Portable laptop shading dust-proof cover

Abstract

The invention provides a portable laptop shading dust-proof cover. The dust-proof cover is characterized in that the front half portion of the top can rotate around a shaft freely, a magnet unit is arranged on the shaft, the top is equivalent to a plane when a sector region is expanded, the magnet plays a role in fixation, and snapping grooves are formed in contacting portions between the left, the right and the top and the laptop, so that the cover can be fixed on the laptop conveniently, the sector region is equivalent to a fan and can be opened and closed freely. The dust-proof cover can be used for shading light when being opened and can be used for proofing dust when being closed. The dust-proof cover has the advantages that most light is shaded when the cover is opened, so that the laptop liquid crystal display is clear, the liquid crystal display required brightness is reduced, the laptop power consumption is reduced, and the laptop service life is prolonged; the cover is equivalent to a computer holding bag to cover the computer, and a dust-proof effect is provided.

Description

Technical field [0001] The invention relates to a device for shielding the ambient light of a notebook computer display screen to improve the display effect, and wrapping the computer to prevent dust, in particular to a portable notebook computer light-shielding and dustproof cover. Background technique [0002] Nowadays notebook computers are quite popular, and the LCD screens used in notebook computers are displays that rely on their own backlight to emit light. Because the power of the backlight cannot be too high, the LCD screen works in places with strong light intensity. When the screen is idle, the screen is relatively dim, the content displayed is not clear, and the display effect is not good. Therefore, users can only improve the backlight to achieve a better display effect, but this not only consumes more notebook computer power, but also has great damage to the user’s eyes. For a long time, the damage to the user’s eyes is immeasurable. . Today’s notebooks are be...

AI Technical Summary

Problems solved by technology

[0002] Laptops are now quite popular, and the LCD screens used in laptops are displays that rely on their own backlight to emit light. Since the power of the backlight cannot be made too high, the LCD screen works in a place with strong light intensity. When the screen is idle, the screen is relatively dim, the displayed content cannot be seen clearly, and the display effect is not good

Therefore, the user can only increase the backlight to achieve a better display effect, but this not only consumes more power of the notebook computer, but also causes great damage to the user's eyes. If this happens for a long time, the damage to the user's eyes is immeasurable

Today's notebooks are becoming more and more exquisite and smaller, but dust entering the notebook computer will have a great impact on the running speed of the notebook computer. At the same time, because the computer is too small, it is not easy to remove dust. Dust becomes very important
