heat tolerance of an lcd touch screen brands

ImportantAnalogue resistive touch screens are rarely designed for temperatures well above or below zero. Our ULTRA GFG Touch is specified for temperatures from -40 degrees up to +75 degrees Celsius.

Many manufacturers specify their touch panels for standard temperature ranges from 0 degrees up to +35 degrees Celsius. This is usually sufficient for interior applications. Extended temperature requirements are generally defined from 0 degrees up to +50 degrees Celsius. Some manufacturers go even further and declare their standard resistive touch screens from -10 degrees up to +55 degrees Celsius.

Such touch screen are not suitable for outdoor use or the use in some desert or industrial environment, where temperatures can easily reach even higher or lower levels. Even in the extended temperature range, our patented ULTRA glass-film-glass technology is quite unique: already in the standard version, it is specified from -40 degrees up to +75 degrees Celsius and can be further protected by applying various filters to meet specific customer requirements.

Recent test reports, which we prepare on request of the customer, can be downloaded below. In this particular case, the customer selected the temperature range of -25 up to +70 to be tested.

Modern LCD screens have a great many uses. Not only are they now the system of choice for our home TVs and computers but their use in digital signage has made them a common sight in many shopping malls, airports and other locations with high quantities of people.

Even outdoor locations are no barrier to the use of modern LCD screens with outdoor digital signage a rising medium now seen in many town centers, car parks, front of stores and train station platforms.

All this out of home use means many screens operate in locations test the temperature limits of LCD displays. While waterproof screens and LCD enclosures designed for rugged applications provide the ability of the screen to operate-even in outdoor locations, one consideration often overlooked, is that of temperature.

LCD screens have a limited temperature range. Not only will the electronics inside an TV screen overheat and cause failure if the screen gets too hot, but the liquid crystal itself will begin to deteriorate under hot conditions.

The same is true of environments where temperatures fall below zero, causing a screen to stop functioning. A typical LCD TV has an operating range between 0°C (32°F) and 32°C (90°F).

Of course, many indoor and outdoor locations don’t suffer temperatures outside of this range, but many locations do and placing screens in these areas can prove challenging.

One of the problems with using a screen in hot locations is that the screen itself produces quite a bit of heat. When housed in an outdoor enclosure, the heat has to be continuously removed. While cooling fans combined with an air-vent normally carry out this task on an LCD, the need to prevent moisture from getting to the screen makes the task more complicated.

To get around this problem, specially shaped vents provide an exit for hot air while preventing rainfall and other moisture from getting in. In some locations where ambient temperatures are extremely high, screens need air conditioning to ensure they don’t exceed the maximum operating temperature.

In cold climates the opposite problem occurs. The need to keep heat in often requires insulation of the screen enclosure. Often this can trap enough of the heat generated by the screen itself to keep the internal temperature above minimum, but in some locations, even this isn’t enough. Heaters, controlled by thermostats provide extra heat in these circumstances, which enables the use of LCD displays in extremely cold locations such as ski-resorts and in Arctic regions.

AZ Displays continues to expand its product offering for the industrial and medical market. The newest IPS module, ATM1025L1-CT, is a unique wide aspect ratio IPS display that is designed to operate at -30 to 85 C. This LCD module has already received a lot of interest in the market for medical applications, time management systems, marine clusters, and several other designs. This 10.25″ display was designed with high performance in mind, with the following specifications:

In order for the LCD module to operate at extended temperatures, AZ Displays used premium polarizers and liquid crystal fluid to initiate the active matrix into operating with minimal latency at the low temperature end (-30 C), and high tolerance to warping and burning of the polarizer at extreme heat. This quality, along with high temperature rated IC’s and an option for optical bonding between LCD and touch screen make this module highly suitable for a wide array of applications and environments.

There are several industrial applications that require LCD displays to operate in extreme temperature environments such as in military, food processing, gas/fuel pumps, medical, manufacturing, and non-climate-controlled facilities, among others. Take note that typical monitors can only be used in environments with 0�C~50�C temperature range. UV exposure, moisture, and humidity also affect the overall temperature within a specific environment. iTech Company offers a range of LCD monitors that can function properly in a wide working temperature range from -30℃ to +80℃. These products are already proven and tested to maintain its original luminance under such temperatures.

