Non-shielded touch hand-held electronic apparatus and controller

Abstract

The subjects of the invention comprise a non-shielded touch hand-held electronic apparatus and a controller. The controller is applicable to the non-shielded touch hand-held electronic apparatus. The controller comprises a driving unit, a sensing unit and a processing unit; the driving unit outputs a driving signal to a touch sensing structure; the sensing unit receives a trigger signal of a trigger event from the touch sensing structure; and the processing unit receives the trigger signal and calculates a plurality of detection points of the trigger event to work out a calculating result, and compares the calculation result with an activation judging condition, wherein when the trigger event satisfies the activation judging condition, the sensing unit allows an input action from the touch sensing structure; the processing unit outputs an operating signal according to the input action; and a central processing unit executes an operation on the hand-held electronic apparatus based on the operating signal. According to the non-shielded touch hand-held electronic apparatus and the controller, the sight of a user in operation is not shielded by fingers, and the problem of the panel scratching is reduced; and in addition, the non-shielded touch hand-held electronic apparatus has the convenience that the electronic apparatus can be operated by one hand and can be touched in a multi-point touch mode.

Description

【Technical field】 [0001] The present invention relates to an electronic device and a controller, in particular to a hand-held electronic device and a controller with non-stop 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 p...

[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
