Description

Electronic paper button and mobile terminal with the button

technical field

The utility model relates to an electronic paper key and a mobile terminal with the key.

Background technique

Electronic paper is an "electronic matrix" display device. It has the following advantages:

1. Ultra-thin: Japan Epson has developed a 2.1-inch electronic paper with a thickness of 0.096mm;

2. Power saving: only when the screen changes, it will consume power;

3. Foldable: E-paper has the characteristic of being bendable and foldable. PHILIPS has exhibited a rollable e-book, and Seiko Watch has also exhibited a bendable e-paper watch;

4. Good contrast: no backlight is needed, and it can be read under strong light.

At present, electronic paper products are widely used, such as electronic books of Sony Corporation and Philips Corporation, electronic paper watches of Seiko Corporation, etc. In these fields, electronic paper is mainly used as a substitute for LCD screens, that is, as a display device.

At present, there is no product that uses the characteristics of electronic paper that can be displayed and bent as a key cap. The keys of mobile phones and other products on the market use silica gel, P+R (plastic key cap, silicone bottom plate) or P+R+TPU. (Thermoplastic polyurethane, thermoplastic polyurethane) These three types, these keys require the gap between the upper and lower rubber shells of the keyboard and the PCB (Printed Circuit Board, printed circuit board) board to be ≥0.8mm, plus the height of the keycap, the height of the entire key More than 1.8mm, relatively thick.

In recent years, due to the pursuit of ultra-thinness, steel sheet keycaps are popular in the mobile phone industry, that is, to achieve elastic deformation of the steel sheet by slotting in the middle, such as Motorola's V3 mobile phone. After that, there have been buttons that use a slot in the middle of a plastic film (PC (polycarbonate) or PMMA (plexiglass, commonly known as acrylic) or a mixed material) as a keycap. Later, there was a method of using a more elastic plastic film without slots in the middle to make the button structure more concise, but it was impossible to realize the function of the mobile terminal to perform multiple displays in multiple modes.

With the development of science and technology, current mobile terminals, especially mobile phones, have more and more functions. The increase of functions requires the use of more buttons, and the mobile terminal has the requirement of ultra-thin and portable, so it can be switched through the control module in different functional states, so as not to increase the number of buttons, and realize the effect of switching and displaying various buttons .

The technical solution disclosed in Chinese utility model patent 200620133117.8 achieves this function by dividing the light guide plate and grouping backlighting in different areas, but the disadvantages of this structure are: 1) Due to the thicker light guide plate, the overall thickness is relatively large ; 2) Since the display of the key utilizes processes such as silk screen printing or laser engraving on the keycap, the displayed content is limited.

The technical solution disclosed in Chinese utility model patent 200510086597.7 is to use EL (electroluminescent) film as the backlight, capacitive sensing chip as the key input device, through the division of the EL film, to realize different time backlighting in different areas, so as to realize different key display . The disadvantages of this structure are: 1) Since its display uses silk screen or radium engraving on the keycap, the display content is limited; 2) It feels poor, similar to a touch screen; 3) Because the EL film requires a higher voltage (200-300V) AC excitation, so it will affect the radio frequency index of the mobile terminal.

Detailed ways

Referring to Fig. 1 and Fig. 2, the electronic paper button of the present invention includes five parts, which are arranged in sequence from top to bottom: wear-resistant layer 1, electronic paper 2, substrate 3, metal arch film 4, and keyboard plate 5.

The wear-resistant layer 1 is used to improve the durability of the keys of the electronic paper. When the wear resistance of the electronic paper is high enough, the wear-resistant layer 1 can be omitted. The anti-wear layer 1 is a transparent or translucent plastic film, which has the characteristics of anti-wear, pressure resistance and elastic deformation. PC-PMMA composite film or other plastic films can be selected. Printing text or patterns can be carried out on the surface of the wear-resistant layer 1, such as silk screen printing, pad printing, electroplating, evaporation, IML (In-Mould Labelling, a type of in-mold labeling, in-mold transfer printing), IMD ( In Mold Decoration, in-mold decoration, a type of in-mold transfer printing), water transfer printing, etc., to achieve different visual effects.

The electronic paper 2 is used as the keycap of the button, which is ultra-thin and elastically deformable, and can display text and patterns at the same time. When it is necessary to switch between different usage states, the control module changes the display of the electronic paper keycaps through the user's input, so as to achieve the purpose of human-computer interaction. Electrical signals are transmitted through commonly used connection means, such as FPC (flexible printed circuit board) and so on.

The substrate 3 is a plate with small holes left at the position of the metal arch membrane 4 , and its thickness and aperture are determined by the size of the metal arch membrane 4 . The thickness of the plate is close to the size that the metal arch film 4 is higher than the keyboard plate 5, and the hole diameter of the plate is larger than the diameter of the metal arch film 4 so that it can pass through.

The keyboard board 5 is a circuit board carrying the metal arch film 4, which can be used alone or connected with the main board.

The above five parts are bonded together to form an electronic paper button.

The electronic paper button can be controlled to display different contents through the control module, and can also be used as a display device.

The above-mentioned electronic paper buttons can replace traditional buttons and be applied to mobile terminals, such as mobile phones. As shown in FIGS. 3 a to 3 e , the mobile phone using electronic paper buttons includes a housing, a screen, an antenna, a built-in chip, and electronic paper buttons.

It can be seen from the above drawings that the front of the mobile phone is very simple in the standby or off state. And when it is turned on and switches its working state, it can be in three working states: mobile phone state, music playing state and e-book reading state, and the corresponding electronic paper buttons also have different displays. When in the e-book reading state, part of the e-paper will be used as a display, which is power-saving (only consumes power when switching) and healthy (the contrast is similar to that of a newspaper, which can protect the eyes and relieve fatigue).

Another embodiment is to extend the anti-wear layer 1 and the electronic paper 2 to the position of the display screen, so that the electronic paper 2 can be used as a screen at the same time, as shown in Fig. 4a to Fig. 4e.

In the above-mentioned Figures 3a-3e and Figures 4a-4e, 31 represents the lens used to protect the screen, 32 represents the ordinary LCD screen, 4 represents the metal arch film, 34 represents the electronic paper button, and 35 represents the display of some text or For the electronic paper after the pattern, 36 represents the part of the electronic paper used as a display, and 37 represents the part of the electronic paper used as a screen.
