The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for purposes of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been shown in detail to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
First embodiment: as shown in fig. 1, fig. 1 is a shunt circuit of a display device provided herein, where the shunt circuit includes at least one scan voltage output module, the at least one scan voltage output module includes a target scan voltage output module, and the target scan voltage output module includes: the main current sub-module 10 is configured to receive an input display device scan voltage and output the scan voltage to the shunt sub-module; and the shunt sub-module 20 is electrically connected with the main current sub-module and is used for receiving the display equipment scanning voltage output by the main current sub-module and carrying out shunt output.
When the display device is controlled by the scanning voltage to display, a dark area with bright blocks and low gray level pictures exists, namely a high contrast coupling phenomenon, and the phenomenon occurs due to the fact that the instantaneous current is increased, so that the potential at the scanning voltage is influenced by a brighter area in the display device, the potential becomes higher, the voltage across two ends of LEDs in the same-row blue area is reduced, and the pictures are darker than those in the display area of the same row of non-display devices. In addition, because the number of LEDs used in the mini-LED technology is far more than that of a general display device, the area of a dark area of a picture in the display device is larger, and in order to solve the problem, a current dividing sub-module can be added at a main current position where a scanning voltage enters and exits and is used for reducing the potential increased due to the instantaneous increase of current, so that the problem that the picture is dark due to the excessively high potential is solved.
That is, according to the shunt circuit of the display device provided by the embodiment, a shunt submodule is added on the basis of the main current voltage end, and through the function of shunt, the potential of the input end of the main current voltage, which is increased due to the instantaneous increase of current, is reduced, so that the situation that the picture of the display device is dark is avoided, and the brightness of the picture of the display device is ensured.
Second embodiment: as shown in fig. 2, fig. 2 is a shunt circuit of a display device provided in the present application, and a main current submodule includes: scan voltage input terminal 101 (V Scan ) The scan voltage input terminal is connected to a preset first control voltage input terminal 102 (V in(n) ， n＝1,,…… ) The first MOS transistor 103 includes a first connection port, a second connection port, and a third connection port, where the first connection port is connected to the scan voltage input terminal 101, and the second connection port is connected to the first control voltage input terminal 102.
The embodiment provides an internal structure of a main current sub-module, which can adjust the input scanning voltage by adding a control voltage on the scanning voltage input end and then passing through an MOS tube.
Third embodiment: as shown in fig. 3, fig. 3 is a shunt circuit of a display device provided in the present application, and a shunt submodule includes:
the second control voltage input end 202, the second control voltage input end 202 is connected with the scan voltage input end 101 through the second MOS tube 203, the second MOS tube 203 includes a fourth connection port, a fifth connection port and a sixth connection port, wherein the fourth connection port is connected with the scan voltage input end 101, the fifth connection port is connected with the second control voltage input end 202, and the sixth connection port is connected with the third connection port to form a voltage output end of the target scan voltage output module.
According to the above embodiment, since the scan voltage is only input as the main current, there may be a problem that the potential becomes high due to the excessive instantaneous current, and here, by adding an additional control voltage and another MOS transistor, the additional control voltage is connected in series with the MOS transistor, and the MOS transistor and the additional control voltage connected in series are connected in parallel with the main current sub-module in the above embodiment, so as to achieve the purpose of splitting the voltage in the main current. When the instantaneous current increases, the problem of overlarge potential of the input end of the scanning voltage can be avoided through the action of shunt.
Fourth embodiment: as shown in fig. 4, fig. 4 is a shunt circuit of a display device provided in the present application, where the shunt sub-module further includes: the shunt resistor 204 is disposed between the fourth connection port and the scan voltage input terminal 101.
According to the above embodiment, when the additional control voltage and the second MOS transistor are added, the original main current path may be split, and before the splitting resistor is not added, the MOS transistor on the split current path may be powered, and when the splitting operation is performed, the voltage may be changed instantaneously, so that the voltage is increased suddenly to damage the MOS transistor on the split current path. Therefore, the shunt resistor can effectively avoid the problem that the MOS on the shunt line is damaged due to the increase of the instantaneous voltage.
In addition, after the shunt resistor is connected to the shunt route, the shunt module and the main current module are in a parallel connection state, so that the overall load impedance cannot change too much, the change of potential can be better controlled, and the fineness of potential control is improved.
Fifth embodiment: as shown in fig. 5, fig. 5 is a shunt circuit of the display device provided in the present application, where the shunt circuit further includes: the data voltage input terminal 30 is connected to the target scan voltage output module through a light emitting diode.
