Embodiment 1

[0041] Example 1: as figure 1 As shown, this embodiment uses the method of hollow display to display the virtual keyboard characters on the touch screen.

[0042] The display device provided in this embodiment includes a virtual keyboard character display position determination unit, a calculation unit and a display unit 1 .

[0043] Such as figure 1 As shown, the position determination unit obtains the implicit user-invisible key grid layout state of the virtual keyboard, and determines the display position of the character "P", which is in the first virtual key grid on the right side of the second row of the virtual keyboard.

[0044] Such as figure 1 As shown, after the position determination unit acquires the character "P", the calculation unit calculates the closed interval of the character through the Bezier curve of the character "P" in the vector font, and determines the display outline of the character.

[0045] After determining the position and outline interval o...

Embodiment 2

[0049] Such as figure 2 As shown, in this embodiment, the touch screen virtual keyboard characters are displayed using the brightness increase and decrease display method.

[0050] The background picture is medium gray. After determining the position and contour interval of the character "P", the calculation unit converts the color coding value of the pixel 2 in the right half of the contour interval of the character "P" by adding a brightness offset to obtain light Gray color coding value; the calculation unit converts the color coding value of the left half pixel 3 in the outline interval of the character "P" minus a brightness offset to obtain a dark gray color coding value.

[0051] The display unit draws and displays dark gray and light gray pixel information in the contour interval of the character "P" converted by the calculation unit. The user can know that the key grid area is the keystroke area of ​​the character "P" by obtaining the brightness comparison between t...

Embodiment 3

[0054] Such as image 3 As shown, in this embodiment, the intermittent display method is used to display the virtual keyboard characters on the touch screen.

[0055] After determining the position and contour interval of the character "P", the calculation unit converts the color coding value of each pixel in the contour interval of the character "P" to black of "R=0, G=0, B=0", and determines that the state is Display state A: the calculation unit converts the color coding value of each pixel in the outline interval of the character "P" into the original color coding value of each pixel in the background picture, and determines this state as display state B. After display state A is kept for 2 seconds, it will be converted to display state B, and after display state B is maintained for 5 seconds, it will be converted to display state A. The two states cycle alternately.

[0056] The display unit draws and displays the display state A and display state B converted by the calc...

Abstract

The invention relates to a display method and a display device of portable electronic equipment, in particular to a method and a device for displaying a symbol identifier on a virtual keyboard. In the method, with change of pixel color and brightness, by using a hollow-out and alternate display method, the information of a background picture which is covered by the symbol identifier of the virtual keyboard is provided for a user, and during display of the virtual keyboard, the background picture is displayed to the largest extent, so that the completeness and definition of the information of a foreground picture and the background picture are realized, and a human-computer interaction experience of the portable electronic equipment is greatly improved.

Description

technical field [0001] The invention relates to a display method and device of a portable electronic device, in particular to a display method and a display device for symbol marks on a virtual keyboard. Background technique [0002] Virtual keyboards are mainly used on portable devices such as tablet computers and mobile phones. When displaying virtual keyboards on the screen, a large area covers the background interface, which occupies a limited display interaction space and maximizes the demand for interactive interfaces. Interface with small devices The limited contradictions are more prominent and sharp. At present, there is a method of using a transparent keyboard interface to solve the problem of the virtual keyboard covering the background interface, but the overlapping of the virtual keyboard interface and the background interface will still cause color mixing, which will affect the overall visual effect of the interface. For example, Chinese patent application 200...
