The four spliced sub-screens positioned in each sub-screen group are aligned up and down, and the 12 spliced sub-screens are spliced to form a rectangular display area.
With reference to fig. 1, each sub-panel group includes 2 driving units, each 2 tiled sub-panels share 1 driving unit, each driving unit supplies power independently, and 2 driving units belonging to the same sub-panel group share the same sub-control unit. In the whole structure of the display device, the 3 sub-control units CU1-CU3 coordinate the 6 driving units DU1-DU6 to complete the function, and the integrated Power Management circuit (Power Management IC, PMIC for short) centrally manages the Power supply of the 6 channels DU1-DU 6. The control unit uniformly manages 3 sub-control units CU1-CU3 in a bus-like manner so as to realize the operations of distributing and coordinating resources, sending instructions, reading and writing data and the like.
The drive unit is a panel drive chip capable of driving the spliced sub-screens to display at a certain refresh rate, in this embodiment, 1 drive unit corresponds to 2 spliced sub-screens, that is, every 2 spliced sub-screens correspond to the same refresh rate. The 12 tiled sub-screens can set 6 refresh rates.
The drive unit can control the corresponding spliced sub-screen display according to the stored fixed refresh rate, the fixed refresh rate is stored in a register of the drive unit when the display device leaves a factory, the fixed refresh rate is kept unchanged in the subsequent working process, and the drive unit can receive and control the display of a data source at the fixed refresh rate for a long time.
In a possible implementation mode, the refresh rate of the driving unit can be changed under a certain condition, the condition for changing the refresh rate can be that the enable, the key or/and the upstream control device change the control signal parameter of the driving unit, when the modification condition is met, the refresh rate of the driving unit is rewritten, and the driving unit works at a new refresh rate after the refresh rate is changed.

The display area of the first sub-screen group 101 is defined as a first display area, the display area of the second sub-screen group 102 is defined as a second display area, the display area of the third sub-screen group 103 is defined as a third display area, the refresh rate of the first display area under the control of the driving unit is a first refresh rate, the refresh rate of the second display area under the control of the driving unit is a second refresh rate, and the refresh rate of the third display area under the control of the driving unit is a third refresh rate.
In the foregoing embodiment, the display area is displayed at a specific refresh rate under the control of the driving unit, but the embodiment of the present application is not limited thereto, and the refresh rate may be a property of the display area itself, and may also be implemented by an upstream control device, such as a Graphics Processing Unit (GPU), so that different display areas can be displayed at different refresh rates without a driving unit.
The display area of the display device comprises three display areas, namely a first display area, a second display area and a third display area, wherein the first display area, the second display area and the third display area are sequentially arranged from top to bottom in the height direction, the second display area in the middle is a core attention area when a user uses the display device, and the first display area and the third display area on the upper side and the lower side of the second display area are non-core attention areas when the user uses the display device. That is to say, in the display device display process, the attention and the focus of the user are concentrated in the second display area located in the middle, so the second refresh rate is set to be higher than the first refresh rate and higher than the third refresh rate in this embodiment, that is, the refresh rate of the core attention area of the user is increased, thereby the display effect is improved, the viewing experience of the user is ensured, and simultaneously, the refresh rate of the non-core attention area is displayed at a refresh rate lower than the core attention area, even lower than the conventional refresh rate, the overall power consumption of the display device is reduced, and the display effect and the power consumption are flexibly balanced.
In a specific example, the refresh rate of sub-screens 5-8 in the core region of interest is set to 120Hz, the refresh rate of sub-screens 1-4 in the non-core region of interest, and sub-screens 9-12 is set to 60 Hz.
Further, more refresh rate gradients may be provided to more flexibly balance display effects and power consumption, for example, in one embodiment, the refresh rate of the first display region is set to 120Hz, the refresh rate of the second display region is set to 90Hz, and the refresh rate of the third display region is set to 60 Hz.
In this embodiment, three display regions are taken as an example for description, but the embodiment of the present application is not limited thereto, and the display device includes at least two display regions, and the refresh rates of at least two display regions in all the display regions are different. Preferably, the display device comprises more than three display areas, the division of the display areas is finer due to the larger number of the display areas, and the control is more flexible and diversified by matching with more and finer refresh rate gradients.
It is further preferable that the refresh rates of the different display areas meet a frequency that the different display areas can be synchronized within a period of a preset time, that is, the different refresh rates overlap again after the preset time. For example, the combination of 120Hz, 90Hz and 60Hz, and for example, the combination of 120Hz and 60Hz, so the design can avoid the different display areas from being obvious in sense, and further improve the display effect of the display device.
In addition, in this embodiment, the different display regions are sequentially arranged from top to bottom, but the embodiment of the present application is not limited to this, for example, the different display regions may be arranged horizontally, or may be annular/square display regions sleeved inside and outside, or may be arranged in any form, and all the display regions may form a display region of the display device.
