Description

Novel electronic ink screen keyboard special for education

Technical Field

The utility model relates to the technical field of electronic equipment, in particular to a novel electronic ink screen keyboard special for education.

Background

First, classification of keyboards

Currently, a general desktop keyboard is classified according to the number of key strokes, the key operation principle, the shape of the keyboard, and the like.

The number of keys of the key pad can be classified into 86 key pad, 101 key pad, 104 key pad.

1) 86 key keyboard: is the earliest keyboard and is characterized by no numeric keyboard region.

2) 101 key keyboard: the common keys and the numeric keys are separated and combined into a third area of the keyboard, namely a numeric keypad area.

3) 104 key keyboard: after Win95 is pushed out, three function keys are added, which is currently the most popular keyboard. The 104-key keyboard is a standard keyboard, is also a key number of a common keyboard, and can be mainly divided into a main keyboard area with middle letters, a functional key area above the keyboard, a numeric key area on the rightmost side, an editing area positioned in the middle of a typing keyboard area and a small keyboard, and the like.

The interfaces of the keyboard are classified into PS/2 interfaces, AT interfaces and USB interfaces according to different interfaces.

1) Desktop computers mostly adopt PS/2 interfaces, and most mainboards provide PS/2 keyboard interfaces. While older motherboards often provide an AT interface, also known as "big-mouth," it has not been common.

2) USB has become the most commonly used model at present, and application peripheral systems such as USB keyboards can be connected to a personal computer using the same standard. So the PS/2 interface has been slowly replaced by USB, a few desktop computers still provide a complete PS/2 keyboard and mouse interface, a few machines have no PS/2, and most machines only provide a set of PS/2 that the keyboard and mouse can share or only be used with the keyboard. Some mice and keyboards can use a converter to convert the interface from USB to PS/2, and also have a patch cord that can be tapped from USB to PS/2 interface for keyboard and mouse.

The keyboard can be classified according to the working principle into a mechanical keyboard, a plastic film type keyboard, a conductive rubber type keyboard and a contactless electrostatic capacitance keyboard.

1) The Mechanical keyboard (Mechanical) adopts a similar metal contact switch, and the working principle is to conduct or break the contact, so that the Mechanical keyboard has the characteristics of simple process, high noise, easy maintenance, strong rhythm sense during typing, no change of hand feeling after long-term use and the like.

2) The inside of the plastic film keyboard (Membrane) is divided into four layers, and the inside of the keyboard is composed of three layers of conductive films (the upper layer and the lower layer are both provided with circuits, and the middle is provided with an insulating layer) except the panel, so that no mechanical abrasion is realized, which is the key of the keyboard to trigger actions. Some panels use rubber caps and others use mechanical modules.

The film keyboard has the advantages of low price, low noise, low cost, simple process, good hand feeling and the like, and occupies most markets, but the hand feeling can be changed due to the material problem after long-term use. The keyboards used in our daily life are basically all thin film keyboards, and besides the upper and lower covers and the key caps of the keyboards which can be directly contacted, the silica gel caps, the thin film circuits and the circuit boards below the keys can be seen.

3) The structure of the conductive rubber keyboard (conductive rubber) contact is connected through conductive rubber. A layer of conductive rubber with charged bulges is arranged in the keyboard, each key corresponds to one bulge, and the lower contact is connected when the key is pressed down. This type of keyboard is a product of the market transition from a mechanical keyboard to a membrane keyboard.

4) Contactless electrostatic capacitive keyboards (capacitive) use a capacitive-like switch to drive the encoder by changing the distance between the electrodes when pressed to cause a change in capacitance. The sealing device has the characteristics of no abrasion and good sealing performance.

The shapes of the keyboards are classified into standard keyboards and ergonomic keyboards according to the shapes.

1) Standard keyboards are rectangular keyboards that we most commonly see in everyday use.

2) The human engineering Keyboard is characterized in that a standard Keyboard is provided with a left-hand keypad and a right-hand keypad which are specified by fingering, which are separated left and right, and form a certain angle, so that an operator does not need to consciously clamp two arms, and a Natural form is kept. Some ergonomic keyboards also enlarge the area of common keys such as space keys and carriage return keys, and a hand guard support plate is added at the lower part of the keyboard, so that the wrist is suspended for supporting points in the past, and fatigue caused by long-term suspension of the wrist is reduced. These can be considered as humanized designs.

The human engineering keyboard is characterized in that a common keyboard is divided into two parts and unfolded at a certain angle, and the keys of the keyboard are positioned at a comfortable angle for a user to adapt to the angle of hands, so that an operator does not need to bend wrists. Therefore, the hands and the wrists of the user are relaxed and are in a natural state, so that the fatigue of the wrists can be effectively reduced, and the strain of the muscles of the wrists can be effectively relieved. From the perspective of ergonomics, a person who performs keyboard operation for a long time can use an ergonomic keyboard to improve the operation efficiency and operate for a long time, and an operator can adopt a comfortable and natural operation posture, so that the problem of physical fatigue caused by the fact that the operator adopts an abnormal posture due to the existing keyboard operation condition is solved. This can be prevented.

