second display voltage Vdisp2 and the third display voltage Vdisp3 can be made symmetric, but the first display voltage is caused.

Vdispl cannot be symmetrical and cannot display normal gray levels. Therefore, the first aspect of the Thai and the second aspect of the facet will produce a color checkerboard phenomenon due to the asymmetry of the display voltage of some of the elements, thereby causing the horizontal stripe of the picture, so in order to make the color checkerboard phenomenon The horizontal stripe is not so obvious, and the co-electrode voltage adjustment method of the second aspect of the compromise is selected, but the color checkerboard phenomenon still exists. In the conventional scan line multi-open architecture, there are still some difficulties and shortcomings to be overcome.

Therefore, the second pixel to be solved is also gray-scale. By the above method, the t-gray value of the present element The positive polarity and the negative polarity, respectively: fixed;; after the fairy gray value, to establish a pixel voltage compensation table, then, by

The pixel voltage compensation table outputs the compensated grayscale value to the source^ which is then generated by the source controller-corresponding to the compensated voltage and transmits the =- halogen, so that the first pixel is grayscale and due to other elements Both of them are represented by F-white, so they can eliminate the problem of the color of the checkerboard and the flickering of the screen.

The DDR control is as early as 1 () 6 and then the rearranged image signal is read back ' and passed to the timing control unit 1〇8. The look-up table unit mi has a main component voltage compensation table, which can be used for any data or data to be compensated for: the gray scale value, the original voltage, the voltage to be compensated, and the voltage after the compensation. The purpose of the compensation table is Adjusting the quality of the display voltage error caused by the unevenness of the electric valley, providing the correct display voltage to display the correct gray scale, thereby overcoming the problem of flashing of the face and the color of the checkerboard. Detailed techniques for this pixel voltage compensation table are described in the subsequent sections of this manual. The timing control unit 108 is coupled to the gate controller 11 and the source controller (1), and the basin system is configured to: the source signal and the gate signal are respectively supplied to the source controller (1) and the interpole diode: Specifically, the 'source signal is a mini low voltage differential signal (mim-LVD), and the gate signal package makes the rudder ΓΓΚ ν, μ now 3 start heart (stv) and the base frequency signal source controller 111 Outputting the source signal to the complex system 11110 outputs the closed-circuit signal to the complex scan error to determine the display power of all the pixels in the display panel 112 and the switch 201227662 time, where the 'source signal contains at least one compensation power? It is controlled by the source, and the n is compensated according to the timing control unit (10). The gray scale is used to compensate for the unevenness of the 4 factor capacitors. The grayscale, in turn, eliminates the phenomenon of colored checkerboards and: the face of the butterfly. GammaIclG9 is used to determine the voltage of the pixel grayscale value and transmit the corresponding relationship to the source controller 111. For example, the corresponding grayscale values of the first pixel can be defined in the Gamma IC. Voltage, and the corresponding relationship is transmitted to the source controller (1), and the source/work system 5 111 Å | J can calculate the voltage corresponding to the gray scale value according to the correspondence relationship of the above 30 gray scale values, and This technique is not a feature of the present invention and will not be described in detail herein. Referring to FIG. 4, the present invention discloses a preferred embodiment of the panel pixel voltage compensation method according to the above-mentioned architecture, wherein the panel to which the square is applied is preferably a scanning line multi-opening frame= The scanning line is three open, four open, five open, N open, and so on. Specifically

St: complex pixel group, each element group includes -[pixels and polyphonic A _ 2, for example, if the scan line is a three-open architecture, then the other 昼: right is a known line four open architecture' then there are three The number of other pixels is ^金^: This type of push knows that if the scan line is N-opened, then there are (Ν_υ一^^'' the above-mentioned first---------------------------- In the embodiment, the panel common electrode voltage system::: causes other pixels to display a voltage symmetrical voltage, and even if the voltage is a plurality of gray voltages, for example, the scan line three open frames can make the second and third The pixels show voltage symmetry, as shown in the second 201227662 aspect of Figure 2. In this aspect, the symplectic display -f Γ· ^ The purpose of this example is to make the first

