Embodiment Construction

[0053] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] First of all, the term "and / or" that appears in this article is just an association relationship that describes associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: there is A alone, and A exists at the same time and B, there are three cases of B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0055]During the process of proposing the present invention, the applicant found that: the existing screen anti-peeping technology is specifically implemented by the following two implementations.

[0056] For the first implementation, see figure 1 A schematic structural diagram of a display provided by a poss...

Abstract

The invention discloses a brightness adjustment method of a display screen, a display, a device and a readable storage medium. The method comprises the following steps: acquiring ambient light brightness collected by an ambient light sensor; acquiring a first pulse modulation signal generated by a signal generator; calculating a second pulse modulation signal according to the first pulse modulation signal and the ambient light brightness; and adjusting the current backlight brightness of the display screen according to the second pulse modulation signal. According to the invention, the technical problem that the existing peep-proof technology is not beneficial to peep-proof display or is not suitable for special scenes such as darkrooms or outdoors can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for adjusting the brightness of a display screen, a display, a device and a readable storage medium. Background technique [0002] At present, more and more users use electronic devices such as computers and notebook computers to handle daily life and work affairs. But the use scene of electronic equipment is not a closed space, such as public places. When a user is browsing or editing some important information, such as private or confidential information, etc., he does not want this important information to be peeped by others. Therefore, it is necessary to propose a screen peep prevention technology. [0003] In the existing anti-peep technology, it is supported to switch the electronic device from a share mode to a privacy mode, so as to meet the anti-peep requirement of the electronic device. It specifically has the following two implementations: [0004] In th...
