how to see lcd screen in sunlight free sample

Have you ever been at the car wash in the late afternoon, struggling to read the instructions on the display at the pay kiosk? That may be because it was not a sunlight-readable LCD display.

Any character or graphic LCD (not TFT, we will get to that in a bit) that is “positive mode” will be sunlight readable. Positive mode displays will have dark letters on a light background.

However, where regular (transmissive) TFT modules wash out in direct sunlight, a transflective TFT will use the sun to be more visible in brighter conditions.

When display devices are brought outside, oftentimes they face the brightness of sunlight or any other form of high ambient light sources reflecting off of and overwhelming the LED backlight’s image.

With the growth of the LCD panel industry as a whole, it has become more important than ever to prevent the sun’s wash out of displays used outdoors, such as automobile displays, digital signage, and public kiosks. Hence, the sunlight readable display was invented.

One solution would be to increase the luminance of the TFT LCD monitor’s LED backlight to overpower the bright sunlight and eliminate glare. On average, TFT LCD screens have a brightness of about 250 to 450 Nits, but when this is increased to about 800 to 1000 (1000 is the most common) Nits, the device becomes a high bright LCDand a sunlight readable display.

Doing this is an affordable option for enhancement of image quality in the outdoors, including features like contrast ratio and viewing angle, in a common use setting like with phones.

Since many of today’s TFT LCD display devices have shifted to touchscreens, the touch panels on the surface of LCD screens already block a small percentage of backlighting, decreasing the surface brightness and making it so that the sunlight can even more easily wash out the display. Resistive touch panels use two transparent layers above the glass substrate, but the transparent layers can still block up to 5% of the light.

In order to optimize the high brightness of the backlight, a different type of touchscreen can be used: the capacitive touchscreen. Though it is more expensive than the resistive touch screen, this technology is more ideal for sunlight readable displays than the resistive due to its usage of a thinner film or even in-cell technologies rather than two layers above the glass of the display, and therefore, light can pass more efficiently.

However, with this method comes a list of potential problems. Firstly, high brightness displays result in much greater power consumption and shorter battery life. In order to shed more light, more power will be needed which can also consequently result in device overheating which can also shorten battery life. If the backlight’s power is increased, the LED’s half-life may also be reduced.

While in bright exterior light settings, these devices reduce eye strain as the user attempts to view the image on screen, the brightness of the display itself can also cause eye strain, seen as the brightness may overwhelm your eyes. Many devices allow the user to adjust brightness, so this concern is oftentimes not too severe.

A recent technology falling into the sunlight readable display category is the transflective TFT LCD, coming from a combination of the word transmissive and reflective. By using a transflective polarizer, a significant percentage of sunlight is reflected away from the screen to aid in the reduction of wash out. This optical layer is known as the transflector.

In transflective TFT LCDs, sunlight can reflect off the display but can also pass through the TFT cell layer and be reflected back out off a somewhat transparent rear reflector in front of the backlight, illuminating the display without as much demand and power usage from the transmissive nature of the backlight. This addresses both the issues of wash out and the disadvantages of high brightness TFT LCDs in high ambient light environments. Because of its transmissive and reflective modes, this type of device is very useful for devices that will be used outdoors but also indoors.

While it does greatly reduce power consumption, transflective LCDs are much more expensive than high brightness LCDs. In recent years, the cost has decreased, but transflective LCDs continue to be more costly.

In addition to adjustments to the internal mechanics of LCDs, it is possible to make devices more sunlight-readable using surface treatments. The most common are anti-reflective (A/R) films/coatings and anti-glare processing.

Anti-reflective focuses on depositing multiple transparent thin film layers. With the thicknesses, structures, and properties of each individual layer composing the film, reflecting light wavelengths are changed, and thus less light is reflected.

When anti-glare is used, reflected light is fragmented. Using a rough surface as opposed to a smooth one, anti-glare treatments can reduce the reflection’s disruption of the actual image of the display.

Often paired with other methods of creating sunlight readable displays is optical bonding. By gluing the glass of a display to the TFT LCD cells beneath it, optical bonding eliminates the air gap that traditional LCD displays have in them using an optical grade adhesive.

This adhesive reduces the amount of reflection between the glass and LCD cell as well as the reflection of external ambient light. Doing this helps provide a clearer image with an increased contrast ratio, or the difference in the light intensity of the brightest white pixel color and darkest black pixel color.

With this contrast ratio improvement, optical bonding addresses the root issue with unreadable outdoor displays: the contrast. Though an increase in brightness can improve contrast, by fixing the contrast itself, LCD display images in outdoor environments will not be as washed out and will require less power consumption.

Besides the visual display advantages that optical bonding provides, this adhesive improves the display in many other ways. The first being durability, optical bonding eliminates the air gap within the device and replaces it with a hardened adhesive that can act as a shock absorber.

