Problems solved by technology

[0010] However, since the screen switch in the existing portable personal computer is formed by a protruding structure, it is inconvenient to use, and it is easy to cause the problem that the system cannot operate normally.
[0011] In order to solve the above problems, there is a technology of constructing a screen switch by using a magnetic sensor. However, since the magnetic strength and direction of the magnetic sensor are different, its characteristics are also changed. Even if this technology is used, there is a possibility The problem that caused the screen switch to not work normally
[0012] In addition, the existing screen switch is forced to act with the opening / closing action of the system switch, which may lead to the problem of misoperation

Abstract

A screen switch of portable personal computer consists of a first transducer for sensing module movement angle, a second transducer for sensing finish of module movement, transducer action sensing unit for inputting data sensed by two said transducers and for storing said data, control unit for receiving said data from said sensing unit and for controlling back light power supply of liquid crystal display screen.

Description

technical field [0001] The present invention relates to portable personal computers such as notebook computers and tablet computers, in particular to screen switches for portable personal computers. Background technique [0002] With the continuous development and progress of technology, various personal computers (PCs) such as desktop computers and notebook computers have been successively developed and launched. Among them, notebook computers are computers developed in consideration of the portability of computers. The battery realizes driving the computer. [0003] The size of this notebook computer is getting smaller and lighter, and it has been widely used and popularized. Even if it does not have an AC power supply, it can also drive the system through the charging power supply (DC power supply) of its own battery. [0004] That is, the aforementioned notebook computer has an advantage that it can be used freely regardless of where the user is located. [0005] And, ...
