Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The display panel and the display device including the display panel according to the embodiments of the present invention may be a display having only a display function, or may be an intelligent terminal device capable of providing an operation interaction function.
The invention provides a split-screen scanning module, which comprises: the scanning unit comprises a first scanning unit group, a second scanning unit group, a switch group, a first signal circuit group and a second signal circuit group.
The signals provided by the first signal circuit group are respectively connected into the first scanning unit group and the second scanning unit group, and the signals provided by the second signal circuit group are connected into the second scanning unit group; the switch group is arranged between the first scanning unit group and the second scanning unit group;
when the switch group is switched on, the first scanning unit group and the second scanning unit group both respond to the signals provided by the first signal circuit group to carry out progressive scanning; when the switch group is turned off, the first scanning unit group performs progressive scanning in response to signals provided by the first signal circuit group, and the second scanning unit group performs progressive scanning in response to signals provided by the second signal circuit group.
Specifically, unlike the full-screen scanning method in the prior art, in the present embodiment, each scanning sub-unit can be divided according to the split-screen requirement of the display panel, and each scanning sub-unit can be divided into the first scanning unit group and the second scanning unit group according to the position of each sub-scanning unit on the display panel. The number of the first scanning unit group and the second scanning unit group can be multiple, and the first scanning unit group and the second scanning unit group can be distributed on the display panel in a cross arrangement mode; in addition, the number of groups of the first and second scanning unit groups may be one, that is, divided in the upper half screen and the lower half screen of the display panel.
Correspondingly, in order to realize the split-screen scanning, two different signal circuit groups, namely a first signal circuit group and a second signal circuit group, are also arranged in the split-screen scanning module. Meanwhile, a switch group is further arranged between the first scanning unit group and the second scanning unit group, and when the switch group is switched on, the first scanning unit group and the second scanning unit group can simultaneously scan step by step according to signals provided by the first signal circuit group through control over the switch group, that is, under the condition that the switch group is switched on, the first scanning unit group and the second scanning unit group share the signals provided by the first signal circuit group, and full-screen-based scanning is realized.
When the switch group is closed, the first scanning unit group still scans step by step according to the signals provided by the first signal circuit group, the second scanning unit group is relatively disconnected with the first signal circuit group, and the scanning is performed step by step based on the signals provided by the second signal circuit group so as to realize the split-screen scanning.
That is to say, through adopting above-mentioned module structure, can make the first scanning unit group of split screen scanning module carry out full-screen scanning strategy when the switch block switches on, and carry out split screen scanning strategy when the switch block is closed, and then can provide different scanning refresh frequencies for the different regions of display panel, make display panel not receive under MIPI's maximum transmission rate's restriction, improve display panel's scanning signal frequency, in order to improve its refresh frequency when the display data.
It should be noted that, the first signal circuit group and the second signal circuit group mentioned above may both carry signals of multiple control types including a trigger signal, a clock signal, and the like, and correspondingly, for signals of different control types, different switches are also correspondingly arranged in the switch group, so that the split-screen scanning module may respond to signals provided by the same or different signal circuit groups under the control of each switch of the switch group.
To further describe the split-screen scanning module according to the first embodiment of the present invention, fig. 1 is a schematic circuit structure diagram of the split-screen scanning module according to the first embodiment of the present invention.
Based on the different requirements of the split-screen, the first scanning unit group in the screen scanning module may be specifically composed of a scanning subunit 1 and a scanning subunit 2 … …, which are connected in a stepwise manner, and the second scanning unit group is composed of a scanning subunit b +1 and a scanning subunit b +2 … …, which are connected in a stepwise manner, and a scanning subunit b 2 a. Wherein a and b may be equal or different.
For convenience of description, the following description will be given by taking a and b as examples, that is, as shown in fig. 1,
in the split-screen scanning module, a first scanning unit group consists of a scanning subunit 1 and a scanning subunit 2 … … which are connected step by step; the second scanning unit group is composed of a scanning sub-unit a +1 and a scanning sub-unit a +2 … …, which are connected in a cascade manner, and a scanning sub-unit 2 a.
Each of the scan sub-units includes at least a first signal output terminal OUT and a first signal input terminal IN. The split-screen scanning module further comprises a first control signal circuit INa for providing a first trigger signal, and a second control signal circuit INb for providing a second trigger signal. The first control signal circuit INa is connected to the first signal input terminal IN of the scan subunit 1, and the second control signal circuit INb is connected to the first signal input terminal IN of the scan subunit a + 1.
The first signal output end OUT and the first signal input end IN of the scanning subunit 2a of the scanning subunit 1 and the scanning subunit 2 … … are sequentially connected step by step, and meanwhile, a first switch M3 is further disposed between the first signal output end OUT of the last scanning subunit a of the first scanning unit and the first signal input end IN of the first scanning subunit a +1 of the second scanning unit.
