Description of the invention (1) The present invention is about the method of moving the liquid crystal display device. Usually, when driving a simple matrix type liquid crystal display device, an electric averaging method is used. However, the actual liquid crystal panel is composed of scanning and multiplying electrodes whose resistance is not equal to 0, and the liquid crystal layer generates a medium. Therefore, when the conventional voltage averaging method is used for driving, the effective voltage applied to the display point formed by the crossing of the scanning electrode and the signal electrode changes according to the characters displayed on the liquid crystal panel and the garden shape of the garden. As a result, the display is uneven. The problem of seeding is the problem of conventional knowledge. The countermeasures include, for example, Japanese Patent No. 62-31825, No. 6-0-1 9 1 95, and No. 60-19196, which are shown between 1 frame and multiple inversions are applied to the LCD panel. The method of voltage polarity (hereinafter referred to as line inversion driving method). In addition, there is a method for correcting the display unevenness of No. 63-159914, which is a patent application filed by the inventor of the present invention. However, the above-mentioned line inversion driving method only improves the display unevenness caused by changes in the frequency characteristics of the liquid crystal held by the liquid crystal panel due to the application of mildew®. It is slightly effective and cannot completely eliminate the display {please read ttThe precautions on the face and then fill in this page) Please let me know if you want to wait. If the sentence is clear, the original name of the Bodhisattva is not yet issued, but the method of the Buddha's law is correct. After the law is repaired, if there is no display, if there is evenness, it will not show the goodness. The reformation of the Bodhisattva may be obtained. Even though it is not uniform-the Central Plains Bureau of the Ministry of Economic Affairs should print it. If the capacity is not changed, it will still be displayed and corrected. 1 The flute surface of the pressure plate will be clearly expressed with crystal liquid. 4 4 11 11 β β According to the photos, the uniformity should be displayed first and then not displayed to show 4 (210X 297) ) 201825 A6 B6 V. Description of the invention (2) The liquid crystal panel 1 holds the liquid crystal (not shown) with a pair of substrates H2, 3, forming a plurality of lateral scanning electrodes Y1 ~ Y6 on the substrate 2 on the substrate 3 A plurality of double-numbered electrodes XI ~ Q6 are formed in the longitudinal direction. The positions where the scan electrodes Y1 ~ Y6 and the multiplex poles XI ~ X6 cross respectively become display points. The LCD panel 1 has 6x6 display points. The reason is that there are usually more points for the convenience of explanation. The oblique line in the figure indicates the lighted part (hereinafter, the sticky display point is called the lighted point, and the unlit display point is called the unlighted point), and the middle part shows the temporal content of the chessboard_case. To the left of its scanning pole, the display unevenness improvement method shown in the application No. 63-159 9M applied by the inventor of the present invention is applied. Scanning Frost® waveforms that vary in type. In other words, when changing from selecting one scan electrode to selecting another scan electrode, according to the difference between the number of lighted points on a certain scan electrode and the number of lighted points on the selected scan electrode, the non-selected voltage Heavy weight correction of pressure. However, since the display content shown in the figure is always zero, the correction voltage is not applied to the non-selected voltage. On the double pole, an alternating voltage wave is applied from above to below. At this time, the liquid crystal panel 1 becomes black when the effective voltage applied to the display point increases, and the temporal display of the jade piece is performed. When displaying the display pattern in this circle, the temporal display points formed by the horns XI, X3, X5 of the times, the more the display points above the lighter, the darker the points below. On the contrary, the double number "Pole X2, X4, X6 is formed by the display (please read the notes on the back of KI before filling in this page) • JTT ... line.