St is also symmetrical, and the steps are as follows: First, in step 2〇1, the book symplectic voltage compensation table pre-established by the look-up unit is used to make 杳矣罝;π.疋儿<旦电 for all grayscale values^(4) What to compensate for - the pixel's value, the original voltage, the compensation ^ and the negative = electricity ^ established by the original grayscale 槿忐 纟, 丨 · + After the voltage is compensated, the gray scale value is not uniform after the compensation. According to the table, the purpose is to adjust the voltage error voltage caused by the capacitor box combination, so that the supplier can be supplied from the source. It correctly displays the problem of the electric panel. In the case of the antrum m 士 / 禅 禅 and the π color chess technique, in the case of e, the positive polarity voltage and the negative polarity of each gray scale value of the first-halogen are obtained in step 2021. However, the table determines that the first book is supplemented by the gray scale value of the compensation element. Specifically, when the first gray scale is to be controlled, for example, the positive electric dust The lower f start grayscale value is 88, then the timing control unit will query the compensated grayscale value corresponding to the pixel compensation 2 original gray I5 white value 8 8 , for example, the gray scale of the 100 gray scale under the positive polarity voltage The order value is 100; then, in step 203, the compensated gray scale value is transmitted to the source binder by using the day-sequence control unit, wherein the compensated gray scale value is queried by the timing control unit. The value obtained by the table is, for example, 1 上述 above. Then 7 in the second step 2〇4 'Using the source control|| will compensate the post-gradation value (4) to the post-compensation pressure, specifically, due to the source controller There is a corresponding value of each gray scale value voltage, so any gray scale value obtained by the receiver can be converted into a voltage. In the source controller, the timing control unit transmits [13 201227662 the compensated gray scale value correspondingly to a voltage value, and the electric compensation voltage. Finally, in step 205, the source controller is used: The compensated voltage obtained in step 204 is output to the first pixel, thereby changing the display voltage of the first pixel, and transmitting and supplying; and generating the incorrect gray scale, thereby suppressing the color checkerboard, The phenomenon of flashing the picture. For the method of establishing the pixel voltage compensation table, reference may be made to FIG. 5, which is an embodiment of the present invention for establishing a pixel voltage compensation table, the steps of which are as follows: First, 'in step 3〇 In the middle, the original gray scale value is set in the middle, and the voltage compensation matrix is used to establish a corresponding compensation voltage for the positive polarity and the negative electric dust of each gray scale value of the first halogen. After the compensation of the gray scale value, the first step of establishing the table is to select an original gray scale value η, taking 8 bits == as an example, η contains the integer of the coffee, and then, the original = gray value is selected. After that, proceed to step 3〇2 to set a second common electrode. The voltage C°m2, so that the other pixels of each pixel group are grayscale, for example, t, if it is a scan line three-open architecture, as shown in the second aspect of Figure 2, the second, the third The halogen display shows the gray scale t-ice grab-white and the second common electrode voltage Veom2 疋 = the common electrode voltage of the panel. Next, in step 303, the first step, the electrode, the Vcom2 is adjusted to The first common electrode voltage Vcoml is such that the first pixel of each-quin group is gray-scaled, for example, if it is a scan line three open frame: the second of the head--the sad picture shows the 'first one element display Gray scale; in step 304, the value of the first common electrode voltage and the second common electrode voltage C is defined as - the absolute value of the difference between the compensation and the positive electric energy, ^ and see FIG. The pixel voltage compensation table of the present invention is shown as an example of an 8-bit 256 gray scale, wherein the compensation voltage 14 201227662 is ΔVOONVcom丨_Vc〇m2|; then, in step 3〇5, the first - the display voltage of the halogen is subtracted from the compensation voltage to obtain the compensated voltage, that is, the display voltage V(4) of the n-pixel in the ηth gray scale minus the above-mentioned lightning: ΔV(n), that is, ν(η)-Λν(η); Finally, in step 鸠f, the compensated voltage corresponds to the corresponding grayscale value, and the complementary step value (4) y(8) is obtained. After the compensated grayscale value is stored, = Medium, for other grayscale values (for example, the lower-gray value state is the second step of 302. By the above method, the compensated voltage corresponding to the :: - gray scale value and the compensated gray scale value can be obtained, for example. The fire wide value η - 88 ' can be obtained by the operation of this table to obtain the compensation value gray (88) = l 〇〇. The white value of the above examples are all for the compensation of the complex element group, for example, the scan line three open architecture! In addition, in the embodiment, it is also possible to compensate for the complex voltage = two: the voltage of the input voltage, for example, the second, third or second, or seven or eight elements of the scanning line three-open structure.
