General Digital can integrate virtually any LCD display size/resolution, from almost any panel manufacturer (OEM), into our enclosures. To assist in selecting the right panel for your application requirements, we have provided a list of commonly used or recommended panels for standard/low luminance, high brightness, sunlight readable and NVIS compatible needs.

New display models are constantly being introduced to the market by the LCD manufacturers, making it extremely difficult for us to maintain a comprehensive list. For this reason, we encourage you to speak with a Sales Engineer to share your price and performance objectives, so we can assist you in making the best display selection.

General Digital has provided a sample listing of some common transmissive displays that are not sunlight readable. Typically, these displays are suitable for applications that are not going to require specialty functionality, such as sunlight readability or NVIS compatibility, and for customers with cost-sensitive budgets.

LCD backlight produces sufficient luminance for use in office, shaded and low ambient/darkness light levels. However, luminance is insufficient to overcome reflected light for use in direct sunlight.

This type of technology boosts the efficiency of the backlight’s light utilization and minimizes surface reflection of ambient light. It is a transmissive LCD module that produces high contrast images, even in bright outdoor light and direct sunlight. These displays feature a wider color reproduction range than reflective LCDs. Featuring an LED backlight, these displays consume very little power and produce very little heat, making them ideal for integration into fully sealed enclosures, which are devoid of ventilation holes and cooling fans to dissipate heat. They also provide the additional benefit of a wide operating/storage temperature (as great as -30°–85° C), so that they can endure exposure to greater internal ambient temperatures.

As a design note, we have found that these panels work best when coupled with an overlay that has an antireflective (AR) coating. Overlays that inhibit transmissivity (e.g., resistive touch screen) or have antiglare (AG) coatings will significantly reduce the panel’s performance in high ambient lighting conditions. Since transmissive displays produce greater brightness from their LED backlights than traditional transflective displays, they are regarded as a better outdoor solution, as they can generate high contrast in total darkness, in direct sunlight or on a cloudy/hazy afternoon.

T-EVT technology uses the high brightness/efficiency LED backlight as a light source while minimizing the surface reflection of ambient light. The result is an LCD that produces high contrast images even in bright outdoor light or direct sunlight.

This type of panel incorporates a highly reflective backlight that reflects the ambient lighting back out of the display to enhance its native brightness produced by its active backlight. Like the Transmissive-Enhanced View Displays, GenFlective panels work best when coupled with anAR-coatedoverlay. They are least effective with overlays that retard the light transmission (e.g., resistive touch sensors) or have a matte finish.

T-EVT technology uses the high brightness/efficiency LED backlight as a light source while minimizing the surface reflection of ambient light. The result is an LCD that produces high contrast images even in bright outdoor light or direct sunlight.

These displays feature a value-add backlight, typically made from high efficiency LEDs. These displays produce significant active luminance. Often, the peak luminance is limited by internal ambient temperature constraints or must be connected to an intelligent backlight controller and thermal sensor that will automatically reduce brightness/power to avoid over-temperature conditions or thermal shutdown. The high luminance output makes them ideal for use with a wide variety of overlays such as touch sensors, EMI filters, heaters, etc.

Sunlight readable displays use a General Digital-enhanced, highly efficient, super bright/sunlight readable LED backlight to provide maximum functional brightness. The addition of surface treatments such as antireflective coatings and optical bonding reduce surface reflections and increase contrast so displays can be used in direct sunlight.

If our stock offering does not suit your needs in terms of size, fit or function, please contact a Sales Engineer and we will work with you to configure a system to your specifications.

The medical industry is one of those sectors that benefits from the advancement of the technology. The use of the latest liquid crystal displays significantly improves the patients’ welfare and the overall hospital ambiance.

In bigger hospitals, proper coordination is needed for a well-organized operation of various departments. These include moving the patients efficiently. LCD monitors are being used in order to display related information about patients and improve their flow as well as increase their family’s awareness about their locations. It also shows which rooms are available, along with other important information.

Moreover, LCD screens could also function as a stand-alone TV and as a computer monitor. With these, it is capable of internet and local area network connectivity. In a hospital or any other bigger setting, such connectivity is useful to monitor several LCD screens remotely.

The modern day medical system are already utilizing the latest LCDs for a more detailed and accurate diagnosis. An example of this is a procedure called Mammography.

