In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
In the description of the present application, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying a number of the indicated technical features. Thus, features defined as "first" and "second", etc. may explicitly or implicitly include one or more of the described features and are therefore not to be construed as limiting the application.
The embodiment of the application provides a display device and a method for improving crosstalk of the display device. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic view illustrating a first structure of a display device according to an embodiment of the present disclosure. As shown in fig. 1, the display device 10 provided in the embodiment of the present application includes a plurality of first color film substrate common voltage lines 101 arranged along a first direction X, a detecting module 102, and an addressing module 103.
The abnormal color film substrate common voltage line is a first color film substrate common voltage line 101 on which a color film substrate common voltage fluctuates.
The detecting module 102 is configured to detect whether a common voltage of the color film substrate fluctuates. The detecting module 102 is configured to determine position information of the abnormal color film substrate common voltage line when the color film substrate common voltage fluctuates, and adjust the color film substrate common voltage of the abnormal color film substrate common voltage line in a next frame, so as to improve a crosstalk phenomenon of the display device 10.
It should be noted that, in the implementation of the present application, according to the fluctuation value of the common voltage of the color filter substrate detected by the detecting module 102, the fluctuation of the common voltage of the color filter substrate on the common voltage line of the abnormal color filter substrate can be cancelled out by an opposite fluctuation value in the next frame, so as to achieve the effect of improving the crosstalk phenomenon of the display device 10. Specifically, the adjustment process is in a blank period between the current frame and the next frame.
It should be noted that, the values of the common voltage fluctuation of the color filter substrate for each frame of the abnormal color filter substrate common voltage line are the same. Therefore, the compensation information can be obtained according to the information of the display picture of the current frame, and the compensation information is adopted to adjust the color film substrate common voltage on the color film substrate common voltage line of the abnormal color film substrate of the next frame, so that the crosstalk phenomenon of the display device 10 is improved, and the display quality of the display device 10 is improved.
In the embodiment of the present application, when the crosstalk phenomenon occurs in the display device 10, the specific position where the crosstalk phenomenon occurs, that is, the first color film common voltage line where the color film common voltage fluctuates, may be determined by the address selecting module 103, so that the abnormal display area where the crosstalk phenomenon occurs is compensated accurately without affecting other display areas.
It should be noted that, in the embodiment of the present application, the crosstalk phenomenon of the display device 10 is improved by precisely adjusting the color film substrate common voltage of the abnormal color film substrate common voltage line, instead of adjusting the color film substrate common voltage in a whole plane, so that the fluctuation value of the color film substrate common voltage of the abnormal color film substrate common voltage line can be precisely offset, and the effect of improving the crosstalk phenomenon of the display device 10 is achieved without affecting the display effect
In addition, in the embodiments of the present application, the crosstalk phenomenon of the display device 10 is improved by directly adjusting the common voltage of the color film substrate, instead of adjusting the voltage difference between the gamma voltage and the common voltage of the color film substrate according to the data line, so that the defect of asymmetric positive and negative voltages of the voltage is avoided.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a change of a common voltage of a color filter substrate in a display device according to an embodiment of the present disclosure.
It should be noted that the crosstalk phenomenon of the display device is caused by fluctuation of a real-time color film substrate common voltage (CFCOM) of the display device. Specifically, as can be seen from fig. 3, when a transition occurs from one gray scale to another gray scale, the real-time color filter substrate of the display device fluctuates, so that the luminance of the area is different from that of the other areas, and thus a crosstalk phenomenon occurs in the area, where the luminance is darker or brighter. Therefore, whether the crosstalk phenomenon occurs in the display device 10 can be determined by detecting whether the common voltage of the color film substrate fluctuates by the detecting module 102.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a crosstalk phenomenon occurring in the display device according to the embodiment of the present disclosure.
As can be seen from fig. 3, the crosstalk phenomenon may be determined by recognizing the screen with the human eye, or by determining whether the crosstalk phenomenon occurs in the display device 10. Whether the crosstalk phenomenon occurs in the display device 10 is judged by detecting whether the common voltage of the color film substrate fluctuates, and firstly, when the common voltage of the color film substrate fluctuates slightly, the crosstalk phenomenon is not obvious; the second reason is that when the crosstalk phenomenon of the display device 10 is improved, the crosstalk phenomenon also needs to be improved according to the real-time voltage information of the common voltage of the color film substrate.
