Problems solved by technology

In order to avoid accidental palm touches, the prior art shortens the distance between the point-shaped insulators 20 , but this approach causes the multiple point-shaped insulators 20 to be too close to each other, making it difficult for fingers or stylus to touch the touch panel 10 , while reducing the sensitivity of the touch panel 10

Embodiment Construction

[0024] The matrix multi-touch device according to the embodiment of the present invention has the function of avoiding false palm touches. When the user touches multiple points at the same time, it will not cause operational misoperations due to contact with large-area conductors (such as palms or elbows). .

[0025] see image 3 and Figure 4 , image 3 It is a flow chart of an embodiment of the method for preventing the palm from accidentally touching the touch panel 10 according to the present invention, Figure 4 It is a schematic diagram of the touch panel 10 being touched by the finger and the back of the palm, wherein the block touched by the finger is the first block 24 , and the block touched by the back of the palm is the second block 26 . The method for preventing the palm from accidentally touching the touch panel 10 comprises the following steps:

[0026] Step 42: scanning the multiple areas 28, 30, 32, 34, 36, 38, 40 of the touch panel 10 one by one to detect...

Abstract

The invention relates to a method capable of preventing accident touch on a touch control panel. In order to prevent a palm from accidentally touching the touch control panel, a plurality of areas of the touch control panel is scanned one by one so as to detect a plurality of touched areas among the plurality of areas; and the adjacency relation of the plurality of touched areas is detected so as to determine a plurality of blocks. If the plurality of blocks comprises a large-sized block, the large-sized block is excluded, and a current coordinate is generated according to a small-sized block which is possible to be touched by a finger or a touch control pen.

Description

technical field [0001] The invention provides a method for preventing false touches on a touch panel, in particular to a method for preventing false touches on a matrix multi-point touch panel. Background technique [0002] In the past, there are many technologies for multi-touch in general human-machine interface, among which commonly used technologies such as matrix multi-touch, such as projected capacitive touch (Projected Capacitive Touch) are the most commonly used, projected capacitive touch devices can be controlled by human Fingers, stylus, human hands hold conductors, etc. to operate. Generally, in the habit of writing on medium and large-sized screens, the back of the palm will be placed on the object to be written. For example, when writing on a resistive multi-touch panel, a technology to avoid palm rejection (Palm Rejection) is widely used, but in On the projected capacitive touch panel, when holding a writing tool to input medium and large-sized projected capa...
