Description
Technical Field
The invention relates to the field of equipment display, in particular to a liquid crystal display panel and a driving IC thereof.
Background
The TFT-LCD generally includes a color film substrate, an array substrate, and a liquid crystal layer sandwiched between the color film substrate and the array substrate, where the array substrate includes an effective display area formed by a pixel array, and further includes a data driving circuit (Source Driver) and a scan driving circuit (Gate Driver) outside the effective display area, and the data driving circuit and the scan driving circuit are respectively connected to each pixel to drive the pixel for displaying.
In addition, a circular liquid crystal display panel in which a plurality of pixels 30 are arrayed on an array substrate, a plurality of data signals are output from the driving IC10 through a plurality of data lines 20, respectively, and one data line is connected to data input terminals of one column of pixels is increasingly used in wearing products, as shown in fig. 1. However, since the array substrate is circular in shape, the pixels are not uniformly distributed in the column direction, and referring to fig. 2, the load on the corresponding data line is large when the number of pixels in the pixel column in the middle area of the array substrate is large, and the load on the corresponding data line is small when the number of pixels in the pixel column in the two end areas is small. If the driving ICs provide the same driving capability to the data lines in different areas on the array substrate, display non-uniformity may be caused, thereby affecting product yield.
In order to avoid such a situation of display unevenness due to load unevenness, the conventional method generally includes: impedance matching is achieved by adjusting the wiring mode of the data lines on the array substrate, loads of different areas are changed, for example, the middle area can reduce impedance (the wiring is shortened as much as possible or the wiring is widened), and the two sides can increase impedance (the wiring length is increased and the wiring width is reduced). In addition, the driving capability of the data line of the driving IC is enhanced to assist the adjustment. However, the method of adjusting the wiring of the data line has the following disadvantages:

3. the data line driving capability of the conventional driver IC can only be increased or decreased as a whole. When the non-uniformity is slight, the load difference of the data lines can be reduced by increasing the driving capability of the data lines, which has a better effect, but the power consumption of the driving IC is increased.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The color film substrate and the array substrate are arranged oppositely, and the liquid crystal layer is clamped between the color film substrate and the array substrate. The plurality of data lines correspond to the plurality of pixel columns one to one, that is, all pixels in one pixel column share one data line. The driving IC is provided with a plurality of output ends, each output end is connected with a data line, and the driving IC outputs corresponding data signals to each pixel column through the plurality of data lines respectively.
Fig. 3 is a logic structure diagram of a first embodiment of the driving IC of the present invention, when the array substrate is circular, the driving IC of this embodiment includes a signal generating module 11 and a signal adjusting module 12, where the signal generating module 11 is configured to generate a data signal corresponding to each pixel column; the signal adjusting module 12 is configured to adjust each data signal according to a position of each pixel row on the array substrate, so that after adjustment, the driving capability or the load of each data line is different, for example, the data line corresponding to the middle pixel row has a larger driving capability or a smaller resistance, and the data lines corresponding to the pixel rows on the two sides have a smaller driving capability or a larger resistance, and then, the adjusted data signals are input to the corresponding pixel rows.
By implementing the technical scheme of the embodiment, the driving IC can dynamically adjust the data signals on each data line according to the position of each pixel column on the array substrate, so that the problem of uneven display caused by uneven distribution of pixels of different pixel columns is solved, and compared with the existing method for matching impedance by changing a wiring mode on a panel, software simulation is not needed, and the time and the cost are saved; compared with the existing method of integrally increasing or reducing the driving capability of the data line, the power consumption of the driving IC is also saved.
Fig. 4A is a structural diagram of a first embodiment of a liquid crystal display panel according to the present invention, in which an array substrate includes a plurality of pixel columns arranged in parallel, and a driving IC10 'outputs a corresponding data signal to each of the pixel columns through a plurality of data lines 20', respectively. In connection with the driver IC10 'shown in fig. 4B, the signal adjusting module of the driver IC 10' includes power amplifiers 121 corresponding to the respective pixel columns one to one. With reference to fig. 4C, the same-direction input end of the power amplifier is connected to a corresponding output end (not shown) of the signal generating module, the output end of the power amplifier is connected to a corresponding pixel column through a corresponding data line, and the gain value of the power amplifier is related to the position of the corresponding pixel column on the array substrate, with reference to fig. 4D, when the pixel column is closer to the middle area of the array substrate, the gain value of the corresponding power amplifier is larger, and when the pixel column is closer to the areas at the two ends of the array substrate, the gain value of the corresponding power amplifier is smaller, so that the driving capability of each data line is dynamically adjustable, which is different from the prior art that the driving capability of the data line can only be integrally adjusted to be larger or smaller.
In a preferred embodiment, the driver IC further includes a configuration module, and the configuration module is configured to configure the signal adjusting module according to preset configuration information. For example, the configuration information is a gain value of the power amplifier, and the gain value of the power amplifier can be stored in the corresponding register, so that the adjustment of the driving capability of the corresponding data line can be realized by adjusting the gain value in the corresponding register.
