Problems solved by technology

However, due to cost considerations, the projection device installed on the keyboard is usually not a high-end projection device, so the sharpness of the generated 2D projection image is not ideal
In addition, although this type of keyboard provides a 3D projection function, components such as polarizers must be added during operation to produce a 3D projection effect, which is not conducive to the simplification of the structure of the keyboard device.

Abstract

The invention provides an input device with a projection function, which includes a first input device and a second input device. The first input device has a first projection unit and the second input device has a second projection unit. The first projection unit and the second projection unit are used for performing 2D projection or 3D projection. When the projection directions of the first projection unit and the second projection unit are the same, the first projection unit and the second projection unit perform 2D projection. When the projection directions of the first projection unit and the second projection unit are perpendicular, the first projection unit and the second projection unit perform 3D projection. The invention provides sharper 2D projected images and the function of simplifying the structure of the input device.

Description

technical field [0001] The present invention relates to an input device, in particular to an input device with projection function. Background technique [0002] In recent years, more and more users use portable electronic devices, such as mobile phones or tablet computers, to carry and share information. Compared with notebook computers, portable electronic devices have the advantage of being convenient to carry. However, since the portable electronic device inputs data by means of touch input. Compared with the keyboard, the way of entering data on the touchpad is slow and inconvenient. [0003] In order to improve this problem, many portable input devices have been developed in the prior art. The volume of this input device is smaller than that of a keyboard used in general computers, but it can provide the same input method as the keyboard input operation, so it can solve the problem of inconvenient data input in portable electronic devices. [0004] In addition to t...