According to the embodiment, the internal structures of the main current sub-module and the shunt sub-module can be obtained, and the main current sub-module and the shunt sub-module form the target scanning voltage output module. Therefore, as shown in fig. 5, after the third interface of the first MOS transistor 103 and the sixth interface of the second MOS transistor 203 are connected, a final voltage output end of the target scan voltage output module can be obtained, and the voltage output end is a voltage output end with the potential split, and after the voltage output end is connected in series with the data voltage input end 30 and the light emitting diode, the brightness of the light emitting diode can be controlled, so as to avoid the light emitting diode with dark brightness.
Sixth embodiment: as shown in fig. 6, fig. 6 is a shunt circuit of the display device provided in the present application, wherein the shunt circuit includes at least one scan voltage output module, and includes: each scanning voltage output module in the at least one scanning voltage output module comprises target scanning voltage output modules, each scanning voltage output module is not connected with each other, each scanning voltage output module is respectively connected with a preset data voltage input end in series through a plurality of light emitting diodes, and one light emitting diode corresponds to one scanning voltage output module. The embodiment provides a longitudinal circuit arrangement structure in a control display device, which can avoid the condition that a longitudinal light emitting diode has darker brightness.
Seventh embodiment: as shown in fig. 7, fig. 7 is a shunt circuit of the display device provided in the present application, where the shunt circuit further includes: the data voltage input ends are not connected with each other, any one of the data voltage input ends is respectively connected with each scanning voltage output module in series through a plurality of light emitting diodes, and one light emitting diode corresponds to one scanning voltage output module.
The embodiment provides a connection mode of a plurality of target scan voltage output modules and a plurality of data voltage input ends in a display panel, which can prevent the light emitting diodes in each column and each row from being darker in the display device.
Eighth embodiment: as shown in fig. 8, fig. 8 is a shunt circuit of the display device provided by the application, which is characterized in that the shunt circuit includes at least one scan voltage output module, a part of scan voltage output modules in the at least one scan voltage output module includes target scan voltage output modules, the part of scan voltage output modules are not connected with each other, the part of scan voltage output modules are respectively connected with a preset data voltage input end in series through a plurality of light emitting diodes, and one light emitting diode corresponds to one scan voltage output module.
The difference between the target scan voltage output module provided in the embodiment of the present application and the above embodiment is that, when a plurality of scan voltage output modules are present in the display device, only some of the plurality of scan voltage output modules are the target scan voltage output modules mentioned in the embodiment of the present application. The purpose of this is to reduce the manufacturing cost of the display device if the other scan voltage output modules of the plurality of scan voltage output modules are common modules.
For example: as shown in fig. 8, the scan voltage output module at the lowest position of the display device may be set as a normal scan voltage output module in one display panel, which may cause only a problem that the brightness of the lowest display area in the display device is darker. Because the user is in use of the display device most of the time, the user's line of sight is generally focused on the central region of the picture, and therefore, when a region with darker brightness appears below the display device, the user is difficult to find, the visual experience of the user is not destroyed, the brightness of most regions of the display device is ensured, and meanwhile, the manufacturing cost can be reduced to a certain extent. It should be noted that this arrangement is only one longitudinal arrangement in the display device.
Ninth embodiment: as shown in fig. 9, fig. 9 is a shunt circuit of the display device provided in the present application, and is characterized in that the shunt circuit further includes:
the data voltage input ends are not connected with each other, any one of the data voltage input ends is respectively connected with each scanning voltage output module in at least one scanning voltage output module in series through a plurality of light emitting diodes, and one light emitting diode corresponds to one scanning voltage output module.
As the purposes of the above embodiments are the same, the present embodiment provides an arrangement manner in which only part of the scan voltage output modules in the plurality of scan voltage output modules are target scan voltage output modules, and by using the arrangement manner, the light emitting diodes in the display device can be arranged, so as to achieve the same technical effects as those in the above embodiments.
In addition, the embodiment of the application also provides a display device, which can be provided with the shunt circuit of the display device described in any one of the embodiments.
In the foregoing embodiments, the descriptions of the embodiments are focused on, and the portions of one embodiment that are not described in detail in the foregoing embodiments may be referred to in the foregoing detailed description of other embodiments, which are not described herein again.
The foregoing describes in detail the shunt circuit of a display device provided in the embodiments of the present application, and specific examples are applied herein to illustrate the principles and embodiments of the present application, where the foregoing examples are only used to help understand the method and core ideas of the present application; meanwhile, as those skilled in the art will vary in the specific embodiments and application scope according to the ideas of the present application, the contents of the present specification should not be construed as limiting the present application in summary.
