Abstract
The utility model relates to a display screen for portable electronic equipment, which is an electronic ink (E-ink) display device which is connected to a circuit of the original electronic equipment. The display screen has total reflection, and does not need back light module sets; the utility model consumes power only at the time of picture conversion. The display contrast and illumination of the utility model is free from the adverse influences of luminous environment (indoor and outdoor) and viewing angles (a visual angle is close to 180 DEG). In general, the display screen which uses electronic ink as a display interface has the advantages of low cost, less power consumption and clear display; meanwhile, the utility model is convenient to view information display.
Description
Technical field
The utility model relates to information display technology, specifically is a kind of display screen of realizing portable electric appts information, and this display screen uses electric ink (E-ink) as display interface, and cost is low, and little power consumption is convenient to watch.
Background technology
Portable electric appts such as existing mobile phone generally select for use LCD or OLED as display screen.All there is the blind area in these two kinds of display screens, such as, common LCD or OLED are difficult to see clearly Chu in the place of light direct projection; Perhaps, if the visual angle is not right, just can't see whatever; In addition, LCD need mix backlight can demonstrate information, and this has just additionally increased the demonstration cost; As for OLED, its defective is that the life-span is shorter.And the power consumption of these two kinds of screens of OLED and LCD is all very big, and battery is not long service time, needs frequent charge.
Summary of the invention
Emerging in recent years this display technique is exactly " electric ink (E-ink) ".Its display performance is good, use cost is cheap, and the purpose of this utility model just provides a kind of display screen that is used for portable electric appts, and this display screen utilization electric ink (E-ink) is as the display screen of portable electric appts.
Another purpose of the present utility model provides a kind of display screen that is used for portable electric appts, and this display screen uses electric ink as display interface, and cost is low, little power consumption, and clear display, the information of being convenient to shows watches.
The utility model is achieved in that
A kind of display screen that is used for portable electric appts is characterized in that this display screen is electric ink (E-ink) display, and this display is connected in the circuit of original electronic equipment.
The described display screen that is used for portable electric appts, the capsule of the titanium dioxide (white) of its electronegative carbon (black) and positively charged, cover on the film, constitute panel, the electrode that setting and capsule connect mutually below panel, form base plate, panel and base plate form this electronic ink display.
Above-mentioned display, its panel top also can be coated with transparent resin or plated film as protective seam, prevent that this display is subjected to the damage of external force.
Above-mentioned display, its base plate are the TFT base plate, also can adopt the base plate of other form.
The interface of described display and portable electric appts movement circuit can adopt serial line interface or parallel interface that electric ink (E-ink) display is attached to driving circuit, control circuit.
Connect the used lead of foregoing circuit, can use soft winding displacement, also can use conductive rubber.
Principle of work to electric ink (E-Ink) display mode is described as follows below:
In electric ink (E-Ink) display mode, use a kind of very small transparent resin capsule, this capsule contains the titanium dioxide (white) of electronegative carbon (black) and positively charged, this capsule is coated on the film, constitute panel, the electrode that setting and capsule connect mutually below panel, form base plate, form a complete display screen thus.Apply electric signal on its electrode, titanium dioxide and carbon will be moved up and down by the driving of electric field, demonstrate and the corresponding black of signal.
Titanium dioxide is the pure white powder, and carbon is the ater powder, and which type of writings and image is the result who forms through electric field driven need demonstrate, as long as apply corresponding signal on its electrode just as in black and white.This display is the view angle dependency as LCD not, and in case after writing content, even its content also can keep showing in outage, therefore the demonstration not power consumption basically of same width of cloth still image, just when image transitions, just understand power consumption, its power consumption is less than 1/10 of reflection type LCD, is ultralow power consumption.
Certainly, the ability of " Electronic Paper " outage maintenance information is strong unlike paper commonly used, As time goes on, displaying contents meeting " desalination ", if write this moment again, image can return to original state again.
The electrode aspect, use be the TFT base plate that often uses with liquid crystal etc.The thickness that adopts glass TFT base plate at present is about 0.9mm, if adopt the ultra-thin TFT base plate of plastics, its thickness can be littler.In fact manufacture experimently out the only display screen of 0.3mm of thickness now.If use the deformable base plate the same, can also produce folding display screen with plastics.
The outstanding feature of electric ink (E-ink) display is ultra-thin, and thin sensitive paper is the same, therefore is Electronic Paper again.Because it is thin, no matter under which type of lighting environment, no matter go from what angle, its contrast and brightness can not be affected, it does not only need backlight, and also not power consumption when keeping picture, reduce power consumption significantly, thereby allow to cut down battery capacity, prolong battery service time, reduce use cost greatly.
In sum, the utility model effect is:
1.E-ink display screen is total reflection, does not need module backlight, and consumed power just when the conversion picture only.Therefore adopt portable electric appts of the present utility model, the power consumption of its battery significantly reduces, and prolong the service time of battery greatly.
2. adopt portable electric appts of the present utility model, its contrast of display degree and brightness are not subjected to the adverse effect of lighting environment (indoor, open air), viewing angle (visual angle is near 180 degree).This be the OLED that generally adopts now and LCD display can not compare.
3. because the structure of E-ink display screen causes its panel can use printing technology to produce in enormous quantities, this will make the cost that adopts portable electric appts of the present utility model reduce, and what therefore become is inexpensive.
4. because the E-ink display screen is paper-thin, do not need backlight yet, adopt portable electric appts of the present utility model lighter, thinner, be more convenient for carrying what therefore become.
Description of drawings
The structural representation that Fig. 1 implements for the utility model,
Fig. 2 is the circuit diagram that the utility model is used as mobile phone display screen,
