Problems solved by technology

[0002] In normal touch screen design, each grid node corresponds to a coordinate of the touch screen. According to the original design plan, after I paste the knob on the touch screen, the touch chip needs to customize the algorithm first, and divide the knob area into corresponding gradients according to customer requirements. , and then perform calculations based on the changes in the coordinate values ​​calculated by the touch chip, and then obtain the ongoing actions of the knob, such as forward rotation, reverse rotation, and rotation angle. Using this technology, the chip algorithm needs to be customized, and the flexibility is insufficient.

Embodiment 1

[0024] see figure 1 , a knob touch screen, a knob touch screen includes a touch area and a knob control area, the touch area includes a touch screen 1, the knob control area includes a knob 2, and the knob 2 includes a base 21, a rotating part 22 and a touchpad23 , the base 21 is fixed on the touch screen 1, the rotating part 22 can rotate around the center of the base 21, the rotating part 22 is arranged on the upper surface of the base 21, the touch pad23 is arranged on the knob 2, a special pattern11 is arranged in the touch area, and the special pattern11 is used to feel the position of touch pad23.

[0025] The special pattern 11 is located on the bonding area of ​​the knob 2 and the touch screen 1 .

[0026] The special pattern11 has a special electrode shape.

[0027] The shape of the dedicated pattern 11 may be a ring.

[0028] The base 21 is fully or partially fixed within the screen functional area of ​​the touch screen 1 .

[0029] The touch screen 1 is a capaci...

Embodiment 2

[0031] see image 3 , set the 9 positions of k1-k9 on knob 2, and define the coordinates of the 9 positions as (X20,Y31);(X21,Y31);(X22,Y31);(X23,Y31);(X24 , Y31); (X25, Y31); (X26, Y31); (X27, Y31); (X28, Y31). , when the touchpad23 is rotated on the (X20, Y31) coordinates, the host thinks that the gear at this time is the first gear, and then processes the signal to adjust the air volume, and so on; at the same time, the host can pass the coordinates whether to rotate from K1 to K2 or Rotate K1 to K9 to determine whether the rotating direction of the knob is forward or reverse.

[0032] Concrete mode of operation of the present invention is as follows:

[0033] After power-on, the touch IC performs reset initialization and corresponding self-test to check whether the normal touch area and the knob sensing area are normal;

[0034] After the touch IC starts normally, it detects whether there is a finger operation or a 2-rotation action of the knob according to a certain fr...

Abstract

The invention provides a knob touch screen, the knob touch screen comprises a touch area and a knob control area, wherein the touch area comprises a touch screen, the knob control area comprises a knob, the knob comprises a base, a rotating part and a touch pad, the base is fixed on the touch screen. The rotary component can rotate around the center of the base, the rotary component is arranged on the upper surface of the base, the touch pad is arranged on the rotary knob, a special pattern is arranged in the touch area, and the special pattern is used for sensing the position of the touch pad. The corresponding special pattern is designed in the knob attaching area, so that a touch IC algorithm does not need to be customized independently, the special pattern is used as an independent annular key for recognition, and a host end recognizes the on-going action and the rotation angle of the knob according to the change of report points of several keys.

Description

technical field [0001] The present invention mainly relates to the technical field of touch screens, in particular to a knob touch screen. Background technique [0002] In normal touch screen design, each node of the grid corresponds to a coordinate of the touch screen. According to the original design plan, after I paste the knob on the touch screen, the touch chip needs to customize the algorithm first, and divide the knob area into corresponding gradients according to customer requirements. , and then perform calculations based on the changes in the coordinate values ​​calculated by the touch chip, and then obtain the ongoing actions of the knob, such as forward rotation, reverse rotation, and rotation angle. Using this technology, the chip algorithm needs to be customized, and the flexibility is insufficient. Contents of the invention [0003] The present invention mainly provides a knob touch screen to solve the technical problems raised in the background art above. ...
