Abstract
The present invention relates to a flexible display device. It mainly includes flexible display, soft printed circuit board and its control circuit. Said control circuit includes microprocessor or simple control logic circuit, display drive circuit and battery. Said display is electrophoretic display (namely bistable display).
Description
Technical field
The present invention relates to a kind of display equipment, refer in particular to a kind of flexible display.Wherein display is an electronics swimming display, and it structure is contained on the flexible printed wiring board, one-tenth one flexible display body capable of being combined, and, can reach the purpose of demonstration by control circuit control.
Background technology
Because the progress of science and technology, display is by the cathode ray tube (CRT) display of previous massiveness, and being replaced by LCD (LCD) gradually is as products such as LCD TV, LCD monitor.And LCD is frivolous more many than cathode-ray tube (CRT), and the portable product of LCD also is developed, for example mobile computer (Notebook), personal digital aid (PDA) (PDA), mobile phone, accutron or the like.But because of LCD is to be base material (substrate) with glass, easily broken, therefore when product design, must be except that in mechanism strong especially with LCD, and need to strengthen its protective, therefore in lightening process, run into bottleneck.Especially in the new century, the application product of Wearable has become current main-stream, however the combination with it that present display equipment also can't be appropriate, and then satisfy the various demands of the society of scientific-technical progress now, the regret of lost pearl is arranged unavoidably.With the accutron is example, except watchband, the table heart that also need have the demonstration effect must hold circuit arrangement and power-supply system etc. in it, and visible on the market all is suitable heavy and bulky product, moreover its design variation is little, at most just seize on an incident to exaggerate or distort matters, make the simple change on some functions, but its outward appearance pattern still seems clumsy at the control IC of inner tool clocking capability, with the trend of stressing " compact " now, as if be difficult to ask again popular.Therefore, the expansionary of this series products promptly is subjected to suitable restriction, and is difficult to break through again.
Because cathode-ray tube display and LCD is thick and heavy and stiff, and the application target that lacks variation, and be difficult to incorporate the purpose purposes of the life-stylize except that electrical equipment or computer product, the inventor thinks a kind of characteristic of utilizing the moving display of electrophoresis, in conjunction with soft circuit printing plate, and invent out a kind of flexible display device, structure be can be easy to by it again and the crooked band shape or the characteristic of strip article dressed up, thereby it is easy and banded, strip or flexibility, the various articles required combination of soft life-stylize, make the more frivolous and tool portability of these article, and reach the effect of certain demonstration and the effect of decoration, and therefore overcome the shortcoming that cathode-ray tube display and LCD can't combine with soft article.
Summary of the invention
Fundamental purpose of the present invention, promptly providing a kind of display equipment, refer in particular to a kind of flexible display (Flexible Display Panel), mainly be to utilize a kind of electrophoresis to move display (ElectrophoreticDisplay), be bistable display (Bistable Display), its structure is contained on the flexible printed wiring board, be combined into the flexible display body, and, can reach the purpose of demonstration by control circuit control; Structure be can be easy to by it again and the crooked band shape or the characteristic of strip article dressed up, thereby easily combine with the various articles required of band shape, strip or flexibility, soft life-stylize, more frivolous and the tool portability of these article be can make, and the effect of certain demonstration and the effect of decoration reached.
The present invention is combined into body (1) by moving display of electrophoresis and flexible printed wiring board, adds control circuit again, and forms device of the present invention; Wherein electrophoresis moves the structure of display and flexible printed wiring board, as shown in Figure 1, its surface is made of layer of transparent soft plastic material (PET) (11), in its bottom surface is one deck plates tool electric conductivity with plating mode indium oxide (ITO) (12), it is the moving display material (13) of electrophoresis down, and the bottom then is a flexible printed wiring board (14).Externally then be provided with the control circuit (2) (as shown in Figure 2) that display drives in addition, be connected with the flexible printed wiring board (14) of bottom; This control circuit wherein, be provided with microprocessor (Micro-Controller) (21) or simple control logic circuit (211) (as shown in Figure 3), circuit of display driving (Display Driver) (22) and battery (23), provide required electric power (battery is replaceable) by battery, and control the indium oxide (12) and flexible printed wiring board (14) electrode of tool electric conductivity whereby, make the electrode voltage between two base materials produce positive and negative pressure, and then make electrophoresis move display material (13) to change its color according to the variation of voltage, to reach the purpose of demonstration.
In the structure of moving display of above-mentioned electrophoresis and flexible printed wiring board, wherein the thickness of transparent soft plastic material (11) is in 0.15 millimeter (mm), and the thickness of the indium oxide of electrodeposited coating (12) is extremely meagre, almost can ignore, in the display material (13) then about 25 microns (micro meter), the thickness of flexible printed wiring board (14) can be in 0.1 millimeter, so its result can produce and is lower than 0.26 millimeter with interior flexible display.
Utilize flexible display device of the present invention, because of its easy structure is dressed up crooked product, so it is applied in ultra-thin product, especially the various articles required with banded, strip or flexibility, soft life-stylize combine, more frivolous and the tool portability of these article be can make, and the effect of certain demonstration and the effect of decoration reached.And wherein the shown pattern content (pattern, literal, numeral etc.) of flexible display is to produce on the flexible printed wiring board by designing and being stored in, it can be according to different application purposes or purposes, change the pattern content on the flexible printed wiring board, and make the present invention have more variability, thereby improve to use when application product, more get consumer reception and favor.
Moreover, for making the present invention bring into play better effect, can have the function or the effect of noctilucence or flicker as the pattern that shows, as long as in body of the present invention, add Noctilucent device, and be connected with control circuit, can produce the effect of noctilucence, or add the design of flashing function in control circuit, then can produce the effect of flicker, also can control the time or the mode of flicker certainly by the design of control circuit.In addition, also can make the present invention have the function of demonstration time, temperature or the like,, and be connected with control circuit and to get final product as long as add crystal oscillator or temperature inductor.Therefore but the present invention range of application as can be known is extensive, is to pass through the combination of interfacing equipment or device, and reaches the effect of different demands.Moreover, for making the present invention have more effect attractive in appearance or that tool is decorated, also can other decorative article fit or thereon bonding, perhaps the present invention is placed or fit on certain decorative article or other various articles required, and reach effect practical more, attractive in appearance or that tool is decorated, thereby attract consumer's favor.