Advanced LCD monitors are now being used in hospitals and other medical facilities to deliver reliable medical-grade visualization and surgical displays. Some are even equipped with OR integration technologies.

LCD screens are being used in wards in order to monitor patients and their corresponding beds for information. Most hospitals have central monitor in the whole ward that can be used in case of any emergency along with other information in the area.

In the waiting rooms of most hospitals, LCD monitors are being used to share important medical information such as how to avoid catching dengue with corresponding images or videos. This acts as a way to inform or educate the visitors. LCD screens also acts as a TV and thus, provides entertainment in the waiting rooms of hospitals.

Many hospitals nowadays are using LCDs as digital navigation tools to lead their visitors around the area. Many of these have even touchscreen features.

Medical-grade LCD displays are markedly superior as compared to those which are designed for commercial use for a number of reasons. First, it underwent an inherent component and manufacturing quality process which are compliant to highly rigorous medical standards. It also passed very sophisticated QA control systems and software compatibility procedures.

Medical displays are also designed to have greater luminance stability throughout their lifetime. This gives high quality image presentation and diagnostic yield to the clinician. Moreover, it extends the life of such costly device. For a better image presentation, it features higher maximum luminance in contrast to the consumer-grade monitors. It has also higher contrast ratio and better grayscale reproduction.

With all of the above-mentioned features, medical displays are ideally suited to the demands of a hospital setting or any other medical facility. There is no doubt that they are superior to those displays which are designed and manufactured for commercial use.

The availability of a more advanced digital technology such as the latest LCD screens has changed the way medical facilities and hospitals operate.

The use of liquid crystal displays (LCDs) in user interface assemblies is widespread across nearly all industries, locations, and operating environments. Over the last 20 years, the cost of LCD displays has significantly dropped, allowing for this technology to be incorporated into many of the everyday devices we rely on.

The odds are high you are reading this blog post on a laptop or tablet, and it’s likely the actual screen uses LCD technology to render the image onto a low-profile pane of glass. Reach into your pocket. Yes, that smartphone likely uses LCD technology for the screen. As you enter your car, does your dashboard come alive with a complex user interface? What about the menu at your favorite local drive-thru restaurant? These are some everyday examples of the widespread use of LCD technology.

But did you know that the U.S. military is using LCD displays to improve the ability of our warfighters to interact with their equipment? In hospitals around the world, lifesaving medical devices are monitored and controlled by an LCD touchscreen interface. Maritime GPS and navigation systems provide real-time location, heading, and speed information to captains while on the high seas. It’s clear that people’s lives depend on these devices operating in a range of environments.

As the use of LCDs continues to expand, and larger screen sizes become even less expensive, one inherent flaw of LCDs remains: LCD pixels behave poorly at low temperatures. For some applications, LCD displays will not operate whatsoever at low temperatures. This is important because for mil-aero applications, outdoor consumer products, automobiles, or anywhere the temperature is below freezing, the LCD crystal’s performance will begin to deteriorate. If the LCD display exhibits poor color viewing, sluggish resolution, or even worse, permanently damaged pixels, this will limit the ability to use LCD technologies in frigid environments. To address this, there are several design measures that can be explored to minimize the impact of low temperatures on LCDs.

Most LCD displays utilize pixels known as TFT (Thin-Film-Transistor) Color Liquid Crystals, which are the backbone to the billions of LCD screens in use today. Since the individual pixels utilize a fluid-like crystal material as the ambient temperature is reduced, this fluid will become more viscous compromising performance. For many LCD displays, temperatures below 0°C represent the point where performance degrades.

Have you tried to use your smartphone while skiing or ice fishing? What about those of you living in the northern latitudes - have you accidently left your phone in your car overnight where the temperatures drop well below freezing? You may have noticed a sluggish screen response, poor contrast with certain colors, or even worse permanent damage to your screen. While this is normal, it’s certainly a nuisance. As a design engineer, the goal is to select an LCD technology that offers the best performance at the desired temperature range. If your LCD display is required to operate at temperatures below freezing, review the manufacturer’s data sheets for both the operating and storage temperature ranges. Listed below are two different off-the-shelf LCD displays, each with different temperature ratings. It should be noted that there are limited options for off-the-shelf displays with resilience to extreme low temperatures.

