Background technology
EPD (electronicpaperdisplay) display screen a kind ofly utilizes electrophoretic display technology and the display screen made.Existing EPD display screen, is mainly divided into two kinds:
The first is dot matrix display, and to show numeral, word, the graph image of change, during lastest imformation, need whole display frame refresh all, technology is comparatively complicated, and cost is higher;
The second is segment encode display, and to show fixing word and the numeral of change, display technique is comparatively simple, and be only suitable for the place not needing to show complex contents, this is also a large drawback in display field.
Summary of the invention
For prior art, the applicant is through Improvement, the EPD display screen of a kind of dot matrix and segment encode 2-in-1 1 is provided, utilizes drive IC to realize same screen point matrix and 2-in-1 1 display of segment encode, make full use of drive IC fan-out capability and help user to upgrade the appointed information of display screen.User can distinguish refresh point matrix part and segment encode part, also can dot matrix part and segment encode part refresh simultaneously.
Technical scheme of the present invention is as follows:
An EPD display screen for dot matrix and segment encode 2-in-1 1, comprises FPC flexible circuit board, drive IC, dot matrix part, segment encode part, STN glass substrate or alkali-free glass substrate, FPL Electronic Paper ink film and PS waterproof membrane; FPL Electronic Paper ink film, PS waterproof membrane is set gradually above STN glass substrate or alkali-free glass substrate, set-point matrix part, segment encode part above PS waterproof membrane, STN glass substrate or alkali-free glass substrate arrange FPC flexible circuit board, drive IC, FPC flexible circuit board connects development board, drive IC drive point matrix part, segment encode part.
Further, described drive IC is driven by Source and Gate driving forms, there is Source pin and Gate pin, a part of Source pin of described drive IC and a part of Gate pin provide output signal for described dot matrix part, and remaining Source pin provides output signal for described segment encode part.
Further, described dot matrix part is driven by the Source in described drive IC and Gate drives the connecting line of drawing to form pixel one by one, is used for showing the numeral, word, the Figure and Image that change.
Further, described segment encode part drives the connecting line of drawing to form Seg one by one by the Source in described drive IC, is used for showing fixing word and the numeral of change.
Advantageous Effects of the present invention is:
The present invention utilizes 1 drive IC to realize the EPD display screen of dot matrix and segment encode 2-in-1 1.
1, STN glass substrate can be used to replace the original TFT glass substrate used to realize the function of dot matrix and segment encode 2-in-1 1.The present invention adopts STN glass substrate or alkali-free glass substrate, on STN production line manufacturing function and TFT substrate glassy phase with STN glass substrate or alkali-free glass substrate, can reduce production cost greatly, and STN glass substrate is lower than alkali-free glass substrate cost.
2, realize dot matrix and segment encode 2-in-1 1, better embody the practical use of EPD display screen, raise the efficiency.
3, make full use of the fan-out capability of drive IC, help user to upgrade the appointed information of display screen.User can distinguish refresh point matrix part and segment encode part, also can dot matrix part and segment encode part refresh simultaneously.
4, owing to can dot matrix and segment encode separately drive, in practical application, drive current is compared original less, thus greatly reduces power consumption, extends the battery life of EPD display screen and shortens refresh time, simple to operate, convenient and swift.