Touch screens with optical bonding gain, accuracy in where the point of contact is between the touch and screen. What is known as parallax, the refraction angle of light, can make it seem that the point of contact and the actual point on the display are different. When the adhesive is used, this refraction is minimized, if not reduced.

The optical bonding adhesive’s elimination of the air gap also protects the LCD from moisture/fogging and dust, as there is no space for impurities to penetrate and remain under the glass layer. This especially helps with maintaining the state of LCDs in transport, storage, and humid environments.

Compiling the various methods of improving LCD screens for sunlight readability, these devices can be optimized in high ambient light settings. An anti-glare coating is applied to the surface of the glass and anti-reflective coatings are applied to both the front and back. The transflector is also used in front of the backlight. These features can result in 1000 Nit or more display lighting, without the excessive power consumption and heat production through a high brightness backlight, consequently allowing for a longer lasting and better performing LCD

Unfortunately, the process of building a reflector inside TFT LCD is complicated and transflective TFT LCD is normally several times higher cost compared with normal transmissive TFT LCD.

To further improve and enhance the qualities of the LCD, LED and cold cathode fluorescent lamp (CCFL) backlights are used. Both these create bright displays, but the LED specifically can do so without as much power consumption and heat generation as compared to the CCFL option. Optical bonding is also applied in order to improve display contrast, leading to a more efficient and better quality sunlight readable display.

Outlined in this section are TFT LCD (Thin Film Transistor Liquid Crystal Display) basic knowledge, including structures, driving methods (Passive Matrix / PMLCD, Active Matrix / AMLCD) and comparison, RGB filters, display mode, generations and production process.

As our society progresses into an overwhelmingly technological state, screens seem to pop up almost everywhere. Behind those glass displays, or flat panel displays, lie hundreds of thousands of complex, tiny devices, controlling the pixels that comprise the overall image we see. Those devices are known as Thin Film Transistors, or abbreviated, TFTs.

A TFT LCD,  or a thin film transistor liquid crystal display, is one of the fastest growing forms of display technology today. The thin film transistor (TFT) is a type of semiconductor device used in display technology to enhance efficiency, compactness, and cost of the product.

LCD has a genetic disadvantage compared to other display technologies: Narrow Viewing Angles.  For the last 40 years, scientists and engineers put a lot of effort to improve LCD viewing angles and made great progress. In this section we will introduce O-Film TFT, MVA (Multi-domain Vertical Alignment) TFT, IPS (In Plane Switching)and AFFS (Advanced Fringe Field Switching) TFT.

Most of TFT LCDs are hard to read under the sunlight. Orient Display offer Sunlight Readable TFT with these approaches: Transflective TFT, Surface Treatment, Optical Bonding.

Orient Display’s Electro-Optical Characteristics contains sections of Optical Measurement System, Viewing Angle Range & Measurement System, Contrast Ratio and Response Time.

VarTech’s high bright sunlight readable LCD monitors and touchscreen displays give users crystal clear images and video in direct sunlight and outdoor applications.

These brightness levels far exceed consumer-grade monitors which typically produce 150 to 350 nits brightness. VarTech’s high bright sunlight readable LCD technology ensures crisp, highly viewable videos and images in direct sunlight and high ambient light work environments.

VarTech’s high bright sunlight readable displays use industrial-grade enhanced LED backlights to increase luminance without increasing heat. Proprietary Enhanced Light Transmission Technology (ELTT) gives our screens exceptional clarity, wide viewing angles, and maximum light reflection. Optical bonding reduces light reflection and increases ruggedness by providing a solid transparent bond between the thin-film-transfer (TFT) LCD screen and the front face of the monitor or touchscreen display.

These light enhancements along with VarTech’s quality construction and rugged mechanical design make our industrial grade high bright sunlight readable display products a superior high bright solution for applications that require clarity, intensity, brilliance, and reliable performance from your monitor or computer.

Imagine you have a candle inside a cube with a total surface area measuring one meter by one meter. The total amount of light coming out of that candle at its source is about “one candela.”

All the light hitting the walls of the cube equals “one nit,” which is technically defined as “one candela per square meter.” Each candle you add to the cube will add another candela of luminosity, or another nit, since the square meter now has more light in it. So, 400 candles would equal 400 nit.Candela = about the light from 1 candle

People have been using the TZ1 to TZ 7 and now to TZ10 with the reflective LCD screens and produced numerous excellent shots in beaches-deserts-snows and all forms of landscape and even from airborne sky diving stunts and from aircrafts in open spaces!

This is nonsense. I can take my LX3 out with no LCD at all (shut off), and keep it at a relatively wide angle and point it generally where I want it, and get some photos I really like, but does that mean I never want to or need to see what I"m shooting? Perhaps that"s your style of shooting, and you"re entirely welcome to it, but don"t start telling others how they need to take photos.

