COG liquid crystal display module convenient to use

Abstract

The invention discloses a COG liquid crystal display module convenient to use. The module comprises an LCD display screen and an FPC panel, wherein the LCD display screen is bound through a COG IC chip, the COG IC chip is in electric connection with an external control chip through the FPC panel, a backlight source is arranged on the lower portion of the LCD display screen, the COG IC chip is of the model of ML1001-2U, the LCD display screen is provided with a plurality of figure-eight codes, each figure-eight code is divided into a plurality of stroke segments, column electrodes on the COG IC chip are in electric connection with the stroke segments of the figure-eight codes respectively, and the stroke segments on the figure-eight codes are sequentially in wiring connection through row electrodes to form an adapter ring with a notch. The stroke segments on the figure-eight codes are sequentially in wiring connection through the row electrodes to form the adaptor ring with one notch, the adaptor ring is provided with only one notch, and accordingly gaps between light-emitting points on the figure-eight codes displayed on the stroke segments are tight, the COG IC chip can conveniently and quickly drive the stroke segments to display, the resolution of the codes is improved, and meanwhile, the sizes of the figure-eight codes can be shortened and the size of the whole display module is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a portable COG liquid crystal display module. Background technique [0002] Liquid crystal display modules have gradually occupied the mainstream of display products due to their advantages of light and thin size, small footprint, and low radiation. At present, the requirements for display modules are getting higher and higher: as small as possible, wider operating temperature range, wider Good contrast, wide viewing angle range, etc. The existing liquid crystal display modules on the market are LCD products driven by the Multiplex method. This driving method has defects such as low contrast, small viewing angle range, and small operating temperature range; There are the following defects in size: 1) The overall size of the 8-character code is relatively large, and the area occupied by the display screen is relatively large, which in turn causes the entire display module to...

Problems solved by technology

The existing liquid crystal display modules on the market are LCD products driven by the Multiplex method. This driving method has defects such as low contrast, small viewing angle range, and small operating temperature range; There are the following defects in size: 1) The overall size of the 8-character code is relatively large, and the area occupied by the display screen is relatively large, which in turn causes the entire display module to be large in size, making it very inconvenient to carry and install; 2) Because the viewing angle display is too small , in order to make the digital display effect meet the user's vision, the row electrode part of the driver chip is connected to the pen section of the character code. This connection method not only has poor display effect, but also the character code is easily damaged, shortening the character code service life
