Problems solved by technology

Due to the very thin display borders on many consumer electronic devices, accidental or false touches may occur, for example, caused by how the device user holds the electronic device
For example, a portion of a user's palm or a portion of a user's clenched fingers may wrap around the surface of the device and extend beyond a very thin border into the touch panel area of ​​the device, thereby causing an accidental touch on the touch panel

Embodiment Construction

[0013] The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. In addition, the following detailed description does not limit the present invention.

[0014] Figure 1A to Figure 1G It is exemplified that the touch panel 105 of the touch screen display of the electronic device 100 is used to perform dynamic touch sensor scanning for false boundary touch input detection. For simplicity, Figure 1A with Figure 1B The touch panel 105 depicted in does not include other components of the touch screen display of the device 100. The electronic device 100 may include any type of electronic device including a touch screen display. For example, the device 100 may include a cellular wireless phone; a satellite navigation device; a smart phone; a personal communication system (PCS) terminal that can combine a cellular wireless phone with data processing, fax, and data communication c...

Abstract

A device, having a touch screen display, performs a mutual capacitance scan of rows and columns of an array of capacitive touch sensors associated with the touch screen display. The device selects a subset of the rows, and a subset of the columns, of the array of capacitive touch sensors, and performs a self capacitance scan of the selected subset of the rows, and the selected subset of the columns, of the array of capacitive touch sensors based on results of the mutual capacitance scan. The device identifies an accidental or false touch input on the touch screen display based on results of the self capacitance scan.

Description

Background technique [0001] Many different types of consumer electronic devices generally include a touch screen, which can be used as an output device that displays images, videos, and / or graphical information, and can also be used as an input touch interface device that receives touch control input from a user. The touch screen (or touch panel or touch panel display) can detect the presence and location of a touch in the area of ​​the display, where the touch can include a touch on the display with a body part (for example, a finger) or with some object (for example, a stylus) . Touch screens generally enable users to directly interact with the content being displayed, rather than indirectly interacting with a cursor controlled by a mouse or touchpad. Touch screens have been widely used in various types of consumer electronic devices, including, for example, cellular wireless phones, personal digital assistants (PDAs), and handheld gaming devices. [0002] The size of touch sc...
