Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see figure 1 , the present invention provides a technical solution: the method divides the Chinese character list into several groups according to the frequency of Chinese character display, the first group is the most frequently displayed Chinese characters, the second group is used in second place, and the third group is used more frequently. low, and so on. Each Chinese character corresponds to an index word, which is divided into two parts. The fir...

Abstract

The invention discloses a method for displaying Chinese characters through rapid retrieval, which comprises the following steps of 1, establishing groups, grouping Chinese character tables, dividing the Chinese character tables into a plurality of groups according to the display frequency of the Chinese characters, displaying the most frequent Chinese characters in the first group, and enabling the use frequency of the second group to be lower and the use frequency of the third group to be lower in the second group; 2, establishing positions in each group, wherein the number of Chinese characters in each group does not exceed 50, and in five groups, each group contains 50 Chinese characters; 3, retrieving groups, retrieving groups of the Chinese characters; 4, retrieving Chinese charactersin each group, wherein each group has no more than 50 Chinese characters; searching the group corresponding to the Chinese character for at most 50 times to find out the position of the Chinese character; 5, due to the fact that the groups of the Chinese characters with the high use frequency are all in the front, using the Chinese character with the highest use frequency is used, so that the number of times of retrieval is minimum; and 6, displaying the matrix of the Chinese characters through an LCD to find the Chinese characters, so that the code quantity of the program is reduced.

Description

technical field [0001] The invention relates to the technical field of display methods, in particular to a method for displaying Chinese characters through fast retrieval. Background technique [0002] Some electronic devices need to display Chinese characters through the LCD screen to achieve the purpose of human-computer interaction, and for the convenience of displaying Chinese characters, generally dot matrix LCD screens are used. During product design, it is necessary to convert the Chinese character font into a matrix and store it in the product memory. When it needs to be displayed, the address of the Chinese character that needs to be displayed is searched from the memory through the retrieval method, and then the MCU reads out the matrix corresponding to the Chinese character and displays it on the Dot matrix LCD screen. Due to the large number of Chinese characters, searching the matrix corresponding to Chinese characters by sequential retrieval is not fast, and t...
