Dot matrix and segment code two-in-one EPD display screen

Abstract

The invention discloses a dot matrix and segment code two-in-one EPD display screen. A dot matrix portion and a segment code portion are driven by a driver IC, the driver IC comprises a Source driver and a Gate driver, output signals are provided by partial Source pins and partial Gate pins of the driver IC for the dot matrix portion, output signals are provided by the other Source pins for the segment code portion, for the dot matrix portion, connection wires led out by the Source driver and the Gate driver of the driver IC form multiple pixel points, the pixel points are used for displaying changeable digit, character and graph image information, for the segment code portion, connection wires led out by the Source driver of the driver IC form multiple Segs, and the multiple Segs are used for displaying fixed characters and changeable digits. Through the dot matrix and segment code two-in-one EPD display screen, dot matrix and segment code two-in-one display can be realized on one same screen, the dot matrix portion and the segment code portion can be respectively refreshed, the dot matrix portion and the segment code portion can be simultaneously refreshed further, and the dot matrix and segment code two-in-one EPD display screen further has advantages of small refreshing current, low power consumption, simple operation and convenience and rapidness.

Description

technical field [0001] The invention belongs to the field of electronic paper display, and is an EPD display screen capable of realizing 2-in-1 display of dot matrix and segment code on the same screen. Background technique [0002] EPD (electronic paper display) display is a display made using electrophoretic display technology. The existing EPD displays are mainly divided into two types: [0003] The first is dot matrix display, which mainly displays changing numbers, text, and graphic images. When updating information, the entire display screen needs to be refreshed, which is more complicated in technology and higher in cost; [0004] The second type is segment code display, which mainly displays fixed text and changing numbers. The display technology is relatively simple, and it is only suitable for places that do not need to display complicated content. This is also a major drawback in the display field. Contents of the invention [0005] Aiming at the existing tech...
