For different display types, the corresponding screen brightness adjustment schemes are also different. When the display is an LCD display, it has a backlight, so the brightness of the backlight corresponding to the focus area can be adjusted, that is, the brightness of the screen area is realized. Adjustment; when the display screen is an organic light-emitting diode display screen, it does not have a backlight source, and only needs to adjust the color of the pixels on the display panel corresponding to the focus area, such as adjusting to a dark color, which reduces the brightness of the focus area, Adjusting to a lighter color increases the brightness of the focus area.

Next, a screen backlight control method according to an embodiment of the present invention will be described in detail with reference to FIG. 4A and FIG. 4E .

In this embodiment, the screen backlight control method includes the following steps:

1. First use a table to record the brightness value of each backlight unit in the backlight panel.

2. The system maintains a default overall backlight brightness D, and the value can be set by the user; the brightness value of each backlight unit in the above table will be set to the default overall backlight brightness D.

For example, assuming that D=50, the initial display brightness of the terminal screen is as shown in FIG. 4A .

3. The application program can set a certain area as the focus area, the screen area corresponding to the focus area is high brightness, the brightness value is H, and H>D. Specific steps are as follows:

A. Set the brightness value of all backlight units (current brightness-D);

B. Set the brightness value of the area that needs high brightness (current brightness + H). This change process can be a direct jump or a gradual change.

C. Set a timer. After the timer is triggered, the brightness value of the high brightness area will be restored to (current brightness - H). This change process can be a direct jump or a gradual change.

For the above step A, as shown in Figure 4B, assuming that the current brightness value is D, set the brightness value of all backlight units to (D-D) = 0, then the entire terminal screen is a dark screen at this time (when the brightness value is 0, The actual screen has no brightness, for the convenience of understanding, the contents of the screen can still be seen in the picture).

For the above step B, as shown in Figure 4C, the area where the predetermined object "Contact" in the application interface is located is the focus area, and the brightness value of this area is (0+H)=H, assuming that H is 80, then at this time " The brightness value of the screen area where "Contacts" is located is 80.

For the above step C, the brightness value of the screen area corresponding to the screen area where the "contact" is located returns to (H-H)=0 after a period of time.

As shown in FIG. 4D , assuming that the area where the predetermined object "call record" in the application interface is located is also a focus area, the switching sequence of the set focus areas is first "contacts" and then "call records". Then when the "call record" needs to be highlighted, the corresponding brightness value of the area where the "call record" is located is 0 (current brightness value) + H=80, and the brightness value of the area where the "contact" is located is 80 (current brightness value )-D=80-50=30, compared with the "call record", the area where the "contact" is located is the second-highest brightness, so that the primary and secondary effects can be achieved.

As shown in Figure 4E, after a preset period of time such as 10s, the highlighted area returns to its original brightness (when the original brightness value is 0, the actual screen has no brightness. content).

In the application scenario of e-book, the e-book application adopts the above-mentioned control method, which can display the content of the article line by line with high brightness according to the user's reading speed, guide the user to read, save the power consumption of the backlight, and improve the use of the battery life.

In the application scenario of playing video, such as playing Youku video, generally the video content is displayed in the middle of the screen, and the rest of the area may display irrelevant content such as advertisements. Therefore, you can set the video display area to high brightness, and the brightness of other areas If the value is set to 0, it can reduce power consumption and only focus on the video without other content interfering with the viewing of the video, which improves the user experience.

It should be noted that the backlight brightness set above is subject to the brightness rules: the maximum does not exceed Dmax, otherwise it is set to Dmax; the minimum is not less than Dmin, otherwise it is set to Dmin. For example, in numerical values expressed as percentages, Dmax may be 100% and Dmin may be 0.

Another embodiment according to the present invention will be described in detail below with reference to FIG. 5A to FIG. 5C .

In this embodiment, the local brightness of the screen can be adjusted according to the user's touch screen operation:

As shown in FIG. 5A , the user slides or wipes the finger on the screen, calculates the area touched by the finger and the trajectory of the slide, takes the operation area touched by the finger as the focus area, and increases the brightness of the backlight unit corresponding to the focus area. For example, assuming that the original brightness of the screen is D, and the area where the "short message" is located is wiped, the new brightness of the wiped area is D1=D+ΔD.

As shown in Figure 5B, assuming that the user has repeatedly wiped the touched operation area, the brightness of the backlight unit corresponding to the repeatedly wiped area can increase with the increase in the number of wipes, for example, in the first wipe The brightness value of the focus area is D+ΔD, and after wiping again, the brightness value of the repeatedly wiped area 502 is D+ΔD+ΔD.

A time interval Δt is set, and after the time Δt elapses, the luminance value of the above-mentioned high luminance area uniformly returns to the original luminance D, as shown in FIG. 5C .

To sum up, for a display screen whose backlight brightness can be controlled individually by region, there are two ways to control the local backlight brightness of the display screen. The screen area of the screen is set to high brightness; the second is to set the area operated by the user to high brightness according to the user's operation on the touch screen.

Therefore, according to the technical solution of the present invention, the backlight brightness of the screen area corresponding to the user's focus area can be controlled, and the controlled screen area can be flexibly adjusted according to the change of the focus area, thereby saving terminal power consumption and extending the battery life of the device; This method of activating the screen can quickly focus on content that needs attention on the screen, such as text messages, call notifications, or prompt boxes.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
