Description

A method and device for adjusting screen brightness of a touch screen terminal

Technical field

The invention belongs to the technical field of touch screen terminals, and in particular relates to a method and device for adjusting screen brightness of a touch screen terminal.

Background technique

With the development of technology, touch screen terminals are widely used in life. The product types are diverse, including but not limited to smartphones, smart watches, tablets and other devices. Because the ambient light intensity is diverse and changing, as well as personal preferences and other factors, the screen brightness needs to be adjusted.

Due to the advancement of technology and people's pursuit of space utilization of display devices, current conventional mobile phones, smart watches, etc. have a tendency to increase the screen-to-body ratio and narrow the borders.

There are currently four common methods of adjusting screen brightness. The first is to adjust the screen brightness by detecting the intensity of external light through the photosensitive element; the second is to display the slide bar, which is generally not close to the edge of the screen, and adjust the screen brightness by sliding the finger on the slide bar; the third is to adjust the screen brightness by sliding the slide bar with your finger. buttons to adjust the screen brightness, such as the brightness adjustment keys on a computer display; the fourth method is to set an area of the screen as a brightness adjustment area, and adjust the screen brightness by setting the gesture sliding direction, which is often used in video applications (APP) .

technical problem

Among the above four solutions, the first one is very common. Generally, mobile phones have automatic brightness adjustment options. Because it is a program setting, it is easy for the adjustment frequency to be too slow or too fast, unable to understand personal preferences, and unable to adjust the screen display. The content is automatically adjusted, etc., causing discomfort to the human eye or irritability.

The second solution is also very common. In the mobile phone settings area, set the slider and adjust the brightness by sliding your finger. The biggest problem with this solution is that it ignores the ambient light intensity. When the external environment is very bright and the screen is dark, the user needs to adjust the screen brightness to see the screen clearly. However, the brightness adjustment slider needs to be premised on the user being able to see the screen clearly. Confirm its position; when the environment is very dark and the mobile phone screen is very bright, such as when answering a phone call at night, the screen is dazzling. The user needs to dim the screen to avoid strong light stimulation, and then needs to endure the dazzling brightness to determine the sliding brightness adjustment. The position of the bar. In addition, this solution requires calling up the settings page and then adjusting the brightness, which is a redundant step.

The third solution is commonly seen on computer monitors. This solution requires additional parts, which increases the cost of the equipment; in addition, the parts need to occupy a certain volume. Generally, mobile phones, tablets, smart watches, etc. rarely use this type of design.

The fourth solution, common in video applications (APP), is to slide up the display area to increase the screen brightness and slide down to decrease the screen brightness. This type of scheme generally sets the area to the entire screen, so it will overlap with other interactive gestures and is rarely used outside of such applications. In addition, because the area is the entire screen, there is no clear reference to the minimum and maximum brightness value points. It is difficult for users to confirm whether the brightness has been adjusted to the lowest or highest brightness.

Technical solutions

Considering the characteristics of many current mobile phones, watches, tablets, etc. with narrow borders, the touch screen area adjacent to the edge of the device frame is set as the brightness adjustment area, and the adjacent touch screen area at one end of the edge is set as the endpoint corresponding to the lowest brightness value, and the other end Set to the endpoint corresponding to the highest value, and the touch screen area between the two ends is set to the brightness adjustment slider.

beneficial effects

You can adjust the screen brightness by relying on the movement and touch of your fingers when you cannot see the screen clearly, and you can easily set the brightness to the minimum or maximum value; the operating area takes up little space and is less likely to conflict with other interactive gestures; There is no need to call the setting menu, which reduces the user's operating steps and time; it uses the existing technology of the touch screen and does not require other parts, reducing the cost of the equipment.

Best Mode of Carrying Out the Invention

Taking the edge formed by the edge of the touch screen and the shell surrounding the touch screen as a reference, the touch area adjacent to this edge is set as the brightness adjustment receiving area; the range of this area can be adjusted according to the size of the touch screen and user preference; The brightness adjustment receiving area adjacent to each endpoint is set to the area corresponding to the maximum value and the minimum value of the brightness; for a touch screen terminal with multiple edges, there can be multiple corresponding brightness adjustment receiving areas, and any one or more of them can be selected. As a brightness adjustment receiving area; when the screen wakes up, the user needs to adjust the screen brightness, use the finger touch to sense the edge adjacent to the set brightness adjustment receiving area, touch the edge with the finger and slide along this reference object in the brightness adjustment receiving area , at this time, the terminal obtains the real-time position of the finger, and converts the ratio of the length of the line segment connecting the position and the endpoint with the lowest edge value to the edge length into a brightness value that is the same ratio as the maximum brightness value, and Sets the screen brightness value to this brightness value.

In order to avoid accidental touches, it is recommended to set a moving distance as a threshold. Only when the threshold is exceeded and the movement is within the set area, the brightness will be adjusted.

The area between the two endpoints does not need to be continuous. For some types of devices, there may be lenses or other parts in the middle. It is recommended to retain the touch capability of this area to create a consistent experience.

For common mobile phones, the location of this area can be set in the status bar area of the mobile phone, which is the area that displays time, signal strength, and battery power, and overlaps with this area. For products such as tablet computers, if there is a status bar or taskbar, this area can also be set to overlap it.
