Abstract
The invention discloses an intelligent card which comprises a flexible printed circuit board, an electronic paper display, a flexible gate driver, a flexible source driver and an integrated circuit. The electronic paper display is arranged on the flexible printed circuit board. The flexible gate driver and the flexible source driver comprise thin-film field-effect transistors and are arranged on the electronic paper display. The integrated circuit is arranged on the flexible printed circuit board and is used for supplying control signals for the gate driver and the source driver. The intelligent card has the advantages that the flexible gate driver and the flexible source driver can be bent under constraints of bending angles without constraints of physical properties of silicon materials, in other words, damage the flexible gate driver and the flexible source driver due to excessive bending angles of the flexible gate driver and the flexible source driver can be prevented even if the flexible gate driver and the flexible source driver are lengthened, accordingly, the electronic paper display and the intelligent card can be large in size, and the application ranges of the electronic paper display and the intelligent card can be expanded.
Description
Technical field
The present invention is open a kind of smart card, espespecially a kind of bendable smart card.
Background technology
Smart card (smart card) can be described as again integrated circuit card (IC card), its can be by the integrated antenna package with storage, encryption and data-handling capacity in plastic sheet to be applied in every field, for example can use at identity IC-card and traffic ticket card etc.In addition, electric label is a kind of mobile device recognition device with radio communication function and information storage function.
The driving circuit of dot matrix type Electronic Paper (the dot-matrix electronic paper) display screen in smart card or electric label is to use silicon wafer material to make at present, and because if one of silicon wafer properties of materials exceedes the limit of its physical characteristics for the deformation that is subject to external force and causes, to cause silicon wafer to break and cause the driving circuit of silicon wafer material to damage, so the angle that can bend in the time using smart card or electric label is little and limited, may damage smart card or electric label once exceed the angle that can bend.That is to say that electronic-paper display screen and the driving circuit thereof in smart card or electric label can be considered two discrete assemblies at present, connect with winding displacement therebetween, thus, although electronic-paper display screen is bendable, be make and make it be difficult to bending with silicon wafer material but be limited to its driving circuit, the angle that overall smart card or electric label can be bent is limited.Also therefore the size of most smart card or electric label is not more than the size of credit card, so that it can be in some angle inner bending and be not impaired.But along with the increase of the electronic-paper display screen size in smart card or electric label, its driving circuit also needs to lengthen thereupon, and driving circuit after lengthening is because be subject to the restriction of silicon wafer physical characteristics of materials, make cannot to guarantee to have that the driving circuit of amplifying electronic-paper display screen can be bent and not impaired, and then limited the size that electronic-paper display screen and overall intelligence card or electric label can increase, also limit the range of application on smart card or electric label.
Summary of the invention
One embodiment of the invention discloses a kind of bendable smart card.This smart card comprises a flexible printed wiring board, an electronic-paper display screen, a bendable gate drivers, a bendable source electrode driver and an integrated circuit.This electronic-paper display screen, is arranged on this flexible printed wiring board.This bendable gate drivers is formed and be arranged on this electronic-paper display screen and be coupled to this electronic-paper display screen by Thin Film Transistor (TFT), in order to provide gate drive signal to this display screen.This bendable source electrode driver is formed and be arranged on this electronic-paper display screen and be coupled to this display screen by Thin Film Transistor (TFT), in order to provide source drive signal to this display screen.This integrated circuit is be arranged on this flexible printed wiring board and be coupled to this gate drivers and this source electrode driver, in order to provide control signal to this gate drivers and this source electrode driver.
The bendable gate drivers of the embodiment of the present invention, bendable source electrode driver and bendable latch all can be bent and can not be subject to the restriction of silicon wafer physical characteristics of materials and have the restriction of bending angle, even if that is to say that its length lengthening also can not damage because exceeding bending angle, so the size of the size of electronic-paper display screen and smart card itself can do more, with the scope of its application of augmentation.
