Controller

Abstract

The invention discloses a controller applicable to a gear-free touch control handheld type electronic device. The handheld type electronic device comprises a touch control outer cover, a panel, a controller and a central processing unit. The touch control outer cover is provided with an outer cover body and a touch control sensing structure. The controller, the panel and the touch control sensing structure are in signal connection with one another. The outer cover body is arranged on the other side, opposite to the panel, of the handheld type electronic device. The controller comprises a driving unit, a sensing unit and a processing unit. The driving unit outputs a driving signal to the touch control sensing structure. The sensing unit receives double-finger sliding from a single hand holding the handheld type electronic device. The processing unit generates a selected signal, generates a transmitting signal according to the double-finger sliding, and transmits the selected signal and the transmitting signal to the central processing unit. The central processing unit controls the panel to display selected data according to the selected signal, and transmits the selected data to a target electronic device according to the transmitting signal. By means of the gear-free touch control handheld type electronic device, fingers can be prevented from shielding the sight of a user in an operation process, panel scratches are reduced, and the gear-free touch control handheld type electronic device can be operated and controlled by a single hand in a multi-touch way.

Description

technical field [0001] The present invention relates to a controller, in particular to a controller suitable for a hand-held electronic device with no barrier touch. Background technique [0002] With the continuous advancement of science and technology, various information devices with communication functions are continuously introduced, such as mobile phones, tablet computers, ultra-thin notebook computers, and handheld communication devices such as satellite navigation. In addition to generally using a keyboard or a mouse for input or manipulation, using touch technology to manipulate various information devices is a very intuitive and popular manipulation method. In particular, the touch display device has a humanized and intuitive input operation interface, so that users of any age can directly select or manipulate the information device with their fingers. [0003] In the known handheld electronic devices with touch function, the touch operation is performed directly ...

[0004] However, this approach will increase the size of the electronic device, which goes against the development trend of today's handheld electronic devices towards light, thin, short, and small, making it difficult to implement in smaller tablet computers, mobile phones and other products.

[0005] In addition, the above-mentioned panels need to introduce rare-earth transparent touch sensing structures such as indium tin oxide (ITO), so that the panels can have both touch and display functions at the same time. , transmittance, visibility, and poorer conductivity than metals, so a transparent touch sensing layer made of rare earth metal indium ore is not a good choice; even if a metal grid with high conductivity is used as a touch sensor The measured structure will also have the visibility problem of metal grid interference fringes

Furthermore, when users use handheld electronic devices under sunlight or strong light sources, the sunlight readability of the panel has always been an issue that cannot be effectively solved.

[0006] In addition, according to the aforementioned content, since the hand-held electronic device needs to be controlled or operated by touching the touch panel with a finger or a stylus, the panel is often scratched.

Furthermore, it is known that most of the handheld electronic devices with touch function need to hold the handheld electronic device with one hand while operating the handheld electronic device, while the other hand performs touch operation on the panel. If there is no control operation, the user can only use the thumb to perform touch control. In this way, both the touch efficiency, accuracy and convenience will be reduced, and the multi-finger touch gestures held by one hand at the same time cannot wirelessly transmit data to the Other electronic devices to expand the convenience of user community data sharing
