Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for adjusting brightness of a display panel according to a first embodiment of the present invention.
Step S10: upon receiving the data transmission signal, input display data and output display data are acquired.
It can be understood that the data transmission signal may be a signal obtained by analyzing the input display data detected by the control chip by the liquid crystal panel, and after the input display data is received by the liquid crystal panel, a storage area may be divided for storing the input display data.
The input display data can be used for controlling the display of each pixel in the display panel to realize the display of images, the output display data is a group of data obtained after the input display data is transmitted to the data lines on the glass substrate in the display panel through the chip on film, and because the input display data passes through the fan-shaped lead wires on the glass substrate, the influence degrees of different impedances of the fan-shaped lead wires on the input display data of different data transmission channels are different, so that the output display data of each data transmission channel is different.
Step S20: and determining a current display panel gray scale value according to the output display data, and determining a chopping scale parameter according to the current display panel gray scale value.
It should be noted that, after the dividing of the luminance level of the display panel, the current panel gray-scale value may be a value corresponding to the luminance level of each pixel point at the position of the divided luminance level, because the more levels divided in the dividing of the gray-scale value, the finer the image displayed by the display panel is, in this embodiment, the dividing of the gray-scale value may be 512 levels, that is, 512 gray-scales in total, or other luminance level divisions, which is not limited in this embodiment.
It can be understood that, due to the influence of the fan-shaped lead impedance on the display data, the output display data corresponding to each data transmission channel is different, that is, in the actual display process, the brightness of each pixel point displayed by the display panel is also different, and the current display gray scale value of the corresponding pixel point can be determined according to the different output display data.
In specific implementation, in order to solve the problem of uneven display brightness of the display panel, the current display brightness condition of the display panel can be visually represented through the gray scale value of the current display panel, and the hacking parameter of specific hacking operation can be determined according to the current display brightness condition; wherein, the chopping order parameter comprises: the chopping period and the chopping value.
Step S30: and performing chopping processing on the input display data according to the chopping parameter to obtain target display data, and outputting the target display data.
It should be noted that the target display data is the display data obtained by performing the hacking process on the input display data according to the hacking parameter, and when the target display data is transmitted to the data line on the glass substrate in the display panel through the flip chip, the charging waveform near the COF center region is better due to the lower impedance at the center position of the fan-shaped region, and the corresponding picture brightness is higher, and the target display data corresponding to the center position obtained after the hacking process is smaller than the previous input display data, so that the charging rate at the COF center region is reduced, and the corresponding display picture brightness is also reduced.
Meanwhile, due to the fact that the impedance of the data lines is high and the charging waveform is poor, when the input display data in the area are cut down, the corresponding cut-down parameter is small, the input display data in the areas on two sides of the COF are enabled to be changed slightly or kept unchanged, at the moment, due to the fact that the brightness of the central area of the COF is reduced, the brightness change of the areas on two sides of the COF is small, and the problem that the brightness of a display picture of the display panel is not uniform can be solved.
In a specific implementation, if the input display data is 512, after the transmission, the output display data in the central area of the COF is 512, and the output display data bits 508 affected by the impedance are received in the areas on both sides of the COF, the input display data in the central area of the COF is reduced to obtain the target display data of the central area of the COF after the reduction is 508, and at this time, the output display data in the central area of the COF after the reduction is 508, and at this time, the display panel does not have the problem of display non-uniformity.
In this embodiment, when a data transmission signal is received, input display data and output display data are acquired, a gray scale value of a current display panel is determined according to the output display data, a chopping parameter is determined according to the gray scale value of the current display panel, chopping processing is performed on the input display data according to the chopping parameter, target display data is obtained, and the target display data is output. According to the display panel, the gray scale value of the current display panel is determined through the output display data, the corresponding chopping parameter is determined according to the gray scale value based on the current display panel, and finally, the chopping processing is performed on the input display data according to the chopping parameter, so that the charging rate of the central area of the display panel is reduced, and the technical problem that the brightness of the middle area of the display panel is reduced to the areas on two sides continuously due to different impedances of lead wire sets is solved.
