Embodiment 1

[0036] figure 1 It is an implementation flowchart of the dot matrix text display method provided by the embodiment of the present invention, and is described in detail as follows:

[0037] In step S101, call the display function of dot matrix text;

[0038] In step S102, according to the display function, display the color of the dot matrix text;

[0039] Wherein, when no color is carried in the display function, the pre-stored dot matrix data is called directly.

[0040] In step S103, the pre-stored font data corresponding to the dot-matrix characters is called, and the font data includes the number of storage bits 1 and the coordinate positions.

[0041] Wherein, before step S103, also include:

[0042] Record the number and coordinate position of the storage bit 1 in the dot matrix text;

[0043] Combine the number of records and coordinate positions to generate dot matrix data.

[0044] Wherein, the coordinate position is the position of the storage bit 1 in the latti...

Embodiment 2

[0053] figure 2 It is the implementation flowchart of step S102 of the dot matrix text display method provided by the embodiment of the present invention, and is described in detail as follows:

[0054] In step S201, the color in the display function is identified, and the color includes a text color, or, the color includes a background color and a text color;

[0055] In step S202, when the color in the display function only includes the text color, traverse all points at the specified position on the drawing object, and draw the text color sequentially according to their coordinates;

[0056] In step S203, when the colors in the display function include background color and text color, according to the width and height of the text, the background color is drawn in the specified position area on the drawing object, and at the specified position on the drawing object, Iterate over all points, and draw the text color according to their coordinates in turn.

[0057] In the em...

Embodiment 3

[0059] image 3 It is the implementation flowchart of step S104 of the dot matrix text display method provided by the embodiment of the present invention, and is described in detail as follows:

[0060] In step S301, in the specified area of ​​the display object, at the coordinate position, output the color corresponding to the storage bit 1;

[0061] In step S302, when the number of output reaches the number of the storage bit 1, stop outputting the color corresponding to the storage bit 1, and display the text.

[0062] In the specified area of ​​the display object except for the coordinate position, the color corresponding to the storage bit 0 is output.

[0063] In the embodiment of the present invention, drawing is stopped and text is displayed, which is convenient for users to read.

Abstract

The present invention is applicable to the field of dot matrix text display, and provides a dot matrix text display method and apparatus. The dot matrix text display method comprises: calling a display function of a dot matrix text; displaying the color of the dot matrix text according to the display function; calling pre-stored character mode data corresponding to a dot matrix text, wherein the character mode data comprises the number of storage bits 1 and coordinate locations; and drawing the text in a specified area of a display object according to the number of the storage bits 1 and the coordinate locations. According to the dot matrix text display method and apparatus provided by the present invention, the problem in an existing electronic device that man-machine interaction efficiency cannot be improved due to relatively long time for display screen loading and dot matrix text outputting is solved; and when an electronic device is used normally, the text can be quickly displayed, thereby saving power of the electronic device and improving efficiency of human-machine interaction.

Description

technical field [0001] The invention belongs to the field of dot matrix character display, in particular to a dot matrix character display method and device. Background technique [0002] With the development of electronic equipment in the direction of intelligence, most electronic equipment now has a display screen. For example, devices such as smartphones and tablets, the most popular consumer electronics products, have displays. Loading and outputting dot-matrix characters through the display screen facilitates the completion of man-machine interaction. [0003] However, it takes a long time to load and output dot-matrix characters on the display screen of the existing electronic equipment, which is not conducive to improving the efficiency of human-computer interaction. The reason is that dot-matrix characters are generally stored in bit sequences. For example, an 8x8 dot-matrix text, taking the "A" character as an example, the topology map of its corresponding bit se...
