LCD Liquid Crystal Display Introduction

1、Definition

LCD is the abbreviation of Liquid Crystal Display. The structure of LCD is a liquid crystal placed in the middle of two pieces of parallel glass, and there are many tiny vertical and horizontal wires in the middle of the two pieces of glass, which control the direction of the rod-shaped crystal molecules by energizing or not, and refract the light to produce a picture. Liquid crystals are organic complexes composed of long rod-like molecules. In their natural state, the long axes of these rod-shaped molecules are roughly parallel.

2、Working principle　When the glass substrate does not join the electric field, light through the polarizing plate followed by liquid crystal to do 90 degrees twist, through the polarizing plate below, the LCD panel shows white; when the glass substrate to join the electric field, liquid crystal molecules produce alignment changes, light through the liquid crystal molecules gap to maintain the original direction, by the polarizing plate below, the light is absorbed can not be transmitted, LCD LCD is based on the presence or absence of this voltage, so that the panel to achieve the display The effect is based on the presence or absence of this voltage.

Monochrome LCD screen

By choosing the right custom LCD solution, you can make your product look different and have an aesthetically pleasing and brighter display. Wafer Works has a complete line of black and white LCDs that can be customized to include TN, STN, FSTN, DFSTN, ASTN, ISTN and Bi-Stable LCDs. Our design and development team can work with your development needs to design the most suitable display solution.

TN LCD is generally a pen type or character type display and is the lowest cost LCD type. With ITO coating line, black and white LCD production line, fully automatic pin-up line, fully automatic screen printing line and fully automatic cutting line, Huaxin Technology has the characteristics of high output and high efficiency. Since its development, Wafer Works has become the world's leading supplier of black and white display solutions, selling over one million products daily to all over the world.?

TN STN LCD has a wider viewing angle than TN LCD, and can also do dot matrix type in addition to pen type and character type display.

STN LCD has a wider viewing angle than TN LCD and can be used in addition to stroke-type and character-type displays, and STN LCD can be used with semi-transmissive or reflective polarizers for direct display without backlighting, reducing the power consumption of the finished product. Moreover, LCD can also be embedded with simple touch function, combining display and touch function into one, which is a good alternative to physical button panel.? ?

VA (Vertical Alignment (VA screen))

Different colors of backlight can be used to achieve different color display effects(Vertical Alignment) black and white display has high contrast ratio and the background color can be changed according to the backlight color. VA's high contrast ratio provides the sharpest display of any black and white display type. Thanks to our fully automated screen-printing equipment, Waxchip can provide VA products with different color patterns. The VA we offer can also be embedded with touch functions instead of simple touch presses New Item

COG (Chip-On-Glass) Displays

COG Displays achieve the multiple advantages of thinner thickness, lighter weight, and better cost by binding the integrated chip IC directly to the glass surface process, compared to binding the IC to the PCB. Our product line covers various COG specifications, from simple 08*01 field display to high resolution 320*240 matrix display, with various colors of backlight and customized iron frame to meet customers' various needs.

COB (Chip on Board)

COB display is a traditional process of displaying by integrating chip IC bound on PCB, which can work properly in harsh operating environment due to the rugged and reliable quality of PCB. Therefore, COB display is suitable for products with wide temperature application environment or high shock resistance requirement.

TAB (Tape Automated Bonding) & COF ( Chip on Film)

TAB is a type of display that uses the IC process of tape on board packaging and is suitable for product applications that require high space utilization and easy installation due to its unique advantages

.

Graphic LCD (Graphic Screen)

Wafer Works offers graphic LCD modules (plotted LCD modules) in SMT, COB, TAB and COG processes. Our graphic dot matrix LCD modules all use STN technology to ensure high contrast ratio and wide viewing angle. The display modes are mainly STN yellow-green and blue modes and FSTN gray mode, and the operating temperature is from -20 to 70 degrees Celsius, and also from -40 to 70 degrees Celsius. Our LCD modules can be used in many fields, such as instrumentation, industrial control, electric power, environmental protection and new energy industries

.

Character LCD(Character Screen)

Huaxin Technology provides a series of standard character LCD modules with specifications from 8x2 to 40x4, which can display ASCII codes such as numbers and letters, with operating temperatures from -20 degrees to +70 degrees, and interface methods such as 8-bit parallel and serial ports. These character LCD modules can be used in industrial equipment, instrumentation, communication equipment and embedded systems, etc

.

microtherm LCD Module(Low Temperature Display Module)

Huaxin Technology has designed and developed three kinds of low-temperature display modules for severe cold regions and military industries. The first one is low temperature LCD module, usually the working temperature can reach minus 20 to minus 30 degrees, and the liquid crystal material can reach minus 40 degrees after special treatment or module heating; the second one is low temperature OLED module, the working temperature can reach minus 40 degrees; the third one is high reliability display module, the working temperature can reach minus 40 degrees, and the storage temperature can reach -55 degrees

.

Serial port LCD (serial port display module)

Serial port display module includes serial port LCD module, serial port OLED module and serial port TFT module. Serial port mode includes SPI, I2C, UART, USB, RS232 and RS485, etc. The new generation of serial display developed by Huaxin Technology contains powerful MCU and very customer-friendly software, which makes the display module intelligent.

OLED (Organic Light-Emitting Diode)

OLED display has high brightness and contrast, very fast response time, high color saturation and low power consumption, these advantages make OLED suitable for any industry and application. Our OLED viewing angles are greater than 160 degrees in any direction and can be used in temperatures as wide as -40 to +80 degrees Celsius. All products have built-in controllers and are RoHS compliant, with optional interfaces such as parallel, SPI, I2C, UART, USB, RS232 and RS485

.

TFT (Thin Film Transistor)

TTFT LCDs are thin film field effect transistors. The so-called thin film transistor means that each pixel point of the liquid crystal display is driven by a thin film transistor integrated in the back. This allows for high speed, high brightness, high contrast LCD screen information. TFT belongs to the active matrix LCD.

TFT LCD display high display quality, large viewing area, digital interface, thin and compact, low power consumption, wide range of applications; from -20 ℃ to +50 ℃ temperature range can be used normally, after the temperature reinforced processing of TFT-LCD low temperature working temperature can reach -80 ℃.