In other words, the closer to the display stick on the side of the applied voltage waveform, the smaller the effective voltage actually applied. The inventor of the present invention has found the following facts after many experiments and studies on the display unevenness. This fact will be explained below with reference to Figure 15 U) ~ (c). Figures 15 (a) to (c) show the waveforms of the liquid crystal panel 1 of Figure 14. In the fifteenth circle (a), the solid pressure line shows the pressure waveform on the number electrode X3 at the position of the display point D31 in FIG. 14. The voltage waveform on the double-number electrode X2 showing the position of the point D21 is indicated by a dotted line. In the figure, for the convenience of explanation, the solid waveform and the dotted waveform are staggered from each other, but in fact they are the same. Fifteenth- (b) shows the voltage waveform on the double-numbered electrode XI at the positions of the display points D21 to D31 of the 14th group. 15th circle-(c) shows the difference between the voltage waveform on the scan electrode Y1 at the position of the display point D31 on the 14th circle and the voltage waveform on the multiplier electrode X3. In other words, the solid line indicates the waveform of the pressure applied to the display point D31. Similarly, the dotted line in Fig. 15 (c) shows the pressure waveform applied to the display point D21. The slanted line indicates the difference between the flute K applied to the lit point and the unlit point, rather than producing an uneven electric K difference. In _, 70 ^ 1 ^ 2 ^ 3 ^ 4 ^ 5 represents the voltage. Suppose Xiaoyi V5, V3, V0, V4 is the first group of lights, unlit, select non-S selective pressure, flute pressure V0, V2, V5, V1 is the second group of lights, unlit Select, non-selective pressure, apply the selected, non-selective pressure to the scanning pole, and light, unlit pressure to the signal dipole. (In the future, the waveform of the pressure applied to the scanning pole will be referred to as the scanning pressure waveform, and it will be applied to the number one 5-{please read the precautions on the back before filling this page) • ^, .Order. • Paint. · f 4 (210X 297 /: ^) 201825 A6 B6 Printed by the Central Standards Bureau of the Drip Department ^ V. Description of the invention (4) The waveform of the electrode is called the double-numbered voltage waveform). The 1st and 2nd Yuan pressure group encounters a periodical change. In this example, the selection voltage is applied to all the scan electrodes Y1 to Y6 and then converted (this period is called one frame, which is indicated by the following 1 and 2 in the figure). In Fig. 15 (a), the moment between the stick D31 and the end of the applied double voltage waveform is shorter, so the signal on the stick D31 has almost no voltage waveform reduction on the X3, and the applied signal voltage The waveform is completely applied on it. However, as shown in FIG. 15-(b), because the distance between the point D21 and the end of the applied signal voltage waveform is long, the applied voltage waveform on the signal electrode X2 at the point D21 occurs significant reduction or distortion. Signal voltage waveform. In other words, the integrated circuit formed by the electric bladder of the double-numbered electrodes XI ~ X6 and the capacitance of the liquid crystal as the medium causes the voltage waveform to be reduced and distorted. Therefore, when the lighting electric S (unlit frost voltage) applied to the signal electrodes XI, X3, X5 is converted into unlit (lighting voltage), the nail-shaped noise generated on the scan electrode Y1 is larger than the double-number electrode Noise when X2, X4, X6 lighting voltage (non-lighting voltage) is converted into non-stick bright voltage (lighting voltage). Therefore, the lighting voltage of the signal electrodes XI, X3, X5 (unlighted voltage) is converted into an unlighted voltage (lighting ®) and the nail-shaped noise generated at the scan® pole Y1 will become a controlling factor. Therefore, as shown by the solid-line waveform in FIG. 15 (c), the effective voltage applied to the display point D31 decreases, and as shown by the dotted-line waveform, the effective voltage applied to the display point D21 increases. At this time, the noise generated on the 14th scan electrode Y6, on the contrary, the noise generated by the X2, X4, X6 in the multiplier becomes the controlling factor, (please read the notes on the back first Qiong then fill out this page). 蛑.-打 _ • 姝.

Description of the invention (7) In terms of extinction, from selecting the scanning electrode Yn to selecting When the trace electrode Yn + 1, a spike noise is generated on the trace electrode Yk of the K-th prong electrode, and the absolute value of the value of the coordination function I (k) is generated. In other words, when the value of the function I (k) increases, large noise is generated. The direction of noise generation is determined by the sign of the function I (k). In other words, when the voltage direction of the nail-shaped noise matching the value of the function I (k) on the scan electrode Yk and the change in the voltage waveform applied to each signal electrode become the same phase, it is applied to the signal electrode and the trace electrode Yk The effective voltage of the formed display points decreases and the display becomes lighter. When the phase is opposite, it increases and becomes thicker. Due to the above structure, the phenomenon of display unevenness remains. In the following, referring to Figure 16 and Figure 17, the difference in display unevenness that still exists after implementing the pressure correction method will be described. Picture 16 and circle 17 show the liquid crystal panel 1 and the different display contents. In the circle, the structure of the liquid crystal panel 1 is the same as that of the liquid crystal panel 1 in the 14th circle. Therefore, the description is omitted based on the same representation. In Figure 16, in Figure 17, the left of Y1 ~ Y6 is drawn down. In the method for improving the display unevenness of the application No. 63-15994 filed by the inventor of the present invention, the method for correcting the pressure of the display unevenness by changing the horizontal pull to the display unevenness is to apply the scanning pressure waveform that changes due to the display circular shape. . In other words, in accordance with the number of lighted points Z on the selected tracing pole, overlap the "pressure" on the Mselect® pressure. The display contents in the 16th and 17th mean that the similar quadrilaterals are displayed at the position moved to the left and right ends respectively (please read the precautions on the back before filling out this page). 装 _. 定 ·. 线.