Maybe it"s like a comment I saw over in the Canon forum, from a user who claimed he could see just great under all conditons, he didn"t know why people were complaining. Then he said "even out in bright sunlight I can usually make out enough to get the shot". So, therefore "seeing great" is the same as "making out enough to get the shot". Usually.

Or because there are some really nice photos that have been taken with LCD-only cameras (many of them cropped out because the horizon was way off, or other issues they couldn"t see), we should all just write off all the shots they didn"t get?

Let"s say you"re walking along the trail and a bird lands nearby; you smoothly move the camera up and run it to full zoom, hoping to get a shot before he flits off, then you squint and strain trying to see enough so you can tell if that"s a bird or a leaf on the LCD, and if it"s focused on whatever that is, and as he notices the lens, off he flies and you missed your shot. Smiles and moments are fleeting too, and a photo taken a second late can make all the difference in the world.

Some of us like to compose our shots as we shoot, not behind a computer. Some like to have a specific subject in focus, not necessarily what the camera picks the first time. Some might want to shoot directly into a setting sun and see what they"re shooting and how it"s exposed. Some like level horizons, and if you"ve ever shot 16:9 and gotten a crooked horizon, you know how severely you have to crop to clean it up. Some want to catch a smile instead of hoping they"re catching a smile. Some can see clearly at 4" away, some can"t. Some use camera phones and are happy with it, and some aren"t.

If this sounds a little impatient, it"s because I"ve heard it too many times before, and it"s a very narrow-minded view that basically says "this is how I shoot, I"m happy with it, and you can learn to do it too."

I may be happy with point and hope for candid street shooting, because there it makes sense; but that"s only one small part of photography, and there"s nothing wrong with wanting to be able to see what you"re shooting, clearly and easily. To say someone can "learn" to see what they can"t physically see, and should just quit complaining and do it like you do it is pretty presumptious.

This is a common enough problem which has only one real solution: try to film with the sun to one side, rather than behind you, perhaps shading the screen with a free hand.

If you have an articulated screen, turn it so that you get some shade. If the sun is overhead, for example, tilt the screen down a little: the viewing angle on most handycams is wide enough that you don"t need to be looking squarely at it and you"ll actually see the image more clearly.

Obviously if you have an optical viewfinder you can use that, but in general this is a problem as old as photography itself, and the reason photogrpahers used to stand with cloths over their heads! I"m not suggesting you have to do that, but it would actually be a pretty good solution... :smileygrin:

Our high bright monitors are used in uncontrolled lighting environments, we add customized passive enhancements to maximize the contrast and brightness of the touchscreen interface. Anti-glare coating on the face of the touchscreen, and anti-reflective coating on both sides of the LCD. These coatings mirror the index of refraction to reduce light reflecting back at the operator which enhances overall readability and increases the contrast ratio in high direct light and high ambient light environments.

A normal LCD will turn black when exposed to sunlight and UV radiation. Design innovations allow the LCD to operate in direct sunlight. Through the use of these special coatings, films, and filters, the unit obtains sunlight readability without additional backlights. The end result is 1000+ nit equivalent viewing without the additional power draw and heat generation of more backlights. Consequently, our flat panel display systems have longer life, better processor performance, and wider operating temperature range.

AbraxSys integrates enhanced backlight technology increasing the overall luminace output of the LCD’s light source. AbraxSys utilizes both LED and CCFL back lighting technology to achieve higher nit levels at the most efficient consumption levels required for your application. LED yields an amazingly bright LCD panel as does CCFL but with lower power consumption while creating less heat than typically associated with higher watt CCFL back lights. AbraxSys’ high bright LCD monitors bring high bright levels of luminance as well as reliable, efficient design, resulting in unmatched image clarity.

LED combned with optic film stacking, reflection pattern technology, and special radiation technology to maximize the brightness and further limit power consumption. The high bright solution increases day-time and night-time visibility and is the most trusted sunlight readable solution. Typical examples of our high bright monitors in application are ATM screens, the in-vehicle mounted LCDs, the oil rig platforms, and outdoor signage displays.

The VMOB-17B-36 is an optically-bonded 17″ daylight viewable monitor. We design it for use as an outdoor display in indirect sunlight. It is also recommended for indoors where high ambient light decreased the view-ability of standard LCD monitors. The VMOB-17B-36 features a 4:3 aspect ratio. Additionally, this 17″ outdoor monitor display features an extremely wide operating temperature range. It has rear VESA mount holes, and our 3 year warranty.

Some monitors have a sheet of glass over the LCD panel. This protects the panel from accidental or intentional damage. However, the glass also produces unwanted glare and reflections. Internal reflections in the air gap between the glass and the LCD panel diminish image quality even further. In order to combat this, monitors are optically bonded.