Referring to fig. 2 and fig. 2 are schematic flow charts of a second embodiment of a method for adjusting brightness of a display panel according to the present invention, based on the first embodiment shown in fig. 1, in this embodiment, step S20 includes:
step S201: and determining the gray scale value of the current display panel according to the output display data, and determining corresponding data transmission channel information according to the gray scale value of the current display panel.
It is understood that the data transmission channel information may be data transmission channel number information of the fan-shaped lead region of the display panel, output display data values corresponding to different channels, and the like, wherein there is a correspondence relationship between the data transmission channels, the output display data values, and gray-scale values corresponding to the data transmission channels, and may be stored in the divided storage regions corresponding to the input display data.
Step S202: and determining a chopping order parameter based on the current display panel gray-scale value and the data transmission channel information.
The order chopping parameter includes a order chopping period and a order chopping value, and the order chopping period is used for dividing the data transmission channels so that the data transmission channels corresponding to the pixel points with the slightly different gray-scale values are chopped together; the chopping value is used for processing the input display data corresponding to the data transmission channel, so that the input display data corresponding to the data transmission channel meets the requirement of uniform brightness of the display panel.
Further, in order to accurately obtain the chopping level period and the chopping level value, the step S202 further includes:
extracting the number of data transmission channels in the data transmission channel information;
determining a chopping period according to a preset grouping rule and the number of the data transmission channels;
and determining a target chopping level value based on the chopping level period and the current display panel gray level value.
It is understood that the predetermined grouping rule may be that the gray-scale values are not greatly different, and the adjacent data transmission channels are divided into a group.
In a specific implementation, the chopping period T is a set of multiple channels determined according to a preset grouping rule and the number of data transmission channels, for example: taking 96 channel sets as a period and the like; secondly, the target chopping level value can be determined according to the difference between the gray level values and the number of the divided data transmission channel sets, for example: the gray scale value of the central region of the display panel is 500 at most, and the minimum value of the two side regions of the display panel is 400, at this time, the target cut-down scale value can be recorded as 10.
In the second embodiment, step S30 includes:
step S301: and grouping the data transmission channels according to the chopping period to obtain a data transmission channel set.
It should be noted that, when the display panel displays an image, the brightness difference between adjacent gray scale values cannot be seen by naked eyes generally, and each data transmission channel is clipped, so that the gray scale values corresponding to each data transmission channel are the same, and the workload is too large.
In a specific implementation, the data transmission channel set is obtained by grouping data transmission channels according to a hacking period, and is used for performing hacking processing based on a subsequent set unit, for example: the number of data transmission channels in the display panel is 960, and the hacking period T is determined to be 96 channels according to the actual number of the data transmission channels and a preset grouping rule, that is, 960 data transmission channels are divided based on 96 channels in the hacking period, so as to obtain a set of 10 data transmission channels.
Step S302: and acquiring the position information of the data transmission channel set in the display panel.
It can be understood that, referring to fig. 3, 10 is a control chip, 20 is a connecting lead, 30 is a fan-shaped lead, and 40 is a display screen; the image display in the display panel is usually connected to a set of fan-shaped leads on the substrate by a set of connecting leads using a COF, each lead corresponds to one of the wires in the fan-shaped lead, and because the fan-shaped leads are fan-shaped as a whole, the impedance of the data transmission channel in the middle area of the display panel is smaller, so that during the chopping processing of the display data corresponding to the data transmission channel set, the corresponding chopping value can be determined according to the position information of the data transmission channel set in the display panel.
Step S303: and performing order chopping processing on input display data corresponding to the data transmission channel set based on the target order chopping value and the position information to obtain target display data, and outputting the target display data.
It should be understood that after the position information of the data transmission channel set in the display panel is obtained, the data transmission channel set may be further sorted based on the position information to obtain the sorting sequence number of the data transmission channel set, the input display data corresponding to the data transmission channel set is subjected to the rank-chopping processing based on the target rank-chopping value and the sorting sequence number to obtain the target display data, and the target display data is output to the display area data line in the display panel, that is, sent to the sector lead of the display area.
