Invention Description (1) [Invention Field] The present invention relates to an information technology, and more particularly to a high-speed string display method, which can be applied to wisdom The type of electronic information device, for example, a Personal Digital Assistant (PDA), is used to display a character string more quickly on the screen of the personal digital assistant device. BACKGROUND OF THE INVENTION A personal digital assistant device is a small portable intelligent electronic information device that provides simple information functions such as a notepad, an address book, a computer, a calendar, a spreadsheet, a database, and the like. Use a small LCD display to display a variety of text and graphic data. At present, the font used by the personal digital assistant device includes two standard character widths: 8 and 16 (in pixels); therefore, if a specific character string is displayed on the screen, if each of the characters If the display position of the character (ie, the pixel coordinates on the screen) is a multiple of 8, the shift operation is not required during the display; otherwise, if it is not a multiple of 8, it must be in the string. Each character is subjected to a shift operation. Therefore, it is necessary to repeat the shift operation a plurality of times to display each of the sub-elements in the string one by one. However, this repeated shift operation will obviously make the display speed slower. SUMMARY OF THE INVENTION In view of the above-mentioned disadvantages of the prior art, the main object of the present invention is to provide a high-speed string display method which can be applied to a personal digital assistant device for displaying a character string more quickly.

On the screen of the invention (2). Broadly speaking, the string display method of the present invention comprises at least the following steps: (1) obtaining a dot matrix of each character in the string, and (2) performing a one-point matrix conversion procedure for using the string in the string The dot matrix of all the characters is converted into a single string dot matrix; wherein the length of the dot matrix is equal to the length of the dot matrix of each character in the string, and the width thereof is equal to the length of the string The total width of the dot matrix of all characters; and wherein the column bytes in the dot matrix of each character are fetched and concatenated into a column according to the sequential H-sequence of each character in the string. And then placing it into the string matrix; and (3) displaying the string matrix on the screen of the smart electronic information device. The character string display method of the present invention is characterized in that a dot matrix of a plurality of words in a string is converted into a single dot dot matrix, and the dot matrix is displayed on the screen. Compared with the prior art, since the string display method of the present invention only needs to perform a shift operation at most, the string can be displayed on the screen without requiring multiple shift operations as in the prior art. , so it provides a faster string display.
