Embodiment Construction

[0017] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in names as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

Abstract

A portable electronic device including a touch sensor and a processing unit is provided. The touch sensor is disposed on or under a display, and uses a power level to generate first touch data for a touch detected thereon when the display is in a sleep state. The processing unit configures the touch sensor to increase the power level to generate second touch data for the touch when determining that the touch corresponds to a predetermined gesture with a first similarity probability greater than a first threshold according to the first touch data, and wakes the display from the sleep state when determining that the touch corresponds to the predetermined gesture with a second similarity probability greater than a second threshold according to the second touch data, wherein the second threshold is greater than the first threshold.

Description

technical field [0001] The present invention relates to the field of touch detection, and more particularly to portable electronic devices and methods for detecting touches on a display screen with adjustable power levels to wake up the display screen. Background technique [0002] To an increasing extent, touch screens are used as an alternative way for users to interact with portable electronic devices such as touch books, mobile phones, tablet computers, media playback devices and gaming equipment, etc. In addition to providing basic display functionality, a touch screen includes one or more touch sensors for detecting contact with an object, thereby providing an alternative method of interacting with the user by using, for example, a pointer, stylus, finger, etc. . In most practical applications, when the user does not interact with the portable electronic device for a period of time, the touch screen can enter the sleep state. In this state, the display function and t...