Whether mechanical or capacitive keyboards, or from the early 83-key keyboards to the so-called standard keyboard 104-key keyboards, the application is mainly dependent on hardware CPU and software operating systems. The following describes the problems of the construction and the working principle of the keyboard.

(II) keyboard structure

The PS/2 device implements a bi-directional synchronous serial protocol. In other words, one bit of data is sent on each data line and one pulse is read in on each clock line. The device may send data to the host and the host may send data to the device, but the host always has priority on the bus, which may inhibit communication from the device at any time, simply by pulling the clock line level low.

The internal structure of the keyboard mainly comprises a control circuit board, keys, a bottom plate, a panel and the like. The circuit board is a control core of the whole keyboard, is positioned in the keyboard and mainly serves as a key scanning identification, coding and transmission interface for work; it converts the numbers or letters represented by the keys into signals recognizable by the computer, which is one of the main communicators between the user and the computer.

The keyboard mainly comprises a key switch matrix, a singlechip and a decoder. The key switch matrix, that is, the keyboard keys, are composed of a group of key switches arranged in a matrix manner, and the input signals are determined by the positions of the keys. The Intel8048 single-chip microcomputer microprocessor adopted in the single-chip microcomputer, namely a 40-pin chip, integrates an 8-bit CPU, a 1024×8-bit ROM, a 64×8-bit RAM, an 8-bit timer/counter and the like. The decoder is a signal code translation device, which converts the character signal of the keyboard into corresponding binary code through code translation. Because the keyboard is arranged into a matrix format, the identification of the keys and the generation of the row and column position scanning codes are realized by a singlechip in the keyboard through a decoder.

(III) principle of operation

Computer keyboards typically employ a line scan method to determine the line location where a key is pressed. The row-column scanning method is to arrange keys of a keyboard into an n x m row-column lattice, connect row lines and column lines to two connecting lines for bi-directional transmission of two parallel interfaces, and when a key on the lattice is pressed, the row-column lattice signal of the key is considered to be turned on. The matrix formed by the keys needs to scan the rows and columns of the matrix sequentially by a hardware or software method to inquire and confirm whether the keys are pressed. If a key is pressed, the keyboard sends a position code of a row-column lattice where the key is located to the host, which is called a key scanning code. The singlechip reads back scanning signal results through periodically scanning the row and column lines, judges whether a key is pressed down, and calculates the position of the key to obtain a scanning code. When the key is pressed, the singlechip transmits the position scanning code to the keyboard interface twice: pressing once, and switching on the scanning code; after the release is finished, the scanning code is disconnected. Thus, the keyboard is scanned by hardware or software to determine the position of the pressed key, obtain and output the scanning position code, and then converted into ASCII code, which is sent to the host computer via the keyboard I/O circuit and displayed by the display.

It is easy for a keyboard to increase the number of keys, and any matrix keyboard can achieve an increase in the number of keys by increasing the number of rows or columns of the keyboard. For example, a 64-key keyboard is arranged in an 8-row by 8-column matrix, a 128-key keyboard is arranged in an 8-row by 16-column matrix, and a 256-key keyboard is arranged in a 16-row by 16-column matrix, which has been described in the publication of microprocessor-based design, 7 in 1992 (this comparison was submitted on 12/13/2001). Therefore, it has long been a common technology to use a matrix type keyboard structure.

(IV), screen display principle

Any screen is composed of individual pixels. The final display effect of the screen, whether it be an LCD, OLED or ink screen, is the combined effect of its individual pixels as a whole, so whatever data is transferred is dotted on the screen. By controlling the color of the pixel points, different colors are displayed. The displayed data is obtained by taking a module, and the data is sent to a screen and then displayed.

Display mode of ink screen

The display principle of the ink screen is different from that of other screens. OLEDs are self-luminescent materials and the entire screen is made up of individual transistors that can be individually lit. And LCD screens require a backlight panel to display the content. The ink screen itself is not lighted, but rather is displayed by reflection of ambient light. It consumes little power when displayed normally, and only during the refresh display. Therefore, the display effect is equivalent to that of paper books, and compared with other screens, the display effect is eye-protecting.

When the screen is electrified, the ink with different voltages runs on the screen, the black ink runs on the screen, and the white ink runs on the screen under the action of the voltages with different polarities.

Fifth, touch pad principle

Touch pad products in the current market mainly comprise two technologies, one based on a capacitance principle and the other based on a resistance principle. The touch control plate of the capacitance principle is formed by a deformable resistance film and a fixed resistance film, the middle is isolated by air, when a finger contacts the touch control plate, the upper resistance is pressurized to deform and contact with the lower resistance, and the lower resistance film can sense the position of the finger, so that the movement of the cursor is controlled.

Most of the existing keyboards in schools are different from the keyboards in the market, but the sizes of hands of teenagers and adults are different from each other, the use habits of the teenagers and the adults are different, and most of the key caps of the keyboards adopt fixed key patterns and cannot exert imagination of students; therefore, designing a new keyboard dedicated for education is a technical problem that needs to be solved by those skilled in the art.