In this embodiment, the high refresh rate display area and the low refresh rate display area are divided by the core attention area and the non-core attention area, but the embodiment of the present application is not limited thereto, and in a possible implementation manner, the display device may divide the high refresh rate display area and the low refresh rate display area according to different display contents, for example, the display area corresponding to the dynamic picture is set as the high refresh rate area, and the display area corresponding to the static picture is set as the low refresh rate display area. In such an embodiment, the correspondence between the display area and the refresh rate is not generally fixed, but is adjusted according to the display content, thereby requiring the driving unit to have a function of adjusting the refresh rate.
In this embodiment, display device adopts 12 concatenation sub-screens to splice and forms, and 12 concatenation sub-screens divide into 3 sub-screen groups, and every sub-screen group is including forming 4 concatenation sub-screens of a display area, still including 2 drive unit that control display area shows, but this application is not limited to this.
The number and the control relation of the first spliced sub-screen and the driving units can be determined according to actual conditions, and the following conditions are met: the number of the spliced sub-screens is at least two, the number of the driving units is at least two, each driving unit controls at least one spliced sub-screen to display, all the driving units are mutually independent, and the refresh rates of the display controlled by at least two driving units are unequal. For example, in one possible implementation, 2 tiled sub-panels and 2 driving units are included, one driving unit controls one tiled sub-panel to display, and the two driving units control the tiled sub-panel to display with unequal refresh rates.
Secondly, the shape and arrangement mode of the spliced sub-screens can be determined according to the actual application scene, for example, the sub-screens can be triangles, diamonds or regular polygons spliced into a plane display area, and can also be arcs spliced into an arc display area.
In addition, the display device can be a complete display panel, and the display area is a component of the display panel.
The embodiment of the present application also provides a display control method for the display device, as shown in fig. 3, the display method includes the following steps:
step S10: acquiring display data;
the display data is data that needs to be output and displayed and is received by a Graphics Processing Unit (GPU), and the display data may be still picture data or dynamic video data.
Step S20: distributing display content according to the display area;
according to the embodiment of the display device, the display device comprises at least two display areas which are combined to form the display area of the display device, and the refresh rates of at least two display areas in all the display areas are not equal. After the graphics processing unit GPU obtains the display data, the display data are divided into different display contents according to different display areas, and partition rendering is carried out. For example, in the above embodiment of 3 display regions, the display data is allocated into 3 display contents according to the 3 display regions.
Step S30: and outputting the display content at a frame rate corresponding to the display area refresh rate.
And after the distribution of the display content is finished, outputting a data source with a frame rate corresponding to the refresh rate of the display area to the display area, and receiving and controlling the display of the data source by the display area according to the set refresh rate.
Because the refresh rates of at least two display areas in all the display areas are not equal, the display refresh rates of different display contents after distribution are not equal.
When the frame rate of the display content is equal to the refresh rate of the display area, the display content can be directly output; when the frame rate of the display content is not equal to the refresh rate of the display area, the GPU may process the display content into a frame rate data source equal to the refresh rate of the display area by using a frame interpolation or frame extraction algorithm and output the frame rate data source. Therefore, the display data processed by the GPU can output at least two data sources with different frame rates.
By adopting the display control method, different display areas in the display area can be displayed by adopting different refresh rates, so that the relationship between the display effect and the power consumption is balanced, and the energy consumption is reduced on the basis of ensuring the display effect.
In general, the display area is controlled by the driving unit to display, and optionally, in one possible embodiment, the step S30 includes:
selecting a target refresh rate according to the display content;
and controlling the driving unit to adjust the target refresh rate, and outputting the display content at a frame rate corresponding to the target refresh rate of the display area.
In the embodiment that the driving unit supports real-time adjustment of the refresh rate, the driving unit adjusts the refresh rate of the driving unit in real time along with the display content and/or the display setting condition, thereby realizing real-time variable frequency display, realizing dynamic control of display, and more effectively and fully balancing the display effect and power consumption. For example, when there are many static images, the refresh rate of the driving unit can be adjusted to a lower value, and the GPU is controlled to output a data source with a lower frame rate; when the number of dynamic pictures is large, the refresh rate of the driving unit can be adjusted to a high value, and the GPU is controlled to output a data source with a high frame rate.
Optionally, in a possible implementation, the display control method further includes:
receiving a modification request for modifying the refresh rate of the drive unit;
modifying a refresh rate of the drive unit in response to the modification request;
the modification request is triggered by a change in an enable, key press, or/and control signal parameter.
In the implementation mode that the refresh rate of the driving unit is fixed and can be modified, the refresh rate of the driving unit can be modified under a certain condition, the condition for changing the refresh rate can be the change of parameters of an enable signal, a key or/and a control signal, when a modification request is received, the parameter corresponding to the driving unit is rewritten/initialized, and the driving unit works at a new refresh rate after the modification.
For example, the display device may set different operation modes, where the operation modes include a video mode, a document mode and a game mode, and in the different modes, the refresh rate of the driving unit is changed, for example, the refresh rate in the game mode is generally high, and the refresh rate in the document mode is generally low, and the user may select the operation mode by pressing a key, setting a display, etc. to operate the display device according to the operation mode.