Description of the invention (8) Same The corrected pressure is applied to each of the scan electrodes Y1 to Y6 of the liquid crystal panel 1 of the 16th and 17th liquid crystals. According to the 16th circle, the correction K is too much, so that the display of the four healthy angles in the horizontal direction produces thicker display unevenness. On the contrary, according to the 17th circle, the correction voltage is low, and the display unevenness caused by the residual lateral pull-out line, in other words, the lighter display unevenness in the horizontal direction of the four inclination angles of the display will remain entangled, The reason is that the resistance of each of the scanning electrodes Y1 to Y6 constituting the liquid crystal panel 1 and the capacitor formed by the display point cannot constitute an integrating circuit, and the capacity of the capacitor formed by the lighting point is greater than that of the capacitor formed by the unlit point capacity. In other words, the effect of distorting the waveform from the end of the applied flute pressure waveform (hereinafter referred to as the drive order) from the brighter lighting point is greater than that from the closer lighting point. Therefore, if the lighting sticks at a faster speed, there will be greater distortion. Therefore, if the bright point is away from the driving end of each scan electrode Y1 ~ Y6, the waveform will be distorted if the correction is included.

Description of the invention (11) That's it. The following describes a specific embodiment of a liquid crystal display device that performs seed correction. The first circle shows the structure of this embodiment. In the garden, 101 is a liquid crystal cell, which is generally composed of a liquid crystal panel 201, a scan electrode driving circuit 205, and a signal electrode driving circuit 213. 102 is a series of control signals used to control the operation of the liquid crystal display device, including the latch multiplier LP, the frame signal FR, the data rotation multiplier DIN, the X drive shift clock signal XSCL and others. 103 is the data multiple, which is commonly used to determine the multiple of the display pattern. The data signal 103 changes when the signal XSCL rises, and is input to the liquid crystal cell 101 and the voltage waveform correction circuit 104 when it falls. 104 is a voltage waveform correction circuit (hereinafter referred to as a correction circuit). 105 is the power supply circuit. 108 is a circuit that generates a clock signal 110 synchronized with the multiple LP. 106 is two sets of power supply (hereinafter referred to as Y power supply) needed to drive the scanning electrode output from the power supply circuit 105. 107 is the two sets of power supply (hereinafter referred to as X power supply) required to drive the No. 1 pole output from the Enyuan 105. 109 is a correction multiple used to determine the amount of correction voltage that the correction circuit 104 rotates. 110 is a multiple of the signal LP synchronized with the frequency division Xiaolu 108 (hereinafter referred to as the correction clock). An example of the specific structure of each component in the first circle is described below. FIG. 2 shows an example of the structure of the liquid crystal cell 101. In the circle, 201 is a liquid crystal panel, on which a pair of substrates 202, 203 holding a pair of liquid crystal layers is formed on a substrate H202 with horizontally arranged scan electrodes Y1 ~ Y6, and a vertical arrangement is formed on the S-substrate 203 The number of times is XI ~ X6. The double electrodes XI, X3, X5 have on the upper side a wave size that accepts double pressure-13- A 4 (210X 297 public) (please read the precautions on the back before filling in this page). 蛑., Order · 201825 A6 B6 5. Terminals of the invention description (12), and X2, X4, X6 have terminals under it. The display points Y1 ~ Y6 and the double electrodes X〗 ~ X6 cross to form a display point 204. In this example, for convenience of explanation, the structure of the liquid crystal panel 201 is 6x6 dots. However, the present invention is not limited thereto. 205 is a scanning drive circuit (hereinafter referred to as Y drive Cui), which includes a shift register 206, a shift register 207 that is composed of a plurality of bits, and a latch circuit 208 The counter 209 is composed of a detection circuit 210, a conversion circuit 211 and a level shifter 212. The output of the level shift circuit 212 is introduced into the liquid crystal panel 210 and the scanning electrodes Y1 to Y6. The third plaque shows a more specific example of the Y driver 205. In the circle, 206 is a shift register. When the signal LP falls, the signal DIH is input, and when the signal LP falls, the multiple number DIN is sequentially transmitted to each register of the shift register 206. The multiplier DIH takes the high potential "Η" as the active "1". Generally, it is one at a time at intervals of the number of scans Y1 ~ Y6 or the number of more multipliers LP. Therefore, the data of " 1 " passes into the shift register 206, and the other becomes non-active "〇". At this time, each register rounds off its contents as the control signal C0. 207 is a shift register composed of registers with multiple Burmese bits. In this example, Wu consists of 5 bits to form a child register. The shift register is operated by the action of the Y-corrected shift clock (hereinafter referred to as YCSCL) which constitutes correction number 109. Due to the function of the multiplier YCSCL, the strong multiples (in this case, 4 bits, 10 to 13) used to determine the amount of correction that constitutes the correction multiples 109 are entered in sequence and the sign used to determine the correction of the (K1 first read the notes on the noodles before filling out this page).