Optical bonding is the process of laminating protective glass or a touch screen panel to the LCD panel. An optical-grade resin is inserted between the glass and LCD. This completely fills the air gap. It will not only eliminate the internal reflections, but increase the contrast ratio. This makes the screen much more viewable in bright light conditions. Optical bonding will also eliminate internal moisture and condensation. Moreover, it will make the monitor more rugged and durable. Lastly, an Anti-Reflective coating is applied to the outside of the glass. Consequently, this will drastically reduce glare and surface reflections.

Optical bonding ensures monitors will be highly viewable in bright, indirect sunlight. If sunlight is falling directly onto the face of the monitor, our SRM or SX Series of Sunlight Readable monitors would be most advantageous. Our Sunlight Readable monitors provide 1,000 nits to 2,500 nits brightness. They are for use in direct sunlight.

This article is a part of a Tech Expert Interview with Rei Tjoeng from Sharp Devices: The Market Is Now Shifting To Large-Size TFT Displays In The Automotive Segment

More brightness and higher contrast make the display clear even during bright sunlight conditions. Manufacturers have enormously brought down surface reflectivity with anti-reflective coatings, making the display easier to pursue during high-sunlight glare conditions. Progressive Super View Technology of Sharp, for example, gives an extremely crisp image under sunlight without pumping more power from the backlight, which helps in maintaining the life and quality of the product.

Auto displays range from 3.8cm to more than 30cm. There’s a trend toward bigger display sizes (up to 61cm), with the reception of solid-state and advanced digital clusters. Thus, HD resolution is moving from wide VGA (800×480) to 720p and 1080p.

In the automotive sector, the most common aspect ratio for display sizes between 17.8cm and 31.4cm are 16:9, 5:3, 16:9, and 16:6. From hatchback, sedan to SUV, the height varies a lot and, therefore, aspect ratio plays a vital role for display selection. Recent innovations like Free Form help automotive designers to break free from the rectangle to any size or any form factor of the display. The device may be shaped to fulfil a large range of user needs due to the incorporation of IGZO technology and proprietary circuit design methods.

Conventional displays are rectangular because they require a minimal width for the bezel so as to accommodate the drive circuit, called the gate driver, around the perimeter of the screen’s display area. With the morpheme display (using IGZO technology), the gate driver’s function is dispersed throughout the pixels on the display area. This enables the bezel to be shrunk considerably, and it gives the liberty to style the LCD to match whatever shape the display area of the screen has to be.

Low-voltage differential signalling (LVDS) could be a popular choice for giant LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is most ordinarily utilised in automotive TFT applications. It’s an excellent solution due to its high speed of data transmission while using low voltage.

Two wires carry the signal, with one wire carrying the precise inverse of its companion. The electrical field generated by one wire is neatly concealed by the opposite, creating much less interference to nearby wireless systems. At the receiver end, a circuit reads the difference (hence call Differential) in voltage between the wires. Therefore, this does not generate any 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 a few ground wires.

Centre-stack displays should be visible to both driver and the passengers, including those on the rear seats. LCD display modules are designed to provide the best contrast and readability in one of the four directions, known as the Viewing Angle or Optimal Viewing Direction. These four directions are laid out in the shape of a clock. The top view is at 12:00pm and the bottom view is at 6:00pm.

Optical bonding is the method involving overlaying touchscreens, glass, or plastic cover lenses, adding EMI filters and other display upgrades to an LCD. A layer of glue is incorporated between the cover layer and display to fill the air gap abandoned in a regular edge or gasket bonding. Optical bonding helps in enhancing clarity, viewability, reducing reflections, and making TFT more rugged, which are critical factors in automotive applications.

Temperature range can typically span from -40°C to 85°C. Such a high-temperature range is required because in summer ambient temperature adds up with the operational temperature of TFT, where normally in desert areas ambient temperature rises to 55°C in summer.

Turn the panel over so that you"re working on the front of the panel. Place the panel on a book or the edge of the table, so that the pins hang over the edge and don"t get damaged while you"re working on the panel.

Select the top film and orient the film so that the arrow on the film label points to the side of the panel with the pins, then peel the protective film layer off the bottom film. This is the side with the sticker.

Peel the adhesive release film away from one edge and apply that edge of the film to the top of the panel panel and press it down with your finger. Gradually peel back the adhesive release film and use the card or roller to work the air out from under the film. If you see an air bubble form, gradually lift the film past the bubble and then reapply.

Use the razor blade to trim the film to the left and right sides and the bottom of the panel. If the film hangs over the top of the viewable area of the panel, that"s fine, but do not try to trim it from the top side, as the IC and conductive traces are easily damaged.

Remove the white backing from the factory graphics and align the bottom edge to the panel. Make sure that the graphics are evenly spaced on the polarizing film. There should be approx 1/32" gap between the bottom side of the panel and the start of the black border.