Further, in order to perform accurate chopping processing on each data transmission channel set to obtain corresponding target display data, step S303 includes:
acquiring a target data transmission channel set in the data transmission channel set;
determining a data output turning channel set and a turning sequencing sequence number corresponding to the data output turning channel set according to the sequencing sequence number and the data transmission channel set;
subtracting the target chopping order value of the fold of the turn sequencing sequence number from the input display data to obtain turn channel input display data;
and performing order chopping processing on input display data corresponding to the target data transmission channel set based on the target order chopping value and the turning channel input display data to obtain target display data, and outputting the target display data.
It should be understood that the target set of data transmission channels may be a set of data transmission channels that require a chopping process.
It should be noted that, when the display panel displays an image, the impedance of the middle area of the display panel is small, and the display brightness is high, so the chopping value is larger when the data transmission channel set in the middle area of the display panel is chopped; the impedance of the two side regions of the display panel is relatively large, and the display brightness is relatively low, so that the chopping value when the data transmission channel sets of the two side regions of the display panel are subjected to chopping processing is smaller, and referring to fig. 4, when the chopping processing is performed on the display data corresponding to the display panel, the chopping value is first increased and then decreased, and a certain linear relationship is formed.
The method comprises the steps that a highest point exists in the target hacking order value changing process, and in the actual hacking order process, the changing rule of the target hacking order value can be determined through acquiring a data transmission turning channel set corresponding to the highest point of the target hacking order value and a turning sequencing sequence number corresponding to a data output turning channel set, and through the size relation between the target sequencing sequence number corresponding to the target data transmission channel set and the turning sequencing sequence number.
In a specific implementation, it may be determined whether a target sorting order number corresponding to the target data output channel set is smaller than the turning sorting order number, and if the target sorting order number is smaller than the turning sorting order number, it may be determined that a target chopping order value is continuously increased and has a certain linear relationship, for example: the data transmission channels of the conventional COF are 960 channels, the chopping period T is 96, the target chopping value is 2, and the corresponding sequence number of the turning sequence corresponding to the set of turning data transmission channels is 5 or 6, when it is detected that the current row display data value is 512, after the chopping processing unit processes the display data, the target chopping value corresponding to the set of target data transmission channels with the sequence number less than 5 should be continuously increased, that is, the channels 1 to 96 of the COF are the first set of data transmission channels, that is, the corresponding display data is 512, the channels 97 to 192 are the second set of data transmission channels, and the corresponding display data is 510.
If the target sequence number is greater than the turn sequence number, it may be determined that the target cut-off level value is continuously decreased, where the target cut-off level value corresponding to the target data transmission channel set with the sequence number greater than 6 should be continuously decreased, that is, the channels 769 to 864 are the ninth data transmission channel set, the corresponding display data is 510, the channels 865 to 960 are the tenth data transmission channel set, and the corresponding display data is 512.
In this embodiment, when a data transmission signal is received, input display data and output display data are acquired, a gray scale value of a current display panel is determined according to the output display data, corresponding data transmission channel information is determined according to the gray scale value of the current display panel, a chopping parameter is determined based on the gray scale value of the current display panel and the data transmission channel information, the input display data are chopped according to the chopping parameter to obtain target display data, and the target display data are output. According to the method and the device, the gray scale value of the current display panel is determined through output display data, corresponding data transmission channel information is determined according to the gray scale value of the current display panel, a hacking period can be determined according to the number of the data transmission channels, the data transmission channels are divided according to the hacking period, hacking processing is uniformly performed, the purposes of reducing workload and improving efficiency are achieved, finally, input display data corresponding to all data transmission channel sets are hacked according to a target hacking value, therefore, the central area charging rate of the display panel is reduced, and the technical problem that due to different impedances of lead wire sets, the brightness of the middle area of the display panel is continuously reduced to the two side areas, and the display is uneven is avoided.