While the range of operating temperature is a relevant consideration for the device to withstand extreme hot or cold environments, other factors must also be taken into account for the overall performance of the device. These includethe clarity of the image, environmental protection, LED backlighting, quality of the components, andvarious options available.

iTech Company’s products are equipped with these useful features to deliver great performance even in harsh working conditions. These are available in different monitor sizes and resolutions. It offers superior image quality with wide viewing angle. Some of the optional features include the touch screen functionality for interactive application and the level of brightness to ensure that the screen content is highly visible in all lighting conditions. Moreover, these wide operating temperature LCD displays are available in different types including open frame, panel mount, andchassis mount.

On the other hand, iTech Company also provides a customized design for its clients, which is a perfect solution for OEM customers. Just give us your specifications and we’ll come up with a product that will work great for your application.

Make sure not to push up against the glass or it will most likely crack the screen. What I do is cut through the adhesive, maybe some very thin flexible cards will cut the adhesive well.

Stockwell Elastomerics is a leading provider of gaskets for touch screens, displays and integrated touch panel assemblies that serve several functions: sealing, load distributing, gap filling, mechanical shock protection and over-press cushioning.

The obvious location is to seal the enclosure at the edge of the viewing area of the enclosure. The sealing function can be for simple dust sealing, light water exposure such as occasional water drips or cleaning or even more aggressive outdoor applications where there is heavy water exposure.

Often a touch screen gasket or display gasket will help spread the compression load of the housing or bezel on the display. Without a gasket, the enclosure that holds the display in place can create pressure points on the display. In some cases, these pressures can cause distortions, false contacts or short circuits.

Similar to load distributing, touch panel gaskets are used to fill gaps between the screen and the display and/or the screen and bezel. The display gasket will take up gaps generated by tolerance stack-ups in the device.

Display gaskets offer some degree of cushioning to protect the display from damage due to mechanical shock. In the event that a device is dropped or banged, the gasket will act as a touchscreen cushion, offering a limited amount of protection.

Touchscreen gaskets also serve as display cushions when a user presses on the display too hard. The gasket deflects, takes up and spreads the load offering some protection from over-press or overloading in a small area.

LCD dust seals and touch screen dust seals are the most basic requirement of display gasketing. These are often static (not portable), indoor applications where the device is not to be exposed to water. Sealing can be achieved by closed cell sponge materials or fine pore open cell materials such as PORON urethane foam.

Portable electronics or touchscreens used by the public such as gaming touchscreens or indoor information kiosks inevitably will be exposed to some water. This can come from cleaning and beverage splashing, or for portable devices – rain. These electronic devices are also more likely to be exposed to mechanical shocks, such as banging or dropping. Closed cell or compressed microcellular foam materials will offer more protection against incidental, light water exposure.

Outdoor displays such as outdoor information kiosks, ATMs and remote monitoring equipment require more design consideration. To contend with environments such as direct or wind-driven rain, sealing an enclosure, case or housing from ingress requires the proper material as well as proper compression on the gasket. Silicone foam or silicone sponge materials are preferred. Silicone gaskets remain flexible at low temperatures allowing for continued sealing against melting ice and snow as well as protecting against mechanical shock where many other materials will firm up in the cold and transfer energy. Other key features are: closed cell structure, low-stress relaxation, UV and ozone resistance, and general long life.

Ruggedized electronics typically need to withstand much more aggressive environments. This may include passing rain or wash down tests such as IP65, IP66 and possibly IP67. Beyond sealing, they often need to survive the cold soak drop test, tumbling, EMI susceptibility, and a variety of other tests depending on usage. View more information on ruggedizing electronics.

Light leaking is sometimes a concern with certain LCD or LED display applications. This can be addressed with black gasketing with either a very thin adhesive or a black supported adhesive. A common material configuration for this is soft PORON urethane foam with 3M 9795B adhesive. The 3M 9795B is a film supported double coat adhesive with a black PET support layer that does not pipe light.

Touchscreen gaskets and display gaskets tend to have narrow walls that don’t always lend themselves to easy installation. This can be addressed in a few ways such as fixturing or utilizing the centers as temporary supports. The preferred adhesives for touchscreen gaskets and display gaskets are repositionable adhesives such as Adchem 8311M or 3M 9415 depending on the bond strength required. Stockwell Elastomerics also offers medium and high bond strength adhesives for permanent bonding. View the current listing of pressure sensitive adhesive options.