Description of invention (13) 208 is The latch circuit inputs the contents of the shift register 207 due to the signal LP. 209 is a counting counter, and it has an up counter with the same number of bits as the intensity signal 10 ~ 13. The counter 209 is counted up by the correction clock 101. And due to the role of the LP number, the 210 is a consistent detection circuit. Each circuit 210 compares the output of the corresponding register of the barium circuit 208 with the output of the circuit 209 to detect whether they are consistent. If they become consistent, a control signal C2 that becomes active " 1 "is generated. At this time, if the content of the symbol multiple F (referred to as the control signal C 1) input to the temporary memory is a negative number (signal signal When F is active "1"), the bits of the shift register are reversed to detect whether it is consistent with the displayed value plus the value of 1. The detection result is kept until the next LP number is reached 211 is the conversion circuit, which will constitute 10 electrical SV0, V 1 U, V 1, V 1 L, V 2, V 3, V 4 U, V 4, V 4 L, V 5 , The voltages V 0, V4U, V4, U4L are divided into the 1¾ ® group, and the voltages V5, V1L VI, V1U are divided into the second voltage group, which is converted into one of the two groups according to the signal FR. , Assuming that “Press VO, V4U, V4, V4L are the first choice in the first group of pressure, can correct ®, correct choice (ϋ), non-selection ® ffi, correct the pressure of the Ministry of Economic Affairs Central Central Bureau printing (please first Read the notes on the back of the page and fill out this page) _Subscribe.