Referring to fig. 4, fig. 4 is a circuit diagram of a detection module according to an embodiment of the present disclosure.
As can be seen from fig. 4, the detection module provided in the embodiment of the present application includes a comparison circuit, and the comparison circuit compares the real-time color filter substrate common voltage with the reference color filter substrate common voltage to determine whether the real-time color filter substrate common voltage fluctuates due to coupling of other signal lines.
In addition, it should be noted that, because the real-time color filter substrate common voltage is stable and unchanged in one frame, whether the waveform of the real-time color filter substrate common voltage decreases or increases can be directly detected, and whether the color filter substrate common voltage fluctuates can also be determined.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a second structure of a display device according to an embodiment of the present disclosure. As shown in fig. 5, the display device 10 shown in fig. 5 is different from the display device shown in fig. 1 in that: the display device 10 further includes a plurality of second color film substrate common voltage lines 104 arranged along a second direction Y, and the second direction Y is staggered with the first direction X.
Wherein the first direction X and the second direction Y are perpendicular. Specifically, the first direction X is a horizontal direction, and the second direction Y is a vertical direction; or the first direction X is a vertical direction and the second direction Y is a horizontal direction.
It should be noted that, by setting the first color film substrate common voltage line 101 and the second color film substrate common voltage line 104 which are arranged perpendicularly to each other, the color film substrate common voltage lines are arranged in a mesh manner, so that not only the transmission condition of the color film substrate common voltage in the horizontal direction can be obtained, but also the transmission condition of the color film substrate common voltage in the vertical direction can be obtained, thereby not only achieving the effect of improving horizontal crosstalk, but also achieving the effect of improving vertical crosstalk, and further improving the display quality of the display device 10.
Referring to fig. 6, fig. 6 is a third structural schematic diagram of a display device according to an embodiment of the present disclosure. As shown in fig. 6, the display device 10 shown in fig. 6 is different from the display device shown in fig. 1 in that: addressing module 103 includes a first addressing sub-module 1031 and a second addressing sub-module 1032.
The first addressing submodule 1031 is configured to, when the common voltage of the color film substrate fluctuates, determine position information of the first color film substrate common voltage line 101 where the common voltage of the color film substrate fluctuates. The second addressing submodule 1032 is configured to confirm the position information of the second color filter substrate common voltage line 104 where the color filter substrate common voltage fluctuates when the color filter substrate common voltage fluctuates.
In the embodiment of the present application, two addressing sub-modules are provided to improve the crosstalk phenomenon of the display device 10. Specifically, the crosstalk phenomenon of the display device 10 in the first direction X is improved by the first addressing sub-module 1031, the crosstalk phenomenon of the display device 10 in the second direction Y is improved by the second addressing sub-module 1032, the two improvement processes are not interfered with each other, and can be performed simultaneously, so that the effect of improving the crosstalk phenomenon of the display device 10 can be more effectively achieved, and the display quality of the display device 10 can be further improved.
Referring to fig. 7, fig. 7 is a fourth structural schematic diagram of a display device according to an embodiment of the present application. As shown in fig. 7, the display device shown in fig. 7 is different from the display device shown in fig. 3 in that: addressing module 103 also includes an adjustment module 1033.
The adjusting module 1033 is configured to adjust the color film substrate common voltage of the abnormal color film substrate common voltage line in the next frame, so as to improve the crosstalk phenomenon of the display device 10.
Referring to fig. 8, fig. 8 is a fifth structural schematic diagram of a display device according to an embodiment of the present disclosure. As shown in fig. 8, the display device 10 shown in fig. 8 is different from the display device shown in fig. 1 in that: the display device 10 also includes a feedback module 105.
The feedback module 105 is configured to feed back the interval time from the start of outputting the common voltage to the occurrence of fluctuation to the addressing module 103, so that the addressing module 103 determines the position information of the common voltage line of the abnormal color film substrate.
