The viewing angle amounts to 140º horizontally and 110° vertically. This module comes with a 24-bit digital RGB interface and has a wide operating temperature range of -30 to +80°C.

“Portable outdoor devices are liable to fall down and are exposed to low temperatures, heat and humidity. Even in these conditions, they should always work reliably, and our components are designed for that purpose,” says Eberhard Schill, Manager Distribution and Marketing, Kyocera Display Europe.

In the design of the LCD screen, the selection of what temperature range of liquid crystal materials will be considered. Usually, our TFT LCD screen work is divided into normal temperature 0-50 degrees, wide temperature -20-70 degrees, super-wide temperature -30-80 degrees, even customers will choose -40 degrees of extremely special materials to design. So, does the LCD still work at the limit temperature?

Actually, this question is a little ambiguity, as we know, for example, the wide temperature scope of work is – 20-70 degrees, so first of all, in less than 20 degrees below 0 and higher than 70 degrees of circumstances, the LCD panel will not be able to work in theory, but, if you haven’t reached 70 degrees and the temperature of minus 20 degrees, but already very close to, can be said to be the limiting temperature, the LCD screen can work normally?

This problem is also a problem many customers will put forward, many customers use the wide temperature LCD, in the case of very low temperature, the word becomes very weak, and in the case of very high temperature, the word becomes very deep, how is this?

In fact, the LCD screen goes a long way to explaining the principle, the LCD panel to display all sorts of design or pen, is due to the liquid crystal box of LCD in work, andliquid crystal, just as its name implies is liquid, must be affected by the environment, high-temperature liquid crystal will be fever, flow speed, the feedback is on display, color is very deep. Under the condition of low temperature, the liquid crystal will start to crystallize and flow slowly, and the color on the display will become very shallow. It is not that it cannot display normally, but the display time will be much slower than the normal temperature.

So everyone should be able to understand, the operating temperature of the LCD screen, that is, in this temperature range it is able to work, not because of environmental factors do not display or do not refresh the situation.

Generally speaking, the wide temperature LCD screen, for example, starting from 5 degrees below zero and 50 degrees centigrade, the speed of the display will begin to change, to minus 20 degrees and 70 degrees above freezing, reached the limit temperature, feedback to the screen is no display or a dark state, already can’t use, so liquid crystal often advise clients, if the actual temperature is close to the limit temperature, it must choose a wider temperature range of LCD screen.

STONE has more than 20 years of industrial LCD production experience. STONE HMI solutions are now widely used in a variety of industrial embedded areas of advanced civil products: such as home and office automation, medical equipment, beauty machines, vending machines, power control systems, and excavators.STONE is highly recognized by national instruments, state grid corporation of China, Thyssenkrupp Elevator, and other partners for all kinds of equipment, such as gas stations and charging piles, that require a stable operating temperature of TFT LCD screen and relatively severe operating environment.

According to the popularization of display applications, the TFT LCD display have to adapt the Extreme Temperature and Different EnviromentsFIRST Components/ Evervision’s Wide Temperature TFT LCD Series are designed specifically for operation in harsh environments and under changing temperature. Furthermore, we have a solution for low temperature environment. Let’s find out!

The LCD in cold temperatures may cause misreading because of the response time of LC (physical characteristics). It will turn slowly and make the screen overlap. Additionally, it may cause permanent damage to the display if LCD panel left in such conditions for extended periods.

Fortunately, ​there are a number of solution such as specialty liquid crytals (LCs) and other materials for application requiring the use of a display in extreme environmental condition. FIRST Components/ Evervision Wide Temperature TFT LCD Display overcome these challenges through the use of applied heating and cooling solutions.​

At present, the common TFT LCD modules on the market have a wide range of definitions of -20~70 °C. For industrial control, vehicle and outdoor products, this temperature range always can’t meet the needs of such usage.

Fortunately, our Wide Temperature TFT LCD Display can work under extreme environments with operating temperatures ranging from -30°C to +80°C, and the maximum for some models can reach 85°C. These TFT displays are full color LCDs available in industry standard sizes rangingfrom 3.5″ to 15.6” TFT LCD display and widely used in cold or heat condition throughout the world.

In low temperature environment, liquid crystals will be condensed and cause the screen blanked out. In order to prevent the problem, you may need to add a Glass Heater to your TFT LCD Module.

It can optimize the LCD visual clarity and operate normally by heating up to the right temperature. With Glass Heater, displays and touch screens remain usable in cold, high humidity/low dew point environments and locations where ambient temperature can change quickly.

This note will discuss the operating and storage temperatures for LCDs. Each LCD has a specified operating and storage temperature listed in the specification sheet of the display and its controller. Typically, this temperature is specified as -20°C to 70°C for the operating temperature and -30°C to 80°C for the storage temperature. Considerations should be made when operating or storing the display near the maximum and minimum temperatures.

For applications where the display must operate in extreme temperature environments, measures can be taken to avoid damaging the display and the embedded display controller. This resource will discuss the precautions and preventions of operating and storing a display at the maximum and minimum temperatures specified.

The environment a display is operated and stored in can have effects on things such as: voltage, contrast, signal integrity, and system performance. The effects of temperature on the display become more significant at the two extremes. Common display temperature ranges can be found as three common sets. Below are the three most common temperature ranges for LCDs. The temperature ranges can be confirmed in the datasheet of the display and its controller.

At very high temperatures, the effects can be seen on the electronic components and the liquid crystal of the display. The effects from an environment that is too hot will cause a darkening of the display, decreased/limited visibility, unreliable communications, and potential damage to the IC due to increased conductivity. The liquid crystal in the display will begin to degrade at very high temperatures. Overheating the display can cause dark spots to appear or result in a fully dark screen.