Description of the invention (丄 4) Corrected voltage (U), non-selected voltage, corrected low pressure (L). 212 is the level shift The device is composed of a multi-4 circuit 1 contact open. When the control multiple C0 becomes "1", each switch selects S1 and also selects the selected voltage. When the control signal C 0 becomes "0" and When the control multiple C 2 becomes " 1 ″, each switch selects S3. That is, the non-selected voltage is selected. When the control multiples C 0 and C 2 are both “0” and the control signal C 1 is “0”, each switch selects S2. If C1 is "1", then S4 is selected. The Y driver 205 has the above structure. The shift register 207 has a 5-bit structure due to the intensity signals 10 to 13 and the sign multiple F. However, the number of bits of the shift register 207 can also be appropriately increased or decreased by increasing or decreasing the number of bits of the intensity multiple. The number of registers constituting the shift registers 206 and 207, the number of latch circuits 208, and the number of detection circuits, and the number of openings constituting the level shifter are as shown in the circle equal to the second The number of scanning poles Υ1 ~ Υ6 in the LCD panel. The operation of the Y driver 205 will be described below. In Fig. 3, the double number DIN is input to the shift register 206 in synchronization with the double number LP and transmitted. As a result, the level shifter 212 and the corresponding one sequentially turn out the selective pressure. (In the future, the switch that generates the selected pressure will be called the selected switch, and the switch that turns out the other flute pressure will be called the unselected switch.) At this time, it will be synchronized with it, in one of the multiples LP. During the encounter period, the number YCSCL will increase the intensity by -1 6-A 4 (21UX 297 public issue) (please read the notes on the back and then fill out this page) 钤 ·, order. 201825 A6 B6 Central Standards Bureau of the Ministry of Economic Affairs Printed fifth, invention description (15) No. 10 ~ 13, the sign multiple is input to the shift register 207. Correction voltages (ϋ) to (L) are generated for each unselected reed, until the absolute value of the value represented by the intensity multiplier 10 to 13 and the value of the counter 209 up-counted by the correction clock become consistent until. The output correction voltage (U) or (L) is determined by the control multiple C1. In other words, Ye is determined by "0" or "1" under the sign signal. After the value of the counter 209 becomes the same, each unselected switch generates a non-selected electric charge. Therefore, the intensity signals 10 to 13 indicate The larger the absolute value of the value, the longer the correction voltage of the unselected open caster. The above describes the structure and operation of the Υ drive. In the second figure, 213 is the shift register 214 and the latch circuit 215. , And the double electrode driven by the level shifter 216 (hereinafter referred to as the X driver). The output of the level shifter 216 is introduced into each multiple electrode XI ~ Χ6 of the liquid crystal panel 201.

The TF / F circuit 401 is reset due to the function of the signal LP Set to generate " 0 ", the pair gate circuit 402L becomes the active input, and the pair gate 402U becomes the non-active round-robin. When the clock input formed by the multiplier XSCL is reversed, it corresponds to The data signals of the LCD panel 201 in Figure 2 are the even-numbered cells in XI ~ X6, and the data signals of X2, X4, and X6 enter the gate circuits 402U and 4 in Figure 4. At 02L, only the gate circuit 402L becomes active, and the data signal turns out. The output of the gate circuit 402U has nothing to do with the data signal and becomes non-active. On the contrary, when the second figure corresponds to the odd electrodes XI, X3, X5 When the multiple number enters the gate circuits 402U and 402L of FIG. 4, only the gate circuit 402U becomes active and outputs the data multiple number. The round of the gate circuit 402L becomes inactive regardless of the data signal. In other words, the 3-times circuit separates the data multiples associated with the electrode driven from the double electrode and the data multiples associated with the electrode driven from the bottom. These separated data multiples are called upper data multiples and lower data multiples, respectively. The counters 406U and 406L count the number of “1” states that are lit when each data multiple is separated. In other words, only when the output of the gate 402U, L becomes active when the multiple XSCL rises, The counters 506U and L are added. The result of the addition (assuming that the value is H 1 ο η, Μ 2 ο η) is synchronized with the number LP and is input to the latching circuits 407U and L respectively. Operation flute 4081] And 408L respectively perform the subtraction of the values of the latch circuits 407U, L (assuming this value is Ν10〇, Η2〇η) and the values Μ1οη, Μ2〇η of the counter 406U and L before the input moment. 9-(Please read the precautions on the back of Κ1 before filling in this page).

Description of Invention (25) Then, due to the function of the correction clock 110 When n = 3, the selected scan voltage + l becomes the scan voltage Y4. Therefore, the two levels of the level shifter 212 select S4 (correction voltage (L)) and S2 (correction voltage ( U), S4 (correction voltage S (L)), S1 (selection voltage), S4 (correction voltage (L)), S2 (correction voltage (U)), which are respectively supplied to the scanning electrodes Y1 ~ Y6 of the LCD panel 201 Select each switch of S2 to S4 to maintain this state. Until the correction clock 110 is cycled in the counter 209, corresponding to the number shown by the corresponding barium circuit 208, and the output of the counter 209 is respectively latched Until the numbers shown in circuit 2 08 become coincident. After becoming coincident, each Kailan selects S3 (non-selected voltage) and will take turns. The correction voltage (U) or (L) is used. The value is determined by whether the value I is positive or negative. The larger the absolute value of the value I, the longer the time for selecting the corrected voltage instead of the non-selecting voltage. In this way, the voltage is supplied to the scanning electrodes Y1 ~ Y6 of the liquid crystal panel 201. At this time, if the multiple-number electrodes XI ~ X6 are in When the display point formed on the selected scanning electrode Yn + 1 is lit, the X driver 213 supplies the lighting voltage to each multiple XI~Χ6, if unlit, the non-lighting voltage is supplied to each of the electrical problem, No. times XI~Χ6.

