Multifunctional touching controlling board and controlling method thereof

Abstract

The invention relates to multifunctional touch pad and its controlling method. It includes one the first key press set at the middle of the touch pad, and at least one the second key press set at its edge. While pressing the first key press, if at least one the second one is also pressed, the touch pad will firstly touch off the first key press function, neglect the pressed second one.

Description

technical field [0001] The invention relates to a multifunctional touch panel, in particular to a touch panel capable of supporting one-dimensional and two-dimensional modes and integrating key functions and a control method thereof. Background technique [0002] Recently, due to the advantages of simplicity, portability and low cost, touch panels have been widely used in various electronic products to replace original input devices. The current touchpad has two-dimensional mode and one-dimensional mode. Fig. 1 and Fig. 2 are the sensors 100 and 101 of the two-dimensional mode touch panel of two common shapes, which have a plurality of horizontal direction sensing lines 102 and vertical direction sensing lines 104, when the finger touches the two-dimensional touch panel When the touch position is touched, the sensing lines 102 and 104 transmit information to the host connected to the two-dimensional touch panel, thus knowing the coordinates of the touched position. When the...

Problems solved by technology

Although this one-dimensional touchpad can clearly determine the positive and negative directions, it cannot provide a variety of functions like a two-dimensional touchpad, such as handwriting recognition. If you want to add additional functions, you must add additional buttons or other functions. input device, which will increase the cost

[0005] 4 and 5 are schematic views of the front and back of the input device 108 currently used on the iPod, which uses the single-dimensional sensor 110 disclosed in US Patent Application Publication No. 2004 / 0252109. When the sensor 110 is rotated left or right, the menu can be scrolled or the volume can be adjusted. A button 112 and 114 are respectively provided in the four directions and the center of the sensor 110 to provide additional functions, such as activation / Stop, fast forward, reverse, menu and confirmation, because the sensor 110 is a ring, so the center button 112 is self-contained and cannot achieve the effect of integral molding with the sensor 110, if the shape of the sensor 110 is a complete circle , although the effect of one-piece molding can be achieved, when the center button 112 is pressed, the sensor 110 will be depressed with the finger pressing. If the pressed position deviates from the center position, other buttons 114 may be touched by mistake, as shown in Figure 6 indication, resulting in incorrect operation
