Abstract
The utility model discloses a portable electronic reader with dual TFT-LCD liquid crystal display screens. The dual TFT-LCD liquid crystal display screens comprise a main liquid crystal display screen and an auxiliary liquid crystal display screen, the main liquid crystal display screen is integrated with a shell body into a whole, and the auxiliary liquid crystal display screen is arranged in a protective cover, can be combined with and separate from a host. An ARM series microprocessor (MPU) is used. The portable electronic reader can be used as the reader of publications such as electronic books, newspapers, magazines and so on, and can be used as an electronic bag in school to substitute paper books and notebooks to form non-paper learning.
Description
Affiliated technical field
The utility model relates to a kind of double T FT LCD (Thin-Film Transistor Liquid-Crystal Display) LCDs portable electronic reader.The reader that can be used as the publications such as book, newspaper, magazine of electronic edition, and can be used as e-schoolbag in school and use, learn to substitute paper book, basis, to form with no paper at all.
Background technology
1. the student uses paper book, basis and learning materials at present.The school bag of book of packing into the ten or twenty jin that weighs is gone to school and left school to the student and have been brought great burden, and part student's health comes to harm.Part student is unable to bear it on the back heavy school bag and goes to school and leaves school, and has become in tow the school bag of belt wheel and has gone to school and left school.
2. the book of papery, basis, a large amount of timber of newpapers and periodicals consumption.And the pollution that when system paper, produces water and air.
3. reader, the e-schoolbag of developing at present mostly is the monochromatic and STN chromatic liquid crystal screen of single screen.One of its shortcoming is that demonstration achromatization or color are not true to nature.Another kind of is to use as e-schoolbag with notebook computer.Its shortcoming is to press close to teaching and price comparison height preferably.
4. existing papery textbook is noiseless teaching material.Figure, literary composition, sound and luxuriant teaching material can further improve results of learning.
Summary of the invention
For above problem, the utility model provides a kind of double-display screen reader, this reader promptly can be used for reading electronic edition books, publication, also can be used for school student, the alternative paper book of teacher, basis, also can be used as network terminal browsing page, the downloaded data of the Internet.Apolegamy wireless receiving module or radio receiving transmitting module can also be realized wireless mode exchange electronic information and data.
The technical scheme that its technical matters that solves the utility model adopts is: reader comprises main frame and over cap.Can adorn the secondary Thin Film Transistor-LCD TFT-LCD (Thin-Film Transistor Liquid-Crystal Display) of a slice in the over cap.Secondary LCDs also can be placed apart with main frame.A slice master Thin Film Transistor-LCD TFT-LCD (Thin-Film Transistor Liquid-Crystal Display), printed circuit board (PCB), rechargeable battery, resistance-type electronic orbit plate, SD deck, Ethernet interface, USB interface, function button, power switch, power circuit, radio receiving transmitting module circuit are housed in the host housing.ARM series microprocessor MPU (as S3C2440 or S3C2410 or S3C6400) integrated circuit, SDRAM/Flash ROM memory integrated circuit (as K4S561632, K9F1208, SST39VF160/320 series) are housed on the circuit board, functional integrated circuits such as audio frequency (UDA1341), serial ports controller (MAX3232), ethernet controller integrated circuit CS8900A also are housed.
The beneficial effects of the utility model are,
1. use the high-quality display screen, can show high-quality, coloury photo information.
2. use the high speed 32-bit microprocessor, improved computing, processing speed.
3. use the microprocessor and the peripheral integrated circuit of low-power consumption, can prolong the service time of battery.
4. substitute paper book, basis in the electronics mode, reduce the raw materials consumption of paper, the pollution of system paper.
5. adopt WINDOWS CE or LINUX operating system, conveniently use existing all kinds of softwares, can enrich the functions of use of reader.The new software of also convenient exploitation is realized new function.
6. use double screen to show, can enlarge the display area of data, books, newpapers and periodicals, meet the custom of paper book.
7. the removable screen of paying separately, when not needing to pay screen, Dan Ping carries to alleviate and carries weight.
8. adopt NAND Flash ROM data on file, in the time of can avoiding using the magnetic medium data on file to meet high-intensity magnetic field, the losing of the irrecoverable property of data.
9. adopt wireless receiving circuit module or radio receiving transmitting module, can conveniently receive exchange message with wireless mode.Below in conjunction with drawings and Examples the utility model is further specified.
