[0070] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present application are proposed.

[0071] Embodiment one

[0072] Figure 3 is a flowchart of the first embodiment of the under-screen light sensing light leakage test method of the present application. An under-screen light sensing light leakage test method, the method comprises:

[0073] S1, before the screen enters the bright screen display, the first ambient light data collected under the screen when the screen is off is taken as the initial value of the ambient brightness.

[0074] S2, determine the screen brightness parameter corresponding to the initial value of the ambient brightness, and collect the second ambient light data of the first frame of display under the screen when the screen enters the bright screen display according to the screen brightness parameter.

[0075] S3, according to the difference between the second ambient light data and the first ambient light data, the light leakage compensation value is obtained, and the third ambient light data of each frame of display under the screen is collected when each frame is refreshed, and the size relationship between the difference between the third ambient light data and the first ambient light data and the preset threshold value is judged.

[0076] S4, if the difference between the third ambient light data and the first ambient light data is greater than the preset threshold value, black frame insertion is performed, and the fourth ambient light data collected under the screen when the black frame is inserted is updated as the initial value of the ambient brightness, if the difference between the third ambient light data and the first ambient light data is less than or equal to the preset threshold value, the difference between the fifth ambient light data collected under the screen when the current frame of display and the light leakage compensation value is taken as the current value of the ambient brightness.

[0077] In the embodiment, the mobile terminal such as a mobile phone is taken as an example for illustration. When the mobile terminal is about to enter normal screen display, the mobile terminal ambient light monitoring and collecting module controls the under-screen ambient light sensor to start working. The under-screen ambient light sensor collects ambient light data Als_balck when the screen is off. The mobile terminal ambient light monitoring and collecting module takes the ambient light data Als_balck as the initial value Als_start of the ambient brightness this time, and then sends the screen brightness parameter instruction matched with the current ambient brightness to the mobile terminal screen management module. The mobile terminal screen management module extracts the screen brightness parameter information in the received screen brightness parameter instruction. The mobile terminal screen management module controls the screen to display the content of the frame normally according to the brightness level matched with the screen brightness parameter information in the screen brightness parameter instruction.

[0078] In the embodiment, when the mobile terminal is in screen display, the mobile terminal ambient light monitoring and collecting module controls the under-screen ambient light sensor to collect the first frame of ambient light data Als_frame0 again. After the under-screen ambient light sensor completes data collection, the mobile terminal ambient light monitoring and collecting module calculates the leakage compensation value Als_diff = Als_te0 - Als_black by comparing the ambient light data Als_balck when the screen is off with the first frame of ambient light data Als_te0 when the screen is on. Then, the mobile terminal ambient light monitoring and collecting module controls the under-screen ambient light sensor to collect the ambient light data Als_framen of each frame of screen refresh, and the ambient light monitoring and collecting module compares the ambient light data Als_framen of the frame when the screen is on with the ambient light data Als_balck when the screen is off.

[0079] In the embodiment, if the difference between the ambient light data Als_framen under the screen in this time and the ambient light data Als_balck when the screen is off in this time is greater than the preset threshold Als_diff_type, the ambient light monitoring and collecting module sends a black frame insertion instruction to the screen management module. After the ambient light monitoring and collecting module sends the black frame insertion instruction to the screen management module, the ambient light monitoring and collecting module monitors the tearing effect (synchronization signal) and becomes high level or monitors that the mobile terminal display enters a short black frame mode, the mobile terminal ambient light monitoring and collecting module controls the under-screen ambient light sensor to start working, the under-screen ambient light sensor collects the ambient light data Als_balck when the screen is off, the mobile terminal ambient light monitoring and collecting module takes the ambient light data Als_balck as the initial value Als_start of the ambient brightness in this time, and then the mobile terminal ambient light monitoring and collecting module sends a screen brightness parameter instruction matched with the current ambient brightness to the mobile terminal screen management module, and the mobile terminal screen management unit controls the screen to set a brightness level matched with the screen brightness parameter and normally display the frame picture content.

[0080] In the embodiment, if the difference between the ambient light data Als_framen under the screen in this time and the ambient light data Als_balck when the screen is off in this time is less than or equal to the preset threshold Als_diff_type, the mobile terminal ambient light monitoring and collecting module calculates the difference between the under-screen ambient light sensor compensation value Als_diff and the ambient light data Als_framen under the screen in this time, Als_framen=Als_framen-Als_diff, the mobile terminal ambient light monitoring and collecting module takes the calculated Als_framen in this time as the current ambient brightness value, and then the mobile terminal ambient light monitoring and collecting module sends a screen brightness parameter instruction matched with the current ambient brightness to the mobile terminal screen management unit, and the mobile terminal screen management unit controls the screen to set a brightness level matched with the screen brightness parameter and normally display the frame picture content.

[0081] It can be seen that, in the embodiment, first, the black frame environment brightness value Als_balck is acquired before the first frame of picture is displayed, the light leakage compensation value is calculated according to Als_balck, the environment brightness value Als_framen is collected every time the screen is displayed in the lighted state, and the environment light data Als_framen under the current frame in the lighted state is compared with the environment light data Als_balck in the unlighted state, and when the difference between the two is greater than a preset threshold Als_diff_type, a black frame insertion instruction is sent to the screen management module. When the screen TE signal becomes a high level or it is monitored that the mobile terminal display enters a short black frame mode, the environment light sensor under the screen re-collects the environment light data Als_balck in the unlighted state, and a new screen light leakage value is calculated according to the current black screen environment brightness value Als_balck. Thus, the light leakage compensation value is refreshed in real time according to the lighted state environment brightness value, the collection accuracy is improved, and the user experience is improved.

[0082] The embodiment has the beneficial effects that, by taking the first environment light data collected under the screen in the unlighted state of the screen as an environment brightness initial value before the screen enters the lighted state display, a screen brightness parameter corresponding to the environment brightness initial value is determined, and the second environment light data under the screen in the first frame of display is collected when the screen enters the lighted state display according to the screen brightness parameter, the light leakage compensation value is obtained according to the difference between the second environment light data and the first environment light data, the third environment light data under the screen in every frame of display is collected every time the frame is refreshed, and the size relationship between the difference between the third environment light data and the first environment light data and a preset threshold is judged, if the difference between the third environment light data and the first environment light data is greater than the preset threshold, black frame insertion is performed, and the fourth environment light data collected under the screen in the black frame insertion is updated as the environment brightness initial value, and if the difference between the third environment light data and the first environment light data is less than or equal to the preset threshold, the difference between the fifth environment light data collected under the screen in the current frame of display and the light leakage compensation value is taken as the current environment brightness value.