It should be noted that, the color filter substrate common voltage of the display device is sequentially output line by line, so that the position information of the first color filter substrate common voltage line 101 corresponds to the transmission time of the color filter substrate common voltage, and when the color filter substrate common voltage is transmitted to a certain position of a certain first color filter substrate common voltage line 101, that is, the position information of the color filter substrate common voltage is stored in the storage module 107 in advance. Therefore, according to the interval time from the start of outputting the common voltage of the color film substrate to the occurrence of fluctuation, the position information of the common voltage of the color film substrate corresponding to the interval time can be extracted from the storage module 107, that is, the position information of the common voltage line of the abnormal first color film substrate is obtained.
Referring to fig. 9, fig. 9 is a sixth structural schematic diagram of a display device according to an embodiment of the present disclosure. As shown in fig. 9, the display device 10 shown in fig. 9 is different from the display device shown in fig. 1 in that: the display device also includes a fine tuning module 106.
The fine tuning module 106 is configured to, when the fluctuation of the common voltage of the color filter substrate is smaller than a preset value, adjust the voltage value of the common voltage line of the abnormal color filter substrate and output the voltage value to the next frame, so as to improve the crosstalk phenomenon of the display device 10.
Wherein the preset value is 2%.
It should be noted that when the fluctuation of the common voltage of the color filter substrate is within 2%, or the real-time common voltage of the color filter substrate is equal to the variation of the common voltage of the reference color filter substrate within 2%, the fine-tuning module 106 may be used to automatically adjust the common voltage of the color filter substrate to improve the crosstalk phenomenon. When the fluctuation of the common voltage of the color film substrate is large, the crosstalk phenomenon needs to be improved by artificially adjusting the common voltage of the color film substrate corresponding to the abnormal common voltage of the first color film substrate through software.
Referring to fig. 10, fig. 10 is a schematic diagram of a seventh structure of a display device according to an embodiment of the present disclosure. As shown in fig. 10, the display device 10 shown in fig. 10 is different from the display device shown in fig. 1 in that: the display device 10 further comprises a memory module 107.
The storage module 107 is configured to store position information of a common voltage of the color film substrate and reference voltage information.
It should be noted that, in the embodiment of the present application, it is necessary to cancel out the fluctuation value of the common voltage of the color filter substrate to improve the crosstalk phenomenon of the display device 10. Therefore, the information of the common voltage of the normal color film substrate on the abnormal common voltage line of the first color film substrate, that is, the information of the reference voltage of the common voltage of the color film substrate on the abnormal common voltage line of the first color film substrate, is needed, so as to calculate the fluctuation value of the common voltage of the color film substrate.
Referring to fig. 11, fig. 11 is an eighth structural schematic diagram of a display device according to an embodiment of the present application. As shown in fig. 11, the display device 10 shown in fig. 11 is different from the display device shown in fig. 10 in that: the display device 10 also includes a calculation module 108.
The calculating module 108 is configured to calculate compensation information required for adjusting the common voltage of the color film substrate according to the real-time voltage information of the common voltage of the color film substrate and the reference voltage information.
It should be noted that the crosstalk phenomenon occurs in the display device, which is a phenomenon that the display device has unequal brightness when the gray scale jumps because the real-time voltage of the color film substrate common voltage received by the display device is different from the reference voltage of the color film substrate common voltage. Therefore, the crosstalk phenomenon of the display device can be improved as long as the real-time voltage of the color film substrate common voltage received by the display device is the reference voltage of the color film substrate common voltage. Therefore, the effect of improving the crosstalk phenomenon of the display device 10 can be achieved only by obtaining the difference between the real-time voltage of the color film substrate common voltage on the abnormal first color film substrate common voltage line and the reference voltage of the color film substrate common voltage, and adding the difference to the color film substrate common voltage on the abnormal first color film substrate common voltage line of the next frame, so that the real-time voltage value of the color film substrate common voltage on the abnormal first color film substrate common voltage line of the next frame is the reference voltage value of the color film substrate common voltage on the abnormal first color film substrate common voltage line.