Both internal and external heat should be taken into consideration when operating the display. The environmental heat can contribute to overheating the device internally. The most common source of internal heat generation is from the backlight. The backlights can operate at high voltages and current consumptions to supply power to the backlight LEDs. This internal heat generation should be considered in high temperature environments.

To prevent internal and external overheating, fans and vents can be incorporated into the system to keep the display within the specified operating conditions. Precautions to avoid moisture entering the system should be taken when including vents. Moisture can cause electrical shorting, especially at high operating temperatures.

Contrast can be affected when a display is operated in ultra-high temperatures. Higher temperatures result in an increase in conductivity. This means that less voltage is required to provide the same contrast to the pixels. These effects can become more prominent when using graphic or character LCDs. Undesired effects such as a black screen can occur if the operating environment is above the specified temperature range.

The liquid crystal that is used in the display can get disoriented at very high temperatures. At these temperatures, the liquid crystal molecules can become unaligned and light will not pass through as desired. This disorientation of the liquid crystal molecules can result in a dim or partially dim image on the display. The viscosity of the liquid crystal decreases at high temperatures. The causes unreliable control of the pixels, feedback on the display, and deeper colored images.

Operating and storing a display at temperatures higher than the specified ranges can cause permanent damage to the device. Melting of display properties can occur if operating or storing the display at temperatures that exceed the limits.

A display that is operated or stored at very low temperatures will have the opposite effects in comparison to high temperatures. The effects of cold temperatures can be seen as a slowed response time, increased power consumption, reduced contrast, and a non-operational display. Storing and operating a display in low temperatures will have fewer permanent effects than at high temperatures.

At low temperatures, the liquid crystal in the display will begin to freeze. This causes reduced mobility of the liquid crystal molecules and light cannot pass through as intended. This can cause reduced visibility and reduced color depth of the displayed image. Opposite to a very hot environment, the contrast will be reduced at low temperatures.

The effects of extremely low temperatures on a display are less likely to be permanent than in hot temperatures. The likely outcome of operating a display below the recommended range is that the display will not turn on. This removes the opportunity for internal circuits to short. Once the display is returned to a temperature within the specified range, the liquid crystal will typically return to normal behavior.

Different liquid crystal fluid has different temperature properties. Extreme temperature liquid crystal exists for certain applications but can be more expensive. Twisted nematic (TN) LCD’s have the temperature ranges listed in this note.

Semiconductors operating in very low temperatures will have decreased conductivity due to increased resistance. The LCD controller, often incorporated on the glass of the LCD, will operate at lower speeds in very cold environments.

Compensations to adjust for cold environments can include heaters, voltage regulators and thermistors to adjust power determined by temperature. Temperature compensating IC’s can be included in the applications on both ranges of the temperature spectrum.

It is strongly recommended to operate and store the display within the specified temperature ranges to avoid damaging the display. Operating the display at temperatures that exceed the specified range can cause the display to malfunction, become unreliable and cause permanent damage to the device. Precautions can be taken to compensate for the environment and to avoid exceeding the specified ranges.

When selecting a display, it is important to consider the temperatures at which it will work and, in addition, allow for the extraordinary temperature conditions that may occur in the application environment.

Today"s standard TFT displays usually have a working temperature range of -20 to + 70°C. TFT displays with a narrower operating temperature range, e.g. 0 .. + 70°C or 0… + 50°C are quite rare.

If the application works outdoors, we are naturally also interested in the lower temperature range. Minus 20°C occurs almost every winter in European conditions. It is only a few days, but it is necessary to consider such temperature. Temperatures around -30°C occur even more rarely, but there are years with such low temperatures. If you have a device that must be able to operate at such low temperatures, then the display with a temperature range of -30 to + 80 (85)°C is a clear choice.

However, there are also cases where a short-term reduced or even minimal readability of the display operating at a temperature lower than the allowed minimum are not a problem. However, there is a catch that under these circumstances the display may be irreversibly damaged. The point is that the storage temperature range is often the same as the working temperature range, so the manufacturer does not even allow to "store" or to expose the display to lower temperatures, even though in the off-state. This fact underlines the importance of considering the temperatures at which your equipment can work.

With our heater electronic control mechanism with temperature sensors, the heater control board can control the heater on or off and then regulate the internal system temperature change. At the low-temperature condition, the mechanism starts from the pre-heating process, and then the LCD panel turns on when it"s 4 degrees Celsius. When the internal temperature drops below 7 degrees, the heater will turn on to keep the system above 0 degrees Celsius.

On the other side, the mechanism maintains the power switch to protect from overheating at high-temperature conditions. The power will turn off over 65 degrees C and back to turn on status when the internal temperature drops back to 55 degrees. With an advanced fan cooling system design, the turn-off temperature is applied to this mechanism. The wide temperature range system technology shows excellent reliability in harsh environment applications combined with mechanical NMEA/IP degree front bezel and other technical module integration.

A number of TFT solutions are offered. Serial TFT, I2C TFT, USB TFT, RS422 TFT, SPI TFT and Parallel 24bit RGB TFT. TFT, or Thin Film Transmissive, display technology uses the same control techniques as an LCD, but permits larger screen sizes by adding transistors to address pixels by row and column rather than individually. Additionally, TFT units offer red, green, and blue elements for each pixel to produce a full range of colour output. The brightness of each colour element is individually controlled by a number of bits, typically between 5 and 8, to produce up to 16 million colours. These units are driven by an LED backlight which requires moderate power input, and can be varied to control brightness, typically up to 600 nits. These units have an operating range similar to LCDs of -20C to 70C, but offer increased contrast performance, typically up to 500:1, and viewing angles of up to 140 degrees. High display resolution and touch overlay options make this technology attractive to higher end HMI applications. TFT is available on GTT, EVE, HTT and Parallel Displays.