Most touch panel or touch screen manufacturers offer guidelines for gasketing. These typically show the active screen area, viewing area, and the gasket area. The manufacturer offers various recommendations on adhesive strength and gasket material type, but caution should be taken since each application will vary.

Broad recommendations such as “closed cell foam” do not take into consideration factors such as stress relaxation, compression set, long term sealing performance, outgassing, plasticizer interaction, cost, and manufacturability. Over-designing the gasket can drive the cost up, whereas under designing could result in damaged devices and leaks when the units are in the field. Stockwell Elastomerics can offer guidance on design and manufacturability of touchscreen gaskets or touch panel gaskets. Key design points include:

The interior opening of the gasket should follow the touch screen manufacturer’s recommendation that stays clear of the active area. The outer dimension are defined by the available space behind the bezel or in the case. A rough rule of thumb is that the gasket wall should be 1.5x the thickness. (Example: .062″ thick gasket should have a gasket with .093″ or greater flange width.) This allows for die cutting and makes for a stable gasket when installed. A gasket that is taller than it is wide tends to fold over during compression. The exception to this is when the gasket is captive in a groove.

It is important to keep in mind the clamping loads. While wider gasket walls generally seal better, the overall surface area is directly related to the loads applied to the LCD and touchscreen. Compression Force Deflection curves of various materials are available to aid designers.

Some housing designs allow the touch panel gasket to wrap around the sides to make a tighter fit in the housing. Wrapping the gasket also gives the touch panel assembly additional cushioning for mechanical shock.

Proper compression of the gasket is critical to sealing. A rigid bezel or frame is required to prevent bowing between fasteners. Softer materials can help offset this however there are some limitations. Closed cell gasket materials help prevent wicking through the material but may not be soft enough. Soft open cell materials can be used but require more than 50% deflection (.062″ thick deflected to .031″ thick) in order to close the cell openings.

The gasket thickness will depend on the designed gap in the enclosure, the fastening scheme, rigidity of the housing and the level of sealing required. Many touch screen gaskets are thin and soft but as the display gets larger the tolerance stacks typically get larger as well. This may require a thicker gasket depending on the fastener locations.

PORON microcellular urethane foams are designed for electronic applications, therefore there are many standards, off-the-shelf thickness and firmness options available. Further, PORON is cast to an accurate thickness tolerance. PORON in thickness of .062″ and greater is cast to ± 10%. This is a very tight tolerance for a cellular gasketing material.

Designing the touch panel gasket for manufacturability can keep costs down – both part cost and touch panel assembling cost. For mid- and high-volume quantities, die cutting is the preferred method. A steel rule die can be produced quickly and inexpensively to allow the gasket to be kiss-cut against the adhesive release liner. Kiss-cutting allows the gasket installer to peel the gasket from a roll. Kiss-cut parts drastically improve throughput during assembly as compared to individually removing a liner from a loose part.

Some OEMs and contract manufacturers prefer to have the center of the gasket remain in place, held in place with small, breakaway tabs. Leaving the centers intact allows for easier positioning on the display when a fixture is not being used. Low tack, clean peeling adhesive is needed.

Specification requirements help with material selection, for example, NEMA 4, IP 65 or IP 66 will require closed cell or solid materials in order to pass testing. Less aggressive requirements such as NEMA 12 and IP 54 allow for more material options.

Typical UL specifications are UL 94, UL 508 (UL 60947) and UL 50. UL 94 addresses a flame requirement, UL 508 (UL 60947) is suitability for industrial controls, and UL 50 and UL 50E are for gasketing. Other UL specifications may apply depending on how and where the end product is being used.

Elo takes great pride in controlling many aspects of an LCD display, including brightness, contrast, color and other parameters. For more information about some of the parameters and tolerance expected from one monitor to the next, even when comparing identical monitors, please read the information below.

Analog video signal:Scalar needs to convert the analog to a digital signal and it’s unavoidable that there will be distortion of color performance in this process.

Color format:Different color formats can cause different color performance. RGB uses additive color mixing because it describes what kind of light needs to be emitted to produce a given color. RGB stores individual values for red, green and blue. RGBA is RGB with an additional channel, alpha, to indicate transparency.

Elo includes some basic settings in the On-Screen Display (OSD) to control the appearance of the display. The available adjustments vary with the type of monitor. Please reference the “User Guides” located under the “Resource” section on the product’s webpage. Check the following settings and any other options that can affect the picture:

Furthermore, the age and use of a monitor will affect its LCD screen. It is important to keep in mind that monitor manufacturers can use multiple part suppliers for the same products—two “identical” monitors might have LCD panels that are not from the same supplier.

