Problems solved by technology

[0002] With the development of touch technology, touch screens are more and more widely used. While displaying images, touch screens can also display virtual buttons and perform touch operations, which not only saves the space of traditional physical buttons for the device, but also provides Provides a better operating experience than traditional physical buttons, but the general virtual buttons are always displayed on the touch screen, occupying the space on the touch screen for a long time

Embodiment Construction

[0017] See figure 1 In a preferred embodiment of the present invention, a touch screen virtual key display system includes a touch recognition unit 10, a timing unit 20, and a virtual key display unit 30, the touch recognition unit 10 and the virtual key The display unit 30 is connected to the timing unit 20 respectively.

[0018] See figure 2 , Which is a preferred embodiment of the touch recognition unit 10, the touch recognition unit 10 includes a set of first electrode lines 11 extending in a horizontal direction and a set of second electrode lines 12 extending in a vertical direction, The first electrode line 11 and the second electrode line 12 are arranged perpendicular to each other on the touch screen. The intersection of the two sets of electrode lines 11 and 12 forms a capacitance. When a finger or a stylus touches the touch screen, the touch point is affected The size of the nearby capacitance, based on the change in capacitance, determines that a finger or stylus tou...

Abstract

The invention discloses a touch screen virtual key display system. The system comprises a touch identification unit. The touch identification unit is used for identifying whether a finger or a touch pen touches a touch screen. The touch screen virtual key display system also comprises a timing unit and a virtual key display unit. The timing unit is used for timing the duration that the finger or the touch pen touches the touch screen. The virtual key display unit is used for displaying the virtual key on the touch screen when the duration is greater than a preset value. The invention also comprises a touch screen virtual key display method.

Description

Technical field [0001] The invention relates to a system and method for displaying virtual keys, in particular to a system and method for displaying virtual keys on a touch screen. Background technique [0002] With the development of touch technology, touch screens are more and more widely used. While displaying images, the touch screen can also display virtual buttons and perform touch operations. This not only saves the space of traditional physical buttons for the device, but also provides It has a superior operating experience than traditional physical buttons, but the general virtual buttons are always displayed on the touch screen, occupying space on the touch screen for a long time. Summary of the invention [0003] In view of the above, it is necessary to provide a touch screen virtual key display system and method that does not always occupy the space of the touch screen. [0004] A touch screen virtual key display system includes a touch recognition unit, the touch recog...
