museum touch screen monitors made in china

At present, LED screen display is in the stage of development and growth. With the continuous development and maturity of LED display technology, in addition to traditional indoor and outdoor fixed installation and rental LED screen, many market segments have been derived, such as floor led screen, football field screen, creative led screen etc. The appearance of the creative LED screen is the inevitable result of the development and maturity of LED display technology.

A touchscreen media kiosk developed for museum patron interaction and information display. The screen angle is adjustable to allow for users of all heights.

When autocomplete results are available use up and down arrows to review and enter to select. Touch device users, explore by touch or with swipe gestures.

Touchsceeen technology is now commonplace in our daily lives with applications ranging from a taxi ride, to a restaurant visit or a boardroom meeting.

Interactive displays continue to transform the landscape all around us, this is especially apparent in environments which are customer focused. In this blog we take a look at the uses of touch screen digital signage in Museums and similar visitor attractions.

Information display areas for museums or galleries are ever changing as new installations, exhibitions, talks and demonstrations are introduced throughout the year. With digital signage, the latest information can be conveyed without the need to redesign or rebuild traditional signage.

Attracting younger visitors and a new generation of potential donors or volunteers is an increasing challenege for museums and galleries alike. In recent years, the decline of visitor levels of cultural attractions for younger demographics is evident, and creating a more interactive experience through technology is a measure proving very effective.

Cooper Hewitt recently reopened after a comprehensive $81 million, three-year renovation, which has transformed their 64-room mansion into an innovative, technologically advanced museum and gallery.

Zytronic provided the touch solution forIdeum who designed and developed a custom 4K UHD 84” and 55” multitouch tables for the design museum.  Working together to design the 84” 4K interactive screen, the goal was to enable high fidelity multi-user multi-touch and stylus interaction.

The touch tables feature multi-touch projected capacitance based touch sensors, which are made from thermally toughened glass, which  provides a strong resilience to severe impacts, scratches and liquid spillages.  The high performance multi touch technology also eradicates the risk of ‘false’ touches from coat sleeves and bottles for example, as the embedded touch controller can detect and ignore touches from non-conductive items.

The touch tables also have built in NFC stations which allow visitors to check in with a specialised stylus pen.   Featuring in a gallery on the history of wallpaper, the touch table is used by visitors to browse hundreds of designs, as well as designing their own wallpaper.

In an attempt to attract declining museum visits from those aged 35 to 45, other museums are watching the success of the Cooper Hewitt revamp closely.  Distributing interactive devices or offering touch display areas as part of an exhibition is a growing trend that any Museum director will be keen to adopt.

Over the years, a wide range of Pro Display’s products have been specified for museums. For a number of reasons, many products that Pro Display offer are ideal for creating some of the best museum displays possible, from interactive projection touch screens that make up entire displays, to supporting screens that supplement a museum exhibit display, it is quite probable that Pro Display offer a product that will suit, and often even surpass your museum display needs.

As the technological landscape changes, so do desired display solutions and the transition from printed to digital signage has been a huge step in this direction. Few industries feel this transition as keenly as museums, who often rely heavily upon signage to direct and inform visitors. Indeed, for museums, signage makes up a significant part of their experience, so the media that is used for this central aspect of business is highly important for the general customer as well as the organisation’s reputation.

An effective museum display can take on many forms, from a high brightness screen to contend with ambient light to an interactive freestanding kiosk for self-service or self-educating means. The uses of all these technologies within a museum environment also varies drastically, such as being used for wayfinding, as part of a museum exhibit display, or even the exhibit itself – the applications are only limited by the choice of technology. Luckily, Pro Display have many years of experience working with museums and designers to help supply them with the best museum displays available using the most cutting-edge technology on the market.

A great example of a cutting-edge product that is becoming increasingly popular in museums is Pro Display’s Transparent LCD Display Cases. These breath-taking visual marvels offer an effective, backlit display unit that overlays white content as transparent on the screen. Using this feature creatively, museums can virtually eradicate the need for additional exhibit space, combining the display case and supporting screen into one unit. Ideal for displaying high value or fragile items out of reach, Transparent LCD display cases are a great way to impress visitors using a museum display that is as effective at communicating information as it is building excitement in, for example, a reveal and conceal exhibition application.

Likewise, Switchable Smart Glass technology offers a highly effective reveal and conceal privacy product, serving as frosted glass that changes to clear on command. Using various activation methods, such as voice or sensor, museums can tailor this technology to suit their exacting needs, enhanced with various glass options as well as the retrofit Self-Adhesive Smart Film as available possibilities. Combine this with the option of using this amazing glass as a projection screen and the applications become a lot more exciting than a basic reveal and conceal application.

However, perhaps the most popular development in recent years has been museum touch screen displays, which are widely used in these environments due to their interactive nature. Using Pro Display’s intouch range, most display options can be granted interactivity, including the above-mentioned Transparent LCD Display cases and Switchable Smart Glass. People often peruse museums at their own pace and therefore a self-service interactive display can be a highly effective tool for the interested and meandering visitor alike. A touch screen display allows museums to offer visitors infinitely more information, more entertainment and more control over the way and pace that they digest this information when compared to traditional signage. It is little wonder, therefore, that touch screens are becoming a central part of the museum experience.

