TFT LCD TYPE

The main features of a TFT touch screen

TFT LCD, acronym for Thin Film Transistor Liquid Crystal Display, is a technology developed for improve image quality and has countless consumer and industrial uses.

Specifically, within TFT monitors, liquid crystals allow faster and smoother state transitions while saving power, resulting in high image quality on the display, which appears without flickering or bright irregularities (unlike simpler LCD screens).

TFT screens can be of different sizes, ranging from small 3.5" screens to large displays, and can also be identified by their area of use or by certain special features and applications, such as multitouch.

TFT displays are always clearly visible in sunlight, making them particularly suitable for outdoor use. This type of display is also particularly light, thin and energy-efficient, as well as being relatively inexpensive in relation to the technical features offered.

TOUCH SCREEN

Industrial touch screen monitors with capacitive and resistive technology

A touch-screen display is a type of screen that allows the user to interact with the operating system using their fingers, without having to use physical buttons. In industrial environments, a touch screen monitor is essential for direct operator interaction with systems and machines.

The main types of touch screens are the resistive touch screen and the capacitive touch screen.

Resistive touch monitors are the simplest and most economical technology, made from two layers of plastic covered with a conductive material and separated by an additional insulating layer. By exerting pressure, electrical contact is generated with the layer underneath, allowing the coordinates of the contact point to be plotted.

Capacitive touch screens are more modern and innovative, with an outer glass surface crossed by a uniform electric field that varies with the contact of the user's fingers. Importantly, thanks to this technology multi-touch is possible.

In the industrial field, the touch screens are widely used in various manufacturing sectors and in the packaging, logistics, motion control and industrial automation markets.

The Digimax range of customisable industrial touch screens

Compared to normal consumer touch screens, industrial touch screen monitors must have additional features based on the different industrial applications:

- Greater resistance to impact and wear in hostile environments such as workshops, factories and outdoor spaces;
- Variable sizes for specific needs: 5, 10, 15, 22 or 24 inch touch screen monitors...;
- Capacitive or resistive touch technologies, for use in wet environments or with glove recognition;
- Adjustable brightness for indoor or outdoor use, high brightness touch screen from 800 to 2000 candelas;
- Vandal-proof and screen-printed display and cover lens glasses;
- USB, I2c and RS-232 touch interface for connection to specific hardware.

The wide range of latest-generation capacitive touch screens and multi-touch monitors distributed by Digimax can be fully customised according to the industrial and technical specifications required.

Rocktouch, Digimax's partner in the distribution of industrial touch screen monitors, has also developed dedicated touch screen applications for the medical sector, such as the innovative Capacitive PCAP technology for multi-touch and the anti-bacterial treatment of industrial touch screen displays.

GRAPHIC MODULE DISPLAY

Main feautures of Graphic LCD Display

Graphic LCDs are born to be integrated into small to medium-sized solutions, are ideal for graphic view, and are simple and immediate to install.

With LCD technology, the properties of liquid crystals are used to modulate the passage of light beams from the plates located on the back of the device. The electrical contacts in these plates are then able to stress the pixels that make up the image inside the LCD module.

Graphic LCD modules can have various applications, including:

- Automotive electronics;
- Medical sector;
- Security and video surveillance systems;
- Industrial control and automation;
- Remote control.

The graphic LCD modules offered by Digimax

Digimax offers different solutions, in terms of size, color and resistance to particular temperatures. Single-color graphic LCDs range in size from 128x64 STN to 128x64 FSTN with various colors available.

The partners whose solutions Digimax proposes are reliable, competent, and with long experience behind them, with a propensity for studying new technologies and on quality control of devices placed on the market.

CHARACTER MODULE DISPLAY

Character module display

What is a character module display

Character module displays are compact size displays widely used, especially in industrial sector. Using liquid crystal display (LCD) technology, this module is able to take advantage of the light modulation properties of liquid crystals using flat display technology.

Character module displays are usually offered in standard format: 8x1, 8x2, 12x2, 16x1, 16x2, 16x4, 20x2, 20x4, 24x2, 40x2, 40x4; individual modules are integrated into complex interfaces, with the aim of increasing readability and visualization. Digimax character module display solutions can be integrated with a large number of interface including 8080, SPI and I2C.

These modules represent major graphemes such as English/Japanese, European, Scandinavian, Cyrillic and Hebraic/Arabic. The color of LED backlight can be customized: yellow-green, white, blue, black and grey.

Digimax offers character module displays with standard 5V operating voltage and 3V or 3,6V options upon request.

How work alphanumeric LCD displays

The main technology used in alphanumeric LCD panels including TN, STN, FSTN standards; visualizations mode are of two types:

- Positive: with dark characters in light background;
- Negative: with light characters in dark background.

Digimax has a wide range of character LCDs in a variety of formats: perfect solutions for those want realized compact systems for which display of information is required, such as audio systems, temperature management, home appliances, medical devices and general devices dedicated to reading information.

GRAPHIC OLED

The graphic OLED displays

Graphic OLED displays consist of extremely thin organic layers that can emit their own light, and images are reproduced when electric current flows through the organic compound. The intensity of the color is directly related to the amount of electrical energy reaching the pixel.

Unlike graphic LCD modules that polarize light from an external source, graphic OLED displays produce light autonomously through LED technology.

Due to the amount of different resolutions, the graphic OLED display can be adapted to a wide variety of industrial use applications.

The advantages of graphic OLED displays

Thanks to LED technology, OLED graphic displays have numbers of advantages, including:

- High brightness: thanks to their own light emission;
- Wider viewing angle of up to 175°;
- More advanced technology.

OLED displays are the ideal graphic displays for consumer and industrial applications such as, automotive control panels, medical devices, home appliances or home automation products, and more.

Digimax offers a wide range of OLED displays from the best brands on the market, discover our wide range and secure a personalized consultation.

CHARACTER OLED

What are character OLED modules

Character OLED’s are compact display that are widely used, especially in industrial settings due to their operative temperature range of -40°C to +80°C.

Using OLED technology these modules are able to emit their own light by managing complex parameters such as contrast and hue.

Character displays have specific standard formats that are integrated within more complex interfaces.

Raystar character OLED display

Raystar's character OLED displays include the option in yellow and white, which are the two most important and recommended colors in terms of long display life and good readability.

Raystar character OLED display modules include COB and COG technologies. Both technologies involve a chip that controls the screen, but in COB (Chip on Board) technology the chip is installed directly on the motherboard; in COG (Chip on Glass) technology, however, the chip is directly bonded to the glass.

The OLED display resolution options with characters offered by Digimax 16x2 and 20x4 have 6800, 8080, SPI and I2C interfaces available.

The OLED display module with characters is an ideal display for industrial applications such as audio, POS, measuring equipment or any character display needs.
