Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
The invention provides a display method, which is applied to a display panel, wherein the display panel at least comprises a time sequence controller T-CON and a liquid crystal driving module, the time sequence controller is mainly used for processing input display signals such as LVDS signals to obtain corresponding scanning signals, data signals and control time sequence signals, and sending the scanning signals, the data signals and the control time sequence signals to the liquid crystal driving module so that the liquid crystal driving module drives liquid crystal through the scanning signals, the data signals and the control time sequence signals, and meanwhile, the time sequence controller is also used for providing reference voltage, gamma voltage, performing color correction and the like; referring to fig. 1, fig. 1 is a schematic flow chart showing a first embodiment of a method according to the present invention, the method includes the steps of:
step S10, acquiring a plurality of preset gray scales, and acquiring initial binding point voltages corresponding to the preset gray scales, wherein the preset gray scales at least comprise 0 gray scale and first gray scale, and the initial binding point voltage corresponding to the first gray scale is first binding point voltage; the first gray scale is 1 gray scale;
the preset gray scale is preset gray scale which needs to correspond to the binding point voltage; it should be noted that, based on different designs of the display panel, the number of preset gray levels and specific settings may be different, and in this embodiment and the subsequent embodiments, the number of preset gray levels is 7, and the preset gray levels are respectively 0 gray level, 1 gray level, 64 gray level, 128 gray level, 192 gray level, 254 gray level and 255 gray level; as can be seen from the preset gray level, in this embodiment, 8-bit color data is used for illustration, 0 gray level is the lowest gray level, and is represented as black in the gray level map, 255 gray level is the highest gray level, and is represented as white in the gray level map; therefore, on the basis of the present embodiment, if the method is applied to color data with other bits, such as 10-bit color data, the method can be set against 8-bit color data, and detailed description is omitted herein.
Binding each preset gray level with gamma voltage, performing voltage debugging on each preset gray level to obtain optimal gamma voltage, wherein the initial binding point voltage is the voltage value of the gamma voltage corresponding to the preset gray level after voltage debugging, and one initial binding point voltage comprises two voltage values; specifically, the gamma voltages in the embodiment are 14, and are GAM 1-14 respectively, and the voltage values of GAM 1-GAM 14 are sequentially reduced, wherein GAM1 and GAM14 correspond to 255 gray scales; GAM2 corresponds to GAM13 at a 254 gray level; GAM3 corresponds to 192 gray scales with GAM 12; GAM4 corresponds to 128 gray levels with GAM 11; GAM5 corresponds to 64 gray scales with GAM 10; GAM6 corresponds to GAM9 with 1 gray scale; GAM7 corresponds to GAM8 with 0 gray scale; the reference voltage is between GAM7 and GAM8; the first gray level in the present embodiment is the gray level closest to the 0 gray level, that is, the gray levels corresponding to GAM6 and GAM9, specifically, the first gray level in the present embodiment is 1 gray level. It should be noted that, the setting of the gamma voltage corresponding to the gray level is illustrated, and the setting of the resistor string of the data driving chip and the actual need may be correspondingly adjusted, which is not described herein.
Step S20, updating the binding point voltage corresponding to the 0 gray scale to the first binding point voltage;
the initial binding point voltage of 0 gray level corresponds to the initial binding point voltages of GAM7 and GAM8 and 1 gray level respectively, namely, the first binding point voltage corresponds to GAM6 and GAM9 respectively, and the binding point voltage corresponding to the 0 gray level is updated to be the first binding point voltage, namely, the binding point voltage of 0 gray level is bound to GAM6 and GAM9; at this time, the binding point voltages of 0 gray level and 1 gray level correspond to GAM6 and GAM9.
Step S30, after the updating is completed, performing a display operation based on the updated binding point voltages of the preset gray scales.
When the display is performed, the time sequence controller outputs the updated binding point voltages corresponding to the preset gray scales to a data driving chip in the liquid crystal driving module, a resistor string is arranged in the data driving chip to divide the input initial binding point voltages so as to obtain voltages corresponding to different gray scales, and then the voltages obtained by the division are selected and output according to data signals so as to drive the liquid crystal. The display operation is only described with respect to the driving principle of the data line, and other specific control contents in the display operation may be set according to actual application needs, which is not limited herein.
According to the embodiment, the initial binding point voltages corresponding to all preset gray scales are acquired first to ensure the elimination of the afterimage, and on the basis, the binding point voltages of 0 gray scales are bound to the initial binding point voltages of other first gray scales, so that the normal display of 0 gray scales is not affected when the initial binding point voltages of 0 gray scales are adjusted, the occurrence of horizontal crosstalk is avoided, and the display effect is further improved.
Further, in the second embodiment of the display method according to the present invention set forth in the first embodiment of the present invention, the step S20 includes the steps of:
step S40, obtaining a first calibration compensation value corresponding to the first gray scale;
and S50, updating the calibration compensation value corresponding to the 0 gray scale to the first calibration compensation value.
