Embodiment Construction

[0020] The present invention is suitable for displaying character strings with a character width of 8 or 16. In the following embodiments, a character string with a character width of 8 will be used as an example for illustration.

[0021] see figure 1 , assuming that the personal digital assistant device intends to display a character string "ABC" on the screen, and the dot matrix size of each character "A", "B" and "C" in the character string "ABC" is 16× 8 (that is, the length is 16 pixels, and the width is 8 pixels), including a 16×8 “A” character point matrix 21, a 16×8 “B” character point matrix 22, and a 16×8 8 "C" character dot matrix23. In addition, assume that 16 column bytes in the "A" character point matrix 21 are (a1, a2, ..., a16); 16 column bytes in the "B" character point matrix 22 are (b1, b2, ....., b16); and 16 column bytes in the "C" character point matrix 23 are (c1, c2, ....., c16); wherein each column byte includes 8 ones.

Abstract

The method includes the following steps. (1) The dot matrix of each character in the character string is obtained. (2) The dot matrices of all characters in the character string are converted to the single character string dot matrix, where the length of the character string dot matrix is equal to the length of the dot matrix of each character in the character string and the width is equal to thesum of widths of dot matrices of all characters. According to the order of each character in the character string, the column byte in the dot matrix of each character is fetched in ordered cyclic mode to cascade as one column, which then is put into the dot matrix of the character string. (3) The dot matrix of the character string is displayed. The invention provides the effect for displaying thecharacter string fleetly.

Description

technical field [0001] The invention relates to an information technology, in particular to a high-speed character string display method. Background technique [0002] Personal digital assistant device is a small portable intelligent electronic information device, which can provide simple information functions, such as notepad, address book, calculator, calendar, electronic form, database, etc., and utilizes a small LCD screen to display various text and graphic data. [0003] Currently, the font library used by personal digital assistant devices includes two standard character widths: 8 and 16 (unit is pixel); therefore, when displaying a specific character string (character string) on ​​the screen, if each character (character) If the display position (that is, the pixel coordinates on the screen) is a multiple of 8, then no shift operation is required during the display process; otherwise, if it is not a multiple of 8, each character in the string must be One shift oper...
