Problems solved by technology

Although this method is relatively simple, there are many defects. For example, when the resolution is high, the amount of data increases sharply, and when characters are displayed, it is extremely easy to appear obvious jagged, etc. For electronic devices that have certain requirements for display effects, This character display method does not apply

Embodiment Construction

[0024] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0025] The main idea of ​​the present invention is: according to a plurality of Bezier curve control points of the preset character to be displayed, the outline of the character to be displayed is decomposed into a plurality of Bezier curves, and the number of Bezier curves forming each Bezier curve is obtained. The coordinate values ​​of each contour feature point, and then display the character to be displayed according to the coordinate values ​​of all contour feature points corresponding to the character to be displayed.

[0026] Such as figure 1 As shown, the character display device provided by an embodiment of the present invention includes a storage module 11, a Bezier curve decomposition module 12, a Bezier curve calculation module 13 and a display processing module 14, a Bezier curve decomposition module 12, a Bezier cur...

Abstract

The invention discloses a character display method, a character display device and a safety authentication device. The character display method comprises the steps that according to a plurality of preset Bezier curve control points of characters to be displayed, contours of the characters to be displayed are resolved into multiple Bezier curves; according to a Bezier curve equation and coordinate values of the Bezier curve control points, coordinate values of a plurality of contour characteristic points of each Bezier curve are obtained; according to the coordinate values of all the contour characteristic points corresponding to the characters to be displayed, the characters to be displayed are displayed. According to the technical scheme, compared with the prior art, the character display method, the character display device and the safety authentication device are more complete.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a character display method, a character display device and a safety authentication device. Background technique [0002] With the development of electronic technology, various electronic devices, such as computers, mobile phones, bank USB shields, electronic dictionaries, etc., are widely used in people's daily life, and the display effect has increasingly become a concern of people. [0003] At present, the most commonly used character display method is to use dot matrix characters, that is, to use 0 and 1 dot matrix images to describe fonts. Although this method is relatively simple, there are many defects. For example, when the resolution is high, the amount of data increases sharply, and when characters are displayed, it is extremely easy to appear obvious jagged, etc. For electronic devices that have certain requirements for display effects, This way of displaying characters is n...
