Abstract

The invention relates to a flat computer with a second display function. The flat computer comprises a CPU (Central Processing Unit) (1), a USB (Universal Serial Bus) communication module (2), an external source signal processing module (3), a display signal switching module (4) and a display (5), wherein the USB communication module (2) is used for finishing communication between an external source signal and the external source signal processing module (3); the external source signal processing module (3) is used for processing the external source signal; the processed external source signal is displayed by adopting the display (5); and the display signal switching module (4) is used for switching the processed external source signal and a display signal output by the CPU (1). The invention further provides a method for realizing the flat computer with the second display function. The flat computer and the method have the benefits as follows: the second display function of the flat computer as a desk computer or a notebook computer is achieved, and a transmission signal is good in antijamming capability and smooth to display.

Description

technical field [0001] The invention relates to the technical field of computer display screens, and more specifically, to a tablet computer with a second display function and an implementation method thereof. Background technique [0002] The tablet computer does not need to be flipped, has no keyboard, and uses a touch screen as a basic input device. It is a small, portable and fully functional personal computer. The appearance of a tablet computer is similar to that of a notebook computer, but a tablet computer is not a pure notebook computer, it can be called a condensed version of a notebook computer. Tablet PCs have a form factor between that of a laptop and that of a handheld, but with more processing power than a handheld. Compared with a notebook computer, it not only has all the functions, but also supports handwriting input or voice input, and its mobility and portability are even better. The current tablet usually has two specifications, one is a dedicated tabl...