When the first switch M3 is turned on, the display panel executes a full-screen scanning strategy, and at this time, all the scanning units will be sequentially triggered under the action of the first trigger signal provided by the first control signal circuit INa, that is, when the first trigger signal is transmitted to the first signal input terminal IN of the scanning subunit 1, the scanning subunit 1 is triggered and outputs a trigger signal which can be used for triggering the scanning subunit 2 to the first signal input terminal IN of the scanning subunit 2 through the first signal output terminal OUT of the scanning subunit 1, that is, the trigger signal will be sequentially transmitted along the trigger signal input and output terminals of the scanning subunits connected IN a stage-by-stage manner, so that each scanning subunit is sequentially triggered to execute scanning.
When the first switch M3 is turned off, the display panel executes the split-screen scanning strategy, and at this time, only the scanning sub-units 1 to a in the first scanning unit will be sequentially triggered based on the first trigger signal provided by the first control signal circuit INa, and the triggering manner is the same as the aforementioned manner. After the scan subunit a completes triggering, the first trigger signal cannot be transmitted to the scan subunit a +1 due to the turn-off of the first switch M3. At this time, the second control signal circuit INb provides a second trigger signal to the scan subunit a +1, so that the scan subunits a +1 to 2a can be triggered to perform scanning based on the second trigger signal.
By adopting the triggering mode, the scanning subunit executes triggering based on different triggering frequencies according to different triggering signals, and further provides a basis for split-screen scanning.
In addition, in the split-screen scanning module, each scanning subunit further includes a second signal input terminal, as shown in fig. 1, in the present schematic diagram, each scanning subunit includes second signal input terminals CK1 and CK2, in other examples, the number and the type of the second signal input terminals are changed according to the difference of the structure and the implemented function of the scanning subunit itself, that is, the embodiment only takes two second signal input terminals as an example for illustration, but the number and the type are not limited.
This embodiment will be described by taking as an example that the second signal input terminal is used for receiving a clock signal, and the third control signal circuit and the fourth control signal circuit are used for providing the clock signal:
in order to cooperate with the second signal input terminals CK1 and CK2 in the scanning sub-unit, the split-screen scanning module further includes third control signal circuits CK1a and CK2a for providing the first clock signal, and fourth control signal circuits CK1b and CK2b for providing the second clock signal. As described above, the clock signal lines CK1a, CK2a, CK1b, and CK2b described above are all exemplary.
In the structure shown in FIG. 1, the second signal input terminals CK1 and CK2 of the scanning sub-units 1 to 2a are alternately connected to the third control signal circuits CK1a and CK2a, respectively; the second signal input terminals CK1 and CK2 of the scan sub-units a +1 through 2a are also alternately connected to fourth control signal circuits CK1b and CK2b, respectively. Meanwhile, the second signal input terminals CK1 and CK2 of the last-stage scanning sub-unit a of the first scanning unit group are also connected to one ends of the second switches M1 and M2, respectively, and the second signal input terminals CK1 and CK2 of the first-stage scanning sub-unit a +1 of the second scanning unit group are connected to the other ends of the second switches M1 and M2, respectively.
With such a structure, it is possible to cause each of the scanning sub-units 1 to 2a to perform scanning by the first clock signals CK1a and CK2a when the second switches M1 and M2 are turned on. When the second switches M1 and M2 are turned off, the scan sub-unit 1 to the scan sub-unit a perform scanning under the action of the first clock signals CK1a and CK2a, and the scan sub-unit a +1 to the scan sub-unit 2a perform scanning under the action of the second clock signals CK1b and CK2 b.
By adopting the clock signal scanning mode, the scanning subunit executes scanning based on different clock frequencies according to different clock signals, and further provides a basis for split-screen scanning.
Optionally, the split-screen scanning module further comprises: and the fifth control signal circuit is electrically connected with the control ends of the first switch and the second switch. The fifth control signal circuit can be specifically a driving chip, that is, the control ends of the switches are connected, and the control ends of the switches are connected to the SET end of the driving chip, so that the switches can receive the control of the driving chip, and further, the switches in the switch group can be synchronously controlled, and the synchronism is ensured.
In the split-screen scanning module provided by the first embodiment of the present invention, the split-screen scanning module, the control method thereof, the display panel and the display device provided by the present invention are arranged in the split-screen scanning module, and the first scanning unit group, the second scanning unit group, the first switch, the first control signal circuit and the second control signal circuit are arranged in the split-screen scanning module; when the first switch is conducted, the first scanning unit group and the second scanning unit group respond to the signal provided by the first control signal circuit to carry out progressive scanning; when the first switch is turned off, the first scanning unit group scans step by step in response to a signal provided by the first control signal circuit, and the second scanning unit group scans step by step in response to a signal provided by the second control signal circuit, so that the split-screen scanning module board provided by the invention can provide different scanning refresh frequencies for different areas of the display panel, and further improve the scanning signal frequency of the display panel without being limited by the maximum transmission rate of MIPI (mobile industry processor interface), so as to improve the refresh frequency of the display panel when the display panel displays data.