Further, in order to reduce the number of registers in the driver IC, only the configuration information of a part of the pixel columns may be stored, and the configuration information of the other pixel columns may be obtained by calculation. Specifically, the configuration module is configured to calculate second configuration information corresponding to other pixel columns according to first configuration information corresponding to a preset part of pixel columns, and configure the signal adjustment module according to the first configuration information and the second configuration information. In addition, the driving IC may further include a receiving module configured to receive first configuration information corresponding to a part of the pixel columns, which is written in advance by a user (designer), and store the first configuration information in a corresponding register. Referring to fig. 4E, for example, there are 101 pixel columns and 101 data lines, the 101 pixel columns are sequentially numbered from left to right as 1, 2, 3,.. and 101, and the designer can set only the gain value corresponding to the 4i +1 th pixel column by writing an instruction to the driver IC, i is 0,1, 2,.. and 25, i.e., the selected pixel columns are distributed on the array substrate, only 26 registers are needed, while the gain values corresponding to the remaining pixel columns can be obtained by calculation, the gain values corresponding to the other pixel columns are preferably calculated by using a linear interpolation method, for example, a2 ═ a5-a1)/4+ a1, wherein, a1 is the gain value of the power amplifier corresponding to the first pixel row, a2 is the gain value of the power amplifier corresponding to the second pixel row, and a5 is the gain value of the power amplifier corresponding to the fifth pixel row. Through the technical scheme of the embodiment, a designer does not need to set the gain value of each power amplifier, and only needs to adjust the gain values of part of the nodes.
Finally, it should be noted that, to simplify the calculation process, the gain values corresponding to the pixel columns may be normalized, that is, the maximum gain value is set to 1, and at this time, the gain values corresponding to all the pixel columns are all one value in the range of 0 to 1.
Fig. 5A is a structural diagram of a second embodiment of the liquid crystal display panel according to the present invention, in which the array substrate includes a plurality of pixel columns arranged in parallel, and the driving IC10 ″ outputs a corresponding data signal to each of the pixel columns through a plurality of data lines 20 ″. In connection with the driving IC10 ″ shown in fig. 5B, the signal adjusting module of the driving IC10 ″ includes variable resistors 122 corresponding to the respective pixel columns one to one. With reference to fig. 5C, one end of the variable resistor is connected to the corresponding output end of the signal generating module, and the other end of the variable resistor is connected to the corresponding pixel row through the corresponding data line, and the resistance value of the variable resistor is related to the position of the corresponding pixel row on the array substrate, with reference to fig. 5D, when the pixel row is closer to the middle area of the array substrate, the resistance value of the corresponding variable resistor is smaller, and when the pixel row is closer to the areas at the two ends of the array substrate, the resistance value of the corresponding variable resistor is larger, thereby realizing dynamic adjustment of the load of each data line, which is different from the fact that the load of the data line in the prior art can only be fixed to a certain specific value.
In a preferred embodiment, the driver IC further includes a configuration module, and the configuration module is configured to configure the signal adjusting module according to preset configuration information. For example, the configuration information is the resistance value of the variable resistor, the configuration information can be stored in the register, and the adjustment of the load size on the corresponding data line can be realized by adjusting the resistance value in the register.
Further, in order to reduce the number of registers in the driver IC, only the configuration information of a part of the pixel columns may be stored, and the configuration information of the other pixel columns may be obtained by calculation. Specifically, the configuration module is configured to calculate second configuration information corresponding to other pixel columns according to first configuration information corresponding to a preset part of pixel columns, and configure the signal adjustment module according to the first configuration information and the second configuration information. In addition, the driving IC may further include a receiving module, where the receiving module is configured to receive first configuration information corresponding to a part of the pixel columns, which is written in advance by a user (designer), and store the first configuration information in a corresponding register. Referring to fig. 5E, for example, there are 101 pixel columns and 101 data lines, the 101 pixel columns are sequentially numbered from left to right as 1, 2, 3,.. and 101, the user can set the resistance value corresponding to the 4i +1 th pixel column only by writing an instruction to the driving IC, i is 0,1, 2,.. and 25, that is, the selected pixel columns are distributed on the array substrate, and in this case, only 26 registers are needed, the resistance values of the remaining pixel columns can be obtained by calculation, and preferably, the resistance values of the other pixel columns are calculated by using a linear interpolation method, for example, R2 ═ R1- (R1-R5)/4, wherein, R1 is the resistance of the variable resistor corresponding to the first pixel row, R2 is the resistance of the variable resistor corresponding to the second pixel row, and R5 is the resistance of the variable resistor corresponding to the fifth pixel row. Through the technical scheme of the embodiment, a designer does not need to set the resistance value of each variable resistor, and only needs to adjust the resistance values of partial nodes.
Finally, it should be noted that, to simplify the calculation process, the resistance values corresponding to the pixel columns may be normalized, that is, the maximum resistance value is set to 1, and at this time, the resistance values corresponding to all the pixel columns are all a value in the range of 0 to 1.
On the basis of the above embodiment, further, the driving IC of the present invention may further include an OTP memory for storing configuration information, so that the configuration information can be fixed in the driving IC after the trimming is completed, and is not lost even if power is turned off, thereby enabling the trimming to be completed at a factory once, and the panel can be normally used without any modification at a user side.
Still further, the driving IC of the above embodiment may be used in combination with panel wiring, that is, the length of the data line corresponding to the pixel columns on the two sides of the array substrate is greater than the length of the data line corresponding to the pixel column in the middle, and/or the width of the data line corresponding to the pixel columns on the two sides of the array substrate is less than the width of the data line corresponding to the pixel column in the middle. Thereby more finely and accurately achieving load matching.