For many military applications, in order to comply with the various mil standards a product must be rated for -30°C operational temperature and -51°C storage temperature. The question remains: how can you operate an LCD display at -30°C if the product is only rated for -20°C operating temperature? The answer is to use a heat source to raise the display temperature to an acceptable range. If there is an adjacent motor or another device that generates heat, this alone may be enough to warm the display. If not, a dedicated low-profile heater is an excellent option to consider.

Made of an etched layer of steel and enveloped in an electrically insulating material, a flat flexible polyimide heater is an excellent option where space and power are limited. These devices behave as resistive heaters and can operate off a wide range of voltages all the way up to 120V. These heaters can also function with both AC and DC power sources. Their heat output is typically characterized by watts per unit area and must be sized to the product specifications. These heaters can also be affixed with a pressure sensitive adhesive on the rear, allowing them to be “glued” to any surface. The flying leads off the heater can be further customized to support any type of custom interconnect. A full-service manufacturing partner like Epec can help develop a custom solution for any LCD application that requires a custom low-profile heater.

With no thermal mass to dissipate the heat, polyimide heaters can reach temperatures in excess of 100°C in less than a few minutes of operation. Incorporating a heater by itself is not enough to manage the low temperature effects on an LCD display. What if the heater is improperly sized and damages the LCD display? What happens if the heater remains on too long and damages other components in your system? Just like the thermostat in your home, it’s important to incorporate a real-temp temperature sensing feedback loop to control the on/off function of the heater.

The first step is to select temperature sensors that can be affixed to the display while being small enough to fit within a restricted envelope. Thermistors, thermocouples, or RTDs are all options to consider since they represent relatively low-cost and high-reliability ways to measure the display’s surface temperature. These types of sensors also provide an electrical output that can be calibrated for the desired temperature range.

The next step is to determine the number of temperature sensors and their approximate location on the display. It’s recommended that a minimum of two temperature sensors be used to control the heater. By using multiple sensors, this provides the circuit redundancy and allows for a weighted average of the temperature measurement to mitigate non-uniform heating. Depending on the temperature sensors location, and the thermal mass of the materials involved, the control loop can be optimized to properly control the on/off function of the heater.

Another important consideration when selecting a temperature sensor is how to mount the individual sensors onto the display. Most LCD displays are designed with a sheet metal backer that serves as an ideal surface to mount the temperature sensors. There are several types of thermally conductive epoxies that provide a robust and cost-effective way to affix the delicate items onto the display. Since there are several types of epoxies to choose from, it’s important to use a compound with the appropriate working life and cure time.

For example, if you are kitting 20 LCD displays and the working life of the thermal epoxy is 8 minutes, you may find yourself struggling to complete the project before the epoxy begins to harden.

Before building any type of prototype LCD heater assembly, it’s important to carefully study the heat transfer of the system. Heat will be generated by the flexible polyimide heater and then will transfer to the LCD display and other parts of the system. Although heat will radiate, convect, and be conducted away from the heater, the primary type of heat transfer will be through conduction. This is important because if your heater is touching a large heat sink (ex. aluminum chassis), this will impact the ability of the heater to warm your LCD display as heat will be drawn toward the heat sink.

Before freezing the design (no pun intended) on any project that requires an LCD display to operate at low temperatures, it’s critical to perform low temperature first. This type of testing usually involves a thermal chamber, a way to operate the system, and a means to measure the temperature vs time. Most thermal chambers provide an access port or other means to snake wires into the chamber without compromising performance. This way, power can be supplied to the heater and display, while data can be captured from the temperature sensors.

The first objective of the low-temperature testing is to determine the actual effects of cold exposure on the LCD display itself. Does the LCD display function at cold? Are certain colors more impacted by the cold than others? How sluggish is the screen? Does the LCD display performance improve once the system is returned to ambient conditions? These are all significant and appropriate questions and nearly impossible to answer without actual testing.

As LCD displays continue to be a critical part of our society, their use will become even more widespread. Costs will continue to decrease with larger and larger screens being launched into production every year. This means there will be more applications that require their operation in extreme environments, including the low-temperature regions of the world. By incorporating design measures to mitigate the effects of cold on LCD displays, they can be used virtually anywhere. But this doesn’t come easy. Engineers must understand the design limitations and ways to address the overarching design challenges.