After the gamma voltage is set, the brightness change of gray scale can basically be ensured to meet the display standard, but the problems of inconsistent color temperature, color cast and the like still exist; in order to solve this problem, an ACC (Accurate Color Calibration, color correction technique) is set, and the ACC is a color correction technique for changing the gain values of the primary color components R, G, B, so that color correction can be performed on different gray scales, the consistency of the color temperature and the chromaticity coordinates is improved, and the calibration compensation value is the gain value in the ACC. It is understood that, for each gray level from 0 to 255, a calibration compensation value is corresponding, and a specific adjustment method of the calibration compensation value may be selected according to actual needs, which is not limited herein.
It can be understood that the display effect is commonly ensured by the gamma voltage and the setting of the ACC; because the binding point voltage of the 0 gray scale is updated to be bound with the GAM6 and the GAM9, if the initial calibration compensation value set on the basis of the GAM7 and the GAM8 is still adopted at this time, a certain error exists in the final display effect, and even the display requirement cannot be met, so that the calibration compensation value corresponding to the 0 gray scale is updated to be the first calibration compensation value set on the basis of the GAM6 and the GAM9, and the display effect of the 0 gray scale can be ensured.
According to the embodiment, the calibration compensation value corresponding to the 0 gray scale is synchronously adjusted, so that the display effect of the 0 gray scale can be ensured.
Further, in a third embodiment of the display method according to the present invention set forth in the first embodiment of the present invention, after the step S20, the method further includes the steps of:
step S60, if an afterimage experiment test instruction is received, acquiring an initial binding point voltage corresponding to the 0 gray scale;
and step S70, carrying out an afterimage experiment according to the afterimage experiment test instruction based on the initial binding point voltage corresponding to the 0 gray scale.
The afterimage experiment test instruction characterizes the starting of an afterimage experiment; when the liquid crystal display device displays a certain image for a long time and then displays other images, the residual charges exist at the two ends of the liquid crystal molecules, so that the liquid crystal display device is difficult to shift in time, the problem of residual images is caused, and the display effect is affected; the afterimage experiment is a process for detecting the problem. In general, an afterimage experiment determines the grade of an afterimage based on the brightness difference; specifically, firstly, determining a test image for testing, testing the actual brightness value of the liquid crystal display device when the test image is displayed, and continuously displaying a still image on the liquid crystal display device until an afterimage phenomenon appears, wherein the still image can be selected according to the actual application scene and the requirement, such as a chess board image; at this time, the test image is displayed again, and the current brightness value of the liquid crystal display device when displaying the test image in real time is detected again, and then the actual brightness value and the current brightness value are compared to determine the afterimage level of the liquid crystal display device. The above-mentioned residual image experimental mode is only used to illustrate the principle, and may be specifically set according to needs in practical application, and is not limited herein.
According to the principle of an afterimage experiment, the brightness is an important parameter in the afterimage experiment, and the gray scale is the representation of the brightness in display; meanwhile, the chess board image only contains 0 gray scale and 255 gray scales, namely black and white, and because the first binding point voltage of 0 gray scale and 1 gray scale is used for binding, if the afterimage experiment is directly carried out by the first binding point voltage, the result of the afterimage experiment is affected, in order to ensure the accuracy of the afterimage experiment, when the afterimage experiment is carried out, the 0 gray scale is bound with GAM7 and GAM8 again, and the afterimage experiment is carried out based on the 0 gray scale after binding.
Further, the step S70 includes the steps of:
step S71, updating the binding point voltage corresponding to the 0 gray scale to the initial binding point voltage corresponding to the 0 gray scale;
step S72, after updating, based on the updated binding point voltages of the preset gray scales, performing an afterimage experiment according to the afterimage experiment test instruction;
step S73, if the residual image experiment is completed, updating the initial binding point voltage corresponding to the 0 gray scale to the first binding point voltage again.
The initial binding point voltage corresponding to the 0 gray scale is GAM7 and GAM8 which are obtained through voltage debugging at first; finishing an afterimage experiment based on the 0 gray scale of the binding GAM7 and GAM8; if an afterimage experiment completion instruction is received, the afterimage experiment is considered to be finished, and display under the general condition is needed at the moment, so that the initial binding point voltage corresponding to the 0 gray scale is needed to be updated to the first binding point voltage again, namely, the 0 gray scale is bound with the GAM6 and the GAM9.
The embodiment can ensure the accuracy of the afterimage experiment.