You don"t necessarily want to set the monitors to the same settings. Even though they are usually close, two of the same exact monitors can show colors slightly different. You may need to adjust the RGB settings on one monitor to match the other. The best way to adjust them is to bring up a perfectly red screen on both monitors (use MS Paint because you can set the color just the way you want) and then adjust them till they look the same. Repeat for blue and green. Once you get it the way you want, write down the RGB settings just in case your monitor resets and you lose your settings.

Each monitor is tested at the factory, and the color is manually calibrated to ensure it is within an allowable range. Please note, the Elo warranty does not cover color uniformity differences between two monitors. In fact, both are in the manufacturer specification for uniformity.

Elo does “White Balance” to make sure all color temperatures (5500K, 6500K, 7500K and 9300K) are within the spec and records all of the data for each Elo monitor on the production line

Onboard TFT LCD displays the screen in our life more and more applications, so do you know what the requirements of the car LCD screen? The following is a detailed introduction:

First of all, the working environment of cars is relatively complicated. In the morning, in the evening, in the summer, in the autumn and in the winter, in different parts of the world, cars are required to work. Cars are often exposed to the sun in the summer, and the cabin temperature can reach more than 60 degrees. The electronics inside must be able to work properly with the car. In some northern areas, the winter is so cold that regular LCD screens don’t work. These need to resist the high and low temperature of the LCD screen, for the owner to display driving information, escort.

You can see from this, the requirement of the automobile LCD screen is very tall. Under extreme conditions from -40 ° c to 105 ° c, it must be kept intact for more than 300 hours.

While the highlighted LCD display screen can work normally in extreme temperatures, it also needs to be visible and waterproof under ultra-bright direct sunlight. In addition, the GPU and the display screen of the LCD module will generate heat during use, and the higher the resolution of the LCD screen, the greater the heat. Therefore, it is also a big technical problem to develop a set of hardware products that meet the requirements of the vehicle. For these reasons, compared with the LCD display screen resolution of mobile phones, computers, televisions, etc., the display screen of cars is relatively conservative.

Now the LCD display screen technology has become more and more mature, the on-board LCD screen applications are more and more, the LCD display screen has been able to fully meet the changing working environment and work requirements ofthe car.LCD display screenshave made a big shift in automotive applications. With the development of science and technology, the development momentum of the onboard LCD screen will be very rapid.

The on-board LCD display screen adopts LCD technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, onboard electronic technology, and so on to display the information bar LCD display screen on the mobile vehicle, which is different from the ordinary strip LCD display screen installed in a fixed position. On the technical level, due to its special application environment, the requirements for the on-board long strip LCD display screen are much higher than the traditional LED display screen, which requires moisture-proof, rain-proof, lightning-proof, sun-proof, dustproof, cold-proof, anti-corrosion, anti-static, anti-interference, anti-seismic, anti-ultraviolet, anti-oxidation. At the same time must have over the current, short circuit, over-voltage, under-voltage protection, and other functions, in order to become a qualified vehicle screen.

As a more novel communication media of advertising information, the on-board LCD screen can not only store a large amount of text information, but also control the display mode of text and font through the built-in microprocessor to realize the display function of timing, and can also be moved and spread everywhere. It has completely got rid of the shackles of the traditional display screen and has the characteristics of mobile display, so it is highly praised by new media advertisers.

Through market investigation and analysis, it can be found that the audience of the onboard display screen is concentrated. Taking the on-board LCD screen of the bus as an example, it can provide important travel information and route information for passengers. In addition, the advertising effect is outstanding. Buses in cities are still one of the main means of public transportation, with millions of passengers taking them every day. It carries a large number of people, more than ten minutes on the bus “leisure time” is leisurely and boring. If it has a mobile screen in front to play news, entertainment, weather, advertising information, etc., then the active “cramming” media in front of it can attract passengers’ attention to the greatest extent, and it must be able to achieve good advertising effect.

Both subway strip screens and taxi car LCD screens have the common characteristics of a wide audience and huge market potential. Once the on-board LCD screen products are promoted and launched on a large scale, the media with large audiences and low advertising costs will surely attract the attention of many enterprises and advertisers. Government departments can also use the on-board Lcd display screen to promote public welfare, which has important significance and role.
