Abstract
The invention discloses a method for automatically adjusting brightness of a display to a battery charge and discharge balance point, which comprises the following steps: 1) starting up the computer and displaying pictures; 2) start balance point test: if the battery in the display is detected to be in a discharging state, gradually reducing the backlight brightness value brightness of the display, checking whether the battery is in a charging state or not every time the backlight brightness value brightness is reduced by one step, and stopping backlight adjustment until the battery is in the charging state; if the battery in the display is detected to be in the charging state, the backlight brightness value brightness of the display is gradually increased, whether the battery is in the discharging state is checked every time the backlight brightness value brightness is increased by one step, if the battery is in the discharging state, the backlight brightness value brightness is decreased by one step, the battery is in the charging state, and the backlight adjustment is stopped. Even under the condition that the Type-C power supply is insufficient, the display can still display pictures and maintain the condition that the battery is not consumed, so that the durability of the battery in the display is effectively improved.
Description
Technical Field
The invention relates to the technical field of displays, in particular to a method for automatically adjusting brightness of a display to a battery charge and discharge balance point.
Background
The Type-C display does not have an independent power input, but operates by the power supplied from the Type-C terminal. And the Type-C display of built-in battery, the electricity by Type-C input supplies the display, also can be internal battery charging simultaneously.
The existing Type-C display with a built-in battery has the following defects: 1. when the current which can be provided by the Type-C is not enough for the display (without charging the battery), the Type-C display is complemented by the internal battery, but correspondingly, the battery is in a power consumption state, and finally, the battery is used up and cannot be used; 2. adjusting the brightness of the display to a low level can reduce the possibility of using the built-in battery, but the brightness is low, the picture is poor in light perception, and the user does not know how low to adjust the brightness to avoid using the power of the built-in battery.
Disclosure of Invention
The invention aims to provide a method for automatically adjusting brightness of a display to a battery charge-discharge balance point, which can still display a picture and maintain no power consumption of a battery under the condition of insufficient Type-C power supply.
In order to achieve the purpose, the invention adopts the following technical scheme:
the method for automatically adjusting the brightness of the display to the balance point of the battery charge and discharge comprises the following steps:
1) starting up the computer and displaying pictures;
2) start of balance point test:
if the battery in the display is detected to be in a discharging state and the backlight brightness value brightness of the display is larger than zero, gradually reducing the backlight brightness value brightness of the display, and checking whether the battery is in a charging state or not every time the backlight brightness value brightness is reduced by one step until the battery is in the charging state, and stopping backlight adjustment;
if the battery in the display is detected to be in a charging state and the backlight brightness value brightness of the display is not the maximum value, gradually increasing the backlight brightness value brightness of the display, checking whether the battery is in a discharging state or not every time the backlight brightness value brightness is increased by one step, and if the battery is in the discharging state, decreasing the backlight brightness value brightness by one step to enable the battery to be in the charging state and stopping backlight adjustment.
Further, the battery is monitored in a discharging state or a charging state by a Gauge IC chip.
By adopting the technical scheme, even under the condition of insufficient Type-C power supply, the display can still display the picture and maintain the battery to be free of power consumption, so that the durability of the battery in the display is effectively improved.
Drawings
The invention is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a flow chart of the present invention.
Detailed Description
As shown in fig. 1, the method for automatically adjusting the brightness of the display to the balance point of the battery charge and discharge includes the following steps:
1) starting up the computer and displaying a picture;
2) start balance point test:
if the battery in the display is detected to be in a discharging state and the backlight brightness value brightness of the display is larger than zero, gradually reducing the backlight brightness value brightness of the display, and checking whether the battery is in a charging state or not when the backlight brightness value brightness is reduced by one step, and stopping backlight regulation until the battery is in the charging state;
if the battery in the display is detected to be in a charging state and the backlight brightness value brightness of the display is not the maximum value, gradually increasing the backlight brightness value brightness of the display, checking whether the battery is in a discharging state or not every time the backlight brightness value brightness is increased by one step, and if the battery is in the discharging state, decreasing the backlight brightness value brightness by one step to enable the battery to be in the charging state and stopping backlight adjustment.
In the invention, the battery is monitored in a discharging state or a charging state by the Gauge IC chip.
By adopting the technical scheme, even under the condition of insufficient Type-C power supply, the display can still display the picture and maintain the battery to be free of power consumption, so that the durability of the battery in the display is effectively improved.
While the invention has been described in connection with the above embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, which are illustrative and not restrictive, and that those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
Claims (2)
