Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0013] ginseng figure 1 As shown, the software driving method of the stroke-type liquid crystal display provided by the present invention, the present embodiment takes the LCD digital tube driving method as an example, the meaning list of the strokes is as follows, and the meaning list of the strokes refers to each BIT (binary digit) of the display buffer Represents the meaning of the paragraph, starting from address 0 of the video memory:

[0014] enum {

[0015] LCD_SEG_DATA000 = 0,

[0016] LCD_SEG_DATA001 = 1,

[0017] LCD_SEG_DATA014 = 14,

[0018] LCD_SEG_DATA015 = 15,

[0019] LCD_...

Abstract

The invention provides a stroke segment type liquid crystal display screen software driving method which comprises the steps that a number list to be displayed is obtained from a display number sequence; a stroke segment type LCD nixie tube display code list is checked, and a nixie tube code corresponding to each number is obtained; a stroke segment list of a nixie tube corresponding to each number is checked, and records in the stroke segment list form the BIT serial numbers of sections of the nixie tube in a display cache; and the corresponding value of the BIT serial numbers in the display cache of the nixie tube stroke segment list corresponding to displayed numbers are modified in sequence. Compared with the prior art, stroke segment type liquid crystal display screen driving is easy and clear, transplantation is convenient, and the driving problem that related stroke segments are too scattered is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a driving method for a segment type liquid crystal display screen. Background technique [0002] In reality, a large number of portable devices and industrial control devices use low-cost pen-segment LCD (liquid crystal display) to realize the display function. Although the pen-segment LCD is cheap, it does not have a driving circuit itself, let alone a display buffer. It needs an external driver chip. Generally, the driver chip will have a display buffer. Pen-segment LCDs are often customized for certain specific devices. The meanings represented by each pen segment are relatively random, and are limited by LCD production, often resulting in a group of related pen segments (for example, each segment of an LCD 7-segment digital tube) is Scattered, controlled by discontinuous row and column driver pins, even if a driver chip with display buffer is used, the control o...