On the basis of the split-screen scanning module provided in the first embodiment, fig. 2 is a signal schematic diagram of a control method of the split-screen scanning module provided in the second embodiment of the present invention.
In the second embodiment, the control method is used for controlling the split-screen scanning module shown in fig. 1, and includes:
in a first mode, controlling a first switch and a second switch to be conducted so that the first scanning unit group and the second scanning unit group perform progressive scanning in response to control signals of a first signal frequency respectively provided by the first control signal circuit and a third control signal circuit;
in a second mode, the first switch and the second switch are controlled to be turned off, so that the first scanning unit group performs progressive scanning in response to control signals of first signal frequencies provided by the first control signal circuit and the third control signal circuit respectively, and the second scanning unit group performs progressive scanning in response to control signals of second signal frequencies provided by the second control signal circuit and the fourth control signal circuit.
It should be noted that the first mode may refer to a full-screen scanning mode, and the second mode may refer to a split-screen scanning mode.
Specifically, fig. 2 is a schematic signal diagram of a display panel when a split-screen refresh of the display panel is completed. Fig. 2 is a schematic signal diagram of a split-screen scanning strategy, in which a SET terminal in the diagram is SET high to turn off each switch in a switch group, a lower half screen in the diagram corresponds to the first scanning unit group, and an upper half screen corresponds to the second scanning unit group. The scanning sub-units 1 to a in the first scanning unit group scan one by one, the scanning time length is T, then the scanning sub-units a +1 to 2a in the second scanning unit group continuously complete two times of scanning, and the scanning time length is T/2 each time, so that high-frequency scanning is realized, and the refresh frequency is improved. In the signal diagram, in order to ensure synchronization of the signals, the signal frequencies of the signals provided by the same control signal circuit should be kept consistent.
Optionally, when the first switch and the second switch are turned on, the second control signal circuit and the fourth control signal circuit provide no signal. That is to say, through the control of the second control signal circuit and the fourth control signal circuit, the split screen refreshing is realized by matching with the split screen strategy, and the electric power consumption of the display panel under the high refresh rate is further reduced.
Optionally, the first signal frequency is different from the second signal frequency, wherein the first signal frequency is half of the second signal frequency.
When the signal frequency is adopted, when the first switch and the second switch are conducted, the display panel refreshes by adopting the first signal frequency, namely, full-screen refreshing is carried out by adopting a relatively lower signal frequency; when the first switch and the second switch are turned off, the display area corresponding to the first scanning unit group of the display panel is refreshed by adopting the first signal frequency, and the display area corresponding to the second scanning unit group of the display panel is refreshed by adopting the second signal frequency, namely, the first scanning unit adopts the relatively lower signal frequency for brushing, and the second scanning unit adopts the relatively higher signal frequency for refreshing, so that the high-frequency refreshing of the split screen is realized.
Further, after the first scanning cell group completes one progressive scanning in response to the signals supplied from the first and third control signal circuits while the first and second switches are turned off, the second scanning cell group completes two progressive scanning in response to the signals supplied from the second and fourth control signal circuits.
The invention provides a control method of a split-screen scanning module, which comprises the steps that a first scanning unit group, a second scanning unit group, a first switch, a first control signal circuit and a second control signal circuit are arranged in the split-screen scanning module; when the first switch is conducted, the first scanning unit group and the second scanning unit group respond to the signal provided by the first control signal circuit to carry out progressive scanning; when the first switch is turned off, the first scanning unit group scans step by step in response to a signal provided by the first control signal circuit, and the second scanning unit group scans step by step in response to a signal provided by the second control signal circuit, so that the split-screen scanning module board provided by the invention can provide different scanning refresh frequencies for different areas of the display panel, and further improve the scanning signal frequency of the display panel without being limited by the maximum transmission rate of MIPI (mobile industry processor interface), so as to improve the refresh frequency of the display panel when the display panel displays data.

Similar to the circuit structure and the corresponding control manner, a switch group needs to be arranged between any two adjacent scanning unit groups. By controlling the switch group, when the switch group is conducted, each group of scanning unit groups can simultaneously execute progressive scanning according to signals provided by the same group of signal circuit groups in the plurality of groups of signal circuit groups; when the switch group is turned off, each group of scanning unit groups respectively executes progressive scanning according to different signals in different groups of signal circuit groups.
As an alternative embodiment, the number of the multiple scanning unit groups may be equal to or greater than the number of the multiple signal circuit groups, so that when the switch group is turned off, each scanning unit group performs progressive scanning according to the signals provided by the signal circuit group connected to the scanning unit group, that is, performs split-screen scanning with different frequencies according to different split-screen strategies.