In the seventh circle (g), the solid line represents the voltage waveform applied to the scan electrode Y1, and the broken line represents the waveform distortion to be generated at the position of the display point D36. From the 7th circle (a) to (g), it can be seen that in the order of the scan electrodes Y1, Y2, Y3, the electrode located above is more affected by the change in the waveform of the swell pressure shown by the solid line in FIG. 7 (a). Large, and on the scanning electrodes Y1, Y2, Y3, a waveform distortion matching the size of the album is generated in the direction of the change of the electrical S waveform. Similarly, in accordance with the sequence of the scan electrodes Υ6, Υ5, Υ4 located below, the waveform of the size of the shadow is generated from below by the influence of the change of the voltage waveform of the multiplier electrodes Χ2, Χ4 supplied to the doubling voltage waveform distortion. As shown by the waveform shown by the * line in Figures 7 (b) ~ (g), the Y driver 205 in the 2nd sine is corrected in the direction opposite to the direction of the waveform distortion that will be generated in each scan Y1 ~ Y6. (U) or (L) replaces the non-selected flute pressure, and outputs it for the waveform code that will be generated at each broadcast scan pole ~ Y6.

The description of the invention ( 27) Increase and decrease according to the magnitude of the waveform distortion to be generated on each scan electrode Y1 ~ Y6. In other words, a longer time correction voltage is supplied to a larger distortion, and a shorter time correction voltage is supplied to a smaller distortion. Then, the non-selected voltage is supplied. Therefore, it is possible to substantially eliminate the distortion of the waveform to be generated in each of the scan electrodes Y1 to Y6. Therefore, there is no difference in the effective voltage applied to each display point of the liquid crystal panel 201, so that the display unevenness can be eliminated. As described above, when calculating the difference between the number of lights on the selected scan electrode and the next selected scan electrode, the position of the end portion where the display voltage is driven by the driving voltage waveform is considered, and according to the difference The amount of correction voltage applied to the scan electrodes on each electrode can eliminate display unevenness. [Embodiment 2] In Embodiment 1, a liquid crystal panel in which the double-numbered electrodes are alternately supplied with signal electric E waveforms from above and below is assumed. But it is also effective when supplied from only one party. For example, when supplying from the top only, as shown in Figure 4, it is sufficient to replace the output of T-F / F401 with the multiple of "1", which is always supplied to gates 402U and L. (This means the same as making each circuit 402, 406L to 410L in a non-operating state. Therefore, such a small road is not required. Incidentally, the circuit 405L is also unnecessary, and the round-off generated by 411L often becomes 0, so again The circuit 412 can be simplified. Therefore, the value I is I = (11 * 12) * f (k) According to this value I, perform the same operation as in Example 1, you can get the phase -29- (please read the precautions on the back before filling this page ) _ 梅 · , 定 ·. 线.

[Embodiment 3] In Embodiment 1, the liquid crystal panel in which the signal voltage waveform is supplied from only one side of the signal electrode is described, but it is also effective when supplied from both ends. When calculating the value I in Embodiment 1, As long as the function g (l KL / 2 1) is substituted for the function f (k), the calculation can be performed. At this time, the function g (X) is an increasing function that increases as the value X increases. By performing the same operation as in the first embodiment based on the numerical value I, the same effect can be obtained. In Embodiments 1 to 3, the method of adjusting the correction amount uses a method of keeping the voltage difference between the correction voltage and the non-selected voltage constant to increase or decrease the time for applying the correction voltage (hereinafter referred to as time axis correction). However, it is also possible to keep the time for applying the correction pressure constant, and change the difference between the correction pressure and the non-selected electrical IS (this action is voltage axis correction). You can also change the time and pressure of applying the correct pressure (this action is the time K-axis correction). You can also use the wave height value and the waveform represented by the exponential function that changes the required correction amount and the triangle waveform as the correction K (this action is the function waveform correction).