Display size, contrast, color, brightness, resolution, and power are key factors in choosing the right display technology for your application. However, making the right choice in how you feed the information to the display is just as vital, and there are many interface options available.

All displays work in a similar manner. In a very basic explanation, they all have many rows and columns of pixels driven by a controller that communicates with each pixel to emit the brightness and color needed to make up the transmitted image. In some devices, the pixels are diodes that light up when current flows (PMOLEDs and AMOLEDs), and in other electronics, the pixel acts as a shutter to let some of the light from a backlight visible. In all cases, a memory array stores the image information that travels to the display through an interface.

According to Wikipedia, "an interface is a shared boundary across which two separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. Some computer hardware devices such as a touchscreen can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system.” In other words, an interface is something that facilitates communication between two objects. Although display interfaces serve a similar purpose, how that communication occurs varies widely.

Serial Peripheral Interface (SPI) is a synchronous serial communication interface best-suited for short distances. It was developed by Motorola for components to share data such as flash memory, sensors, Real-Time Clocks, analog-to-digital converters, and more. Because there is no protocol overhead, the transmission runs at relatively high speeds. SPI runs on one master (the side that generates the clock) with one or more slaves, usually the devices outside the central processor. One drawback of SPI is the number of pins required between devices. Each slave added to the master/slave system needs an additional chip select I/O pin on the master. SPI is a great option for small, low-resolution displays including PMOLEDs and smaller LCDs.

Philips Semiconductors invented I2C (Inter-integrated Circuit) or I-squared-C in 1982. It utilizes a multi-master, multi-slave, single-ended, serial computer bus system. Engineers developed I2C for simple peripherals on PCs, like keyboards and mice to then later apply it to displays. Like SPI, it only works for short distances within a device and uses an asynchronous serial port. What sets I2C apart from SPI is that it can support up to 1008 slaves and only requires two wires, serial clock (SCL), and serial data (SDA). Like SPI, I2C also works well with PMOLEDs and smaller LCDs. Many display systems transfer the touch sensor data through I2C.

RGB is used to interface with large color displays. It sends 8 bits of data for each of the three colors, Red Green, and Blue every clock cycle. Since there are 24 bits of data transmitted every clock cycle, at clock rates up to 50 MHz, this interface can drive much larger displays at video frame rates of 60Hz and up.

Low-Voltage Differential Signaling (LVDS) was developed in 1994 and is a popular choice for large LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is a great solution because of its high speed of data transmission while using low voltage. Two wires carry the signal,  with one wire carrying the exact inverse of its companion. The electric field generated by one wire is neatly concealed by the other, creating much less interference to nearby wireless systems. At the receiver end, a circuit reads the difference (hence the "differential" in the name) in voltage between the wires. As a result, this scheme doesn’t generate noise or gets its signals scrambled by external noise. The interface consists of four, six, or eight pairs of wires, plus a pair carrying the clock and some ground wires. 24-bit color information at the transmitter end is converted to serial information, transmitted quickly over these pairs of cables, then converted back to 24-bit parallel in the receiver, resulting in an interface that is very fast to handle large displays and is very immune to interference.

Mobile Industry Processor Interface (MIPI) is a newer technology that is managed by the MIPI Alliance and has become a popular choice among wearable and mobile developers. MIPI uses similar differential signaling to LVDS by using a clock pair and one to eight pairs of data called lanes. MIPI supports a complex protocol that allows high speed and low power modes, as well as the ability to read data back from the display at lower rates. There are several versions of MIPI for different applications, MIPI DSI being the one for displays.

Display components stretch the limitations of bandwidth. For perspective, the most common internet bandwidth in a residential home runs on average at around 20 megabits per second or 20 billion 1s and 0s per second. Even small displays can require 4MB per second, which is a lot of data in what is often a tightly constrained physical space.

Take the same PMOLED display with the 128 x 128 resolution and 16,384 separate diodes; it requires information as to when and how brightly to illuminate each pixel. For a display with only 16 shades, it takes 4 bits of data. 128 x 128 x 4 = 65,536 bits for one frame. Now multiply it by the 60Hz, and you get a bandwidth of 4 megabits/second for a small monochrome display.
