Embodiment Construction

[0026] like figure 1 Shown is a schematic flow chart of a segmented liquid crystal display driving method according to an embodiment of the present invention, including: an assignment step 100, a first generation step 102, a second generation step 104, an acquisition step 106, and a driving step 108. Wherein the assignment step 100 is used to extract each display segment information from the logic diagram of the segment type liquid crystal display, and assigns a two-dimensional coordinate value to each display segment; the first generation step 102 is used to generate a character segment control register, a mapping table index The macro definition of value and mask, and / or generate the macro definition of graphic symbol segment control register, control bit and operation; The second generation step 104 is used to generate the header file that contains above-mentioned macro definition information, add this header file to liquid crystal display In the engineering of the screen ...

Abstract

The invention discloses a display driving method and device for a segment type liquid crystal display. The method includes an assignment step, a first generation step, a second generation step, an acquisition step and a driving step. According to the display driving method and device for the segment type liquid crystal display, time spent in repeatedly reading a segment type LCD logic diagram to acquire relevant control information and checking display control can be saved, time spent in manually compiling macro definition is shortened, a control program does not need to be compiled again, acquired information is high in accuracy, and transportability is very high.

Description

technical field [0001] The invention relates to a display driving method and device, in particular to a segment liquid crystal display driving method and device. Background technique [0002] With the continuous development of electronic technology, a large number of portable intelligent electronic devices have been widely used and play an indispensable role in people's daily life. Most of such portable smart electronic devices (such as electronic sphygmomanometers, health scales, etc.) use relatively low-cost segment LCDs (liquid crystal displays) to display data such as blood pressure and weight. The current segment LCD itself does not have a driving circuit, nor does it have a display buffer, and it needs to be connected with an external driver chip with a display buffer to realize the display. In general, segment LCDs are specially customized according to the display requirements of some specific devices (such as electronic blood pressure monitors). Usually, there are ...