Further, in a fourth embodiment of the display method according to the present invention set forth in the first embodiment of the present invention, the step S10 includes the steps of:
step S11, performing voltage debugging operation on each preset gray level to obtain a binding point voltage corresponding to each preset gray level, where the 0 gray level corresponds to a second binding point voltage, the second binding point voltage includes a first sub-voltage and a second sub-voltage, and the first sub-voltage is greater than the second sub-voltage:
step S12, performing a downshifting operation on the second sub-voltage to obtain a third sub-voltage, and updating the second binding point voltage into the first sub-voltage and the third sub-voltage;
and step S13, taking the updated binding point voltages as initial binding point voltages corresponding to the preset gray scales.
The voltage debugging operation is a process of debugging the binding point voltage of each preset gray level so that the displayed brightness meets the gamma curve standard when the preset gray level is displayed. After the voltage debugging operation is finished, when each preset gray level is displayed by the binding point voltage, the displayed brightness meets the gamma curve standard; the voltage of the second binding point is the voltage value of the GAM7 and the GAM8 bound with 0 gray scale, specifically, the first sub-voltage is the voltage value corresponding to the GAM7, and the second sub-voltage is the voltage value corresponding to the GAM8; because the existence of the Feed through voltage or the variation of the transistor characteristics can generate direct current offset (offsetDC), the voltage actually applied to the two ends of the pixel liquid crystal is asymmetric, and the problem of residual image occurs, in order to solve the problem, the voltage value of the GAM8 is reduced to reduce or eliminate the direct current offset caused by the Feed through voltage, so that the generation of the residual image is avoided; the third sub-voltage is the voltage value of GAM8 after the decrease. After the binding point voltage of the GAM8 is adjusted, the binding point voltage corresponding to each gray level is the initial binding point voltage, and when the display is performed based on the initial binding point voltage, the display brightness can be ensured to meet the gamma curve standard, and meanwhile, the generation of afterimages is avoided.
The embodiment can enable the display brightness to meet the gamma curve standard and avoid the generation of residual images.
Further, in a fifth embodiment of the display method according to the present invention set forth in the fourth embodiment of the present invention, the step S12 includes the steps of:
step S121, obtaining direct-current bias voltage;
step S122, subtracting the dc bias voltage from the second sub-voltage to obtain the third sub-voltage.
The DC bias voltage is the voltage value of DC offset generated by the existence of Feed through voltage or the variation of transistor characteristics; as can be seen from the foregoing features, in the embodiments of the present application, GAM7 and GAM8 are mainly used for performing an afterimage experiment, in the process of performing the afterimage experiment, due to the existence of the dc bias voltage, the actual reference voltage is shifted downward, and when the binding point voltage is set, the two gamma voltages of the same preset gray scale are set correspondingly to positive and negative polarities based on the reference voltage, so that the positive and negative polarities of the same preset gray scale are asymmetric based on the reference voltage, specifically, the absolute value of the negative polarity is smaller than the absolute value of the positive polarity, thereby affecting the display effect, and therefore, compensation of the negative polarity is required to restore the symmetry of the positive and negative polarities. Specifically, in this embodiment, the GAM8, that is, the second sub-voltage is reduced by the value of the dc bias voltage to compensate, so that the GAM7 and GAM8 are symmetrical based on the reference voltage, thereby ensuring the display effect.
The embodiment can avoid residual images and ensure the display effect.
Further, in a sixth embodiment of the display method according to the present invention set forth in the fourth embodiment of the present invention, the step S11 includes the steps of:
step S111, for each of the preset gray scales, obtaining corresponding actual brightness values under different gamma voltages;
step S112, obtaining the required brightness value of the preset gray scale, and taking the gamma voltage with the actual brightness value consistent with the required brightness value as the binding point voltage of the preset gray scale.
The actual brightness value is obtained by measuring through optical detection instruments such as a color analyzer when the preset gray level is displayed; specifically, each preset gray level is displayed in turn, when each preset gray level is displayed, the gamma voltage is continuously adjusted, after each adjustment, the actual brightness value is obtained, meanwhile, the actual brightness value is compared with the target brightness value of the preset gray level, when the difference between the actual brightness value and the target brightness value is within the allowable range, the current gamma voltage is used as the binding point voltage of the preset gray level, and then the next preset gray level is debugged until the binding point voltage is determined for all the preset gray levels. In other embodiments, the actual brightness values corresponding to all the gamma voltages at a certain preset gray level may be obtained, and the gamma voltage with the smallest difference between the actual brightness value and the target brightness value may be used as the binding point voltage of the preset gray level. It should be noted that, the above implementation method is only used as an implementation method for determining the binding point voltage, and the binding point voltage may be determined by other ways according to the actual application scenario and needs, which is not limited herein.
The embodiment can accurately obtain the binding point voltage corresponding to the preset gray level.
It should be noted that, for simplicity of description, the foregoing method embodiments are all expressed as a series of action combinations, but it should be understood by those skilled in the art that the present application is not limited by the order of actions described, as some steps may be performed in other order or simultaneously in accordance with the present application.
