FIG. 1 is a schematic flowchart of a method for adjusting a display capability provided by an embodiment of the present invention. The method can be as follows.

Step 101: Obtain the display driving capability of the control device.

Wherein, the display driving capability is used to characterize the capability of driving the display system to display.

In step 101, when the device is powered on, or when a set trigger event is met, the display driving capability of the control device is obtained.

For example: an integrated terminal with both a control device and a display system, when the terminal is powered on and started, obtains the display driving capability of the control device.

Specifically, ways to obtain the display driving capability of the control device include but are not limited to the following ways:

The first way:

Read the system configuration information of the control device, and obtain the display driving capability from the system configuration information.

The second way:

Read the memory information of the control device, and obtain the display driving capability of the control device according to the memory information.

Step 102: According to the corresponding relationship between the configured display driving capability and the theoretical display capability and the acquired display driving capability, obtain the theoretical display capability corresponding to the display driving capability.

In step 102, the configuration file is read, and the corresponding relationship between the display driving capability contained in the configuration file and the theoretical display capability is obtained; the display driving capability is obtained according to the corresponding relationship and the acquired display driving capability Corresponding theory shows ability.

The system configuration information of the control device includes the corresponding relationship between the display driving capability and the theoretical display capability, so that when the control device obtains the system configuration information, the corresponding relationship between the display driving capability and the theoretical display capability is obtained.

For example, assuming that the display driving capability is represented by the memory size, the corresponding relationship between the memory size value and the display resolution may be pre-configured.

As shown in Table 1, it is a schematic diagram of the corresponding relationship between the pre-configured memory size value and the display resolution:

Table 1

system memory display resolution

512M 720P 1G 1080P 2G 4K

It can be seen from Table 1 that with the different display driving capabilities (for example: memory size) configured by the control device, the display resolutions supported by the display system controlled by the control device are also different. For example: the stronger the display driving capability, the larger the value of the display resolution; on the contrary, the weaker the display driving capability, the smaller the value of the display resolution.

Step 103: Obtain the actual display capability of the display system controlled by the control device.

In step 103, ways to obtain the actual display capabilities of the display system controlled by the control device include but are not limited to the following ways:

The first way:

Read the device information of the timing controller (English: Timer Control; abbreviation: TCON), and analyze and obtain the actual display capability of the display system controlled by the control device from the device information.

Wherein, the actual display capability includes the actual display resolution supported by the display system.

For example: assume that the actual display capability (for example: display resolution) of the display system controlled by the control device determined in step 103 is 1080P, and the theoretical display capability (for example: display resolution) of the display system that can be driven by the control device obtained in step 102 resolution) is 720P, it can be seen that the theoretical display resolution is smaller than the actual display resolution, then automatically adjust the display resolution of the display system to 720P at this time.

Assume that the actual display capability (for example: display resolution) of the display system controlled by the control device determined in step 103 is 1080P, and the theoretical display capability (for example: display resolution) of the display system that can be driven by the control device obtained in step 102 ) is 4K, it can be seen that the theoretical display resolution is not less than the actual display resolution, then the display resolution of the display system is still 1080P at this time.

It should be noted that the adjustment of the display capability in the embodiment of the present invention is not limited to the adjustment of the display capability of the display system, and may also adjust the display capability of windows displayed in the display system.

When adjusting the display capability of the window displayed in the display screen of the display system, the above-mentioned step 103 obtains the actual display capability of the display window, and then step 104 adjusts the obtained display window according to the theoretical display capability obtained in step 102. The actual display capability, the adjustment method is the same as the above adjustment method, and will not be repeated here.

For example: when the system is started and a new application is started, the display resolution of the display window of the application is adjusted in the manner of the embodiment of the present invention. Assume that the display resolution supported by the application display window is 1080P, and the theoretical display resolution corresponding to the acquired system memory is 4k. Since the theoretical display resolution is greater than the actual display resolution, then configure the display resolution of the application display window to be 1080P; Assume that the display resolution supported by the application display window is 4K, and the theoretical display resolution corresponding to the acquired system memory is 1080P. Since the theoretical display resolution is smaller than the actual display resolution, configure the display resolution of the application display window to be 1080P.

Through the solution of the embodiment of the present invention, the display driving capability of the control device is obtained, and the display driving capability is used to characterize the capability of driving the display system for display; according to the corresponding relationship between the configured display driving capability and the theoretical display capability and the acquired The display driving capability is obtained by obtaining a theoretical display capability corresponding to the display driving capability; obtaining the actual display capability of the display system controlled by the control device; adjusting the acquired actual display capability according to the theoretical display capability, and setting The adjusted actual display capability is allocated to the display system. In this way, when the display driving capability of the control device is obtained, the theoretical display capability of the display system that can be driven by the control device can be obtained, and the actual display capability of the display system controlled by the control device can be adjusted by using the obtained theoretical display capability. Effectively realize the automatic matching of the display capability of the display system according to the display driving capability of the control device, simplify the complexity of the adaptation operation between the control device and the display system, and achieve intelligent adaptation between the control device and the display system.

Step 202: According to the corresponding relationship between the configured memory size and the supported theoretical display resolution, determine the theoretical display resolution corresponding to the obtained memory size.

In step 202, read the system configuration information, obtain the corresponding relationship between the configured memory size and the supported theoretical display resolution from the system configuration information, and traverse the corresponding relationship to obtain the theoretical display resolution corresponding to the obtained memory size Rate.

Alternatively, if the correspondence between the memory size and the supported theoretical display resolution is stored in the database, the theoretical display resolution corresponding to the memory size can be obtained by querying the database.