In the ring, 1101 ~ 1107 are series resistance. The voltage V0U.V5L is applied across it. These resistors 1101 to 1107 form a voltage divider circuit. The voltage generated by each resistor 1101 to 1107 is V0U, V0, V1, V2, V3, V4, V5, V5L from the top, then V ® V0-V1 = V1-V2 = V3-V4 = V4-V5 V2-V3 = a # V, where a is a constant of about 1 ~ 50.

The liquid crystal display device of the eighth circle has the structure as described above. The following describes the operation of this embodiment when the quadrangular shape is actually displayed. Figures 12 and 13 are circles showing the display contents displayed on the liquid crystal panel 201 of the ninth circle. In the figure, the dots in the diagonal line indicate lighting. In this example, Figure 12 and Figure 13 show that the same quadrangle is displayed on the left and right, respectively. The action is as follows. First, when the display in FIG. 12 or FIG. 13 is performed, the eighth correction circuit 804 divides the number of sticky bright spots on the scan electrodes Y1 to Y6 of the liquid crystal panel 201 in FIG. 12 or FIG.

Z '= 〇 + 〇 + 〇 + 〇 + 〇 + 〇 = 0 8th The corrected Xiaolu 804 in the figure only outputs the active correction multiple number 8 0 9 that matches the length of the value Z '. The power supply circuit 805 only rounds out the correction voltages V0U and V5L at the time when the correction signal 809 becomes active as the selection voltage to replace the voltages V0 and V5. • Hit. When the display in Figure 12 is displayed, the value Z 'of the scan electrodes Y2 ~ Y5 is less than the value when the display in Figure 13 is displayed. Therefore, when displaying the display in Figure 12, if the scan ~ Y5 is being selected, the correction voltages V0U and V5L become the selection voltages. The time of application is shorter than the display time in Figure 13. The Y driver 905 of Fig. 9 applies the selection voltage that varies according to the value Z ', and sequentially applies the selection voltage to the scanning electrodes Y1 to Y6 of the liquid crystal panel 201. The operation of the Y driver 213 is the same as that of the first embodiment, and its description is omitted. • Green · The Ministry of Economic Affairs Central Bureau of Precinct Printing performs the above operations, as shown in the example shown in Figure 12. If the lighting point is near the drive terminals of scan electrodes Y2 ~ Y5, the voltage on the scan® pole is matched The loss of the waveform is not too large, and a selective voltage with a small amount of correction voltage is supplied to the selected brush trace electrode. In other words, the flute pressure with a shorter application time is used as the filling flute®, instead of the correction box V0U, V5L being the pressure V0, V5 supplied to the pole. On the contrary, as shown in the display example in Figure 13, if the lighting point is faster than the drive end of the scan flute Y2 ~ Y5, A4 (210X 297 public) A6 B6 201825 V. Description of invention (38) (please Read the precautions on the back first and then fill out this page.) In conjunction with the larger distortion of the voltage waveform on the scan electrode, the selected voltage with a larger amount of correction voltage is supplied to the selected scan electrode. In other words. The voltage applied for a long time is used as the selection voltage, and instead of the modified voltage V 0 U, V 5 L becomes the voltage V 0, and the voltage of V 5 is supplied to the electrode. Therefore, the difference between the correction amounts can be roughly corrected based on the display positions in Figure 12 and Figure 13. As described above, when counting the number of lighting points on each scan electrode, the position of the lighting point is weighted and counted, and the selection voltage supplied to each electrode is changed according to the result. This eliminates display unevenness. [Embodiment 5] Order. Embodiment 4 shows that the liquid crystal panel in which the scanning voltage waveform is supplied from only one side of the scanning frost electrode has the same effect when supplied from both ends. In other words, in Example 4, when calculating the value Z ′, it is sufficient to substitute the function q (i) for the value P (| i -S / 2 |), and the function p (x) is when the value X increases The reduction function of extinction. Performing the operation as described in Embodiment 4 according to the value Z 'can produce the same effect. . Line · In Example 4, the adjustment method for the correction amount is to maintain the difference between the voltage V0U and V 0, the difference between the β V 5 and V 5 is constant, and the voltage V 0 U and V 5 L are selected as the choice. The method of pressure application time is also the method of real-time shaft correction. Others can also use flute pressure axis correction, time flute pressure axis correction, and function waveform correction method.