Visual effects are also highly popular in this environment due to the on-going challenge of creating a memorable museum display. Specialist visual effects are a great way to immerse visitors who crave a new experience that they can take away with them. Offering a memorable visual experience can help to drastically change the way exhibitions are perceived and is a cornerstone of the museum model. Visual effects can also help museums respond to challenging environmental conditions such as high ambient light or reduced space.

A very popular choice for museums, Pro Display’s Holographic Effect Projection Screens provide a floating image visual effect. Also known as ‘Pepper’s Ghost’ effect, this technology is ideal for creating effective ghostly images to re-tell stories of their history, for example. Alternatively, using this screen for hi-tech or hologram-styled displays is also incredibly powerful. As a semi-transparent projection screen, these displays can show bright, sharp and vibrant 2D images that appear to float as an Iron Man-styled hologram, with superior performance, definition and no critical angle of projection to boot.

Due to the remarkably visual aspect of the museum experience, high ambient light is often a requirement of the environment so that visitors can clearly see what is on display. However, this can often clash with the high reliance on digital signage displays seen by museums. Many forms of digital signage can be affected by the glare often associated with environments that suffer from high levels of ambient light; Pro Display offer a range of products that can help combat this. Depending on the nature of the high ambient light and the technological requirements, the range of products are vast enough to help combat this for most applications. A High Brightness LCD Screen, for example, offers an effective alternative to standard LCD signage in areas of high ambient light. An Ambient Light Rejecting (ALR) Projection Screen, at the same time as rejecting ambient light and displaying images with stunning contrast, colour and resolution, also offers the ability to edge blend using a UST projector, which enables uniquely shaped and intriguing displays. Our Anti-Glare options, on the other hand, are a retrofit based product that helps existing screens deal better with glare so museums don’t have to change their exhibit too much to accommodate high ambient light.

As an ultra-short throw (UST) projection screen, Digital Glass offers museums an incredible space saving display solution that delivers high brightness and unparalleled contrast in brightly lit environments without creating hotspots. Ideal for professional, high quality displays, these screens provide a robust digital signage and exhibition solution that are great for large format projection, simulation applications and even as an alternative to video walls. The polished edges of these rigid screens enable multiple panels to be installed side-by-side, allowing designers to create huge seamless screens without bezels. Factoring in the ability to convert these screens to accommodate 3D and edge blending, they are perfect for simulation or CAVE projection applications that require visitor immersion, so it seems obvious that they would perform exceptionally well in a museum environment.

A three-year project to restore and conserve one of the rarest and most valuable works in the Tyler Museum of Art’s Permanent Collection is complete, with the recent return of a pair of 18th century folding screens by Japanese painter Soga Shohaku.

The museum is presenting the newly restored work to the public for the first time in several years with a special exhibition, “Soga Shohaku: A Chinese Landscape,” through July 28 in the Education Gallery.

“Soga Shohaku: A Chinese Landscape” depicts a mythical Chinese landscape on two large, recently restored 18th century Chinese screens. They are on view through July 28 at Tyler Museum of Art. (Courtesy).

The six-fold ink-on-paper screens, each more than 5 feet high and 11 feet in length when fully expanded, depict a mythical Chinese landscape and collectively are titled Chinese Landscape.

The screens were created in approximately 1770 by Shohaku (1730-1781), a painter of Japan’s Edo period who worked primarily in the brush style of the Muromachi period. This distinguished the painter from his contemporaries, as the Muromachi aesthetic was considered outdated more than a century before Shohaku’s birth.

Tyler Museum of Art acquired the screens in 2007 as a gift from Julietta Jarvis, an East Texas philanthropist and former mayor of Troup, who was a longtime supporter of the TMA.

Jose served from 1990-95 as the chief conservator for Asian prints and paintings at the Honolulu Museum in Hawaii and is founder of the Druk Foundation for Art Preservation and the Thangka Conservation Center in Thimphu, Bhutan.

The museum is located at 1300 S. Mahon Ave. and is open 10 a.m. to 5 p.m. Tuesday to Saturday and 1 to 5 p.m. Sunday. It is supported by its members, Tyler Junior College and the city of Tyler.

Emperor Kangxi and Emperor Qianlong in their court dress debuted in two of our specially designed museum grade wall display cases ​in 2011. After three and a half months of hard work, the two  display panels measuring 3W x 5H x 0.7D m were installed in the National Museum Of China

Two paintings of the court dresses of Kangxi Emperor and Qianlong Emperor were painted by Giuseppe Castiglione (1688-1766), with an overall dimension of 3m (Length) x 5m (Height) x 0.7 (Thickness), were exhibited in the Ancient China hall, National Museum of China. In order to present the paintings in the closest proximity to viewers, a single piece of glass weighing 612.7Kg was used, which posed a great challenge in the design of the overall structure of the panels. The mainframe of the panel is made of a 27mm-thick steel plate to support the 612.7kg load and protect the displayer from distortion after long-term use. The electric opening system ensures added safety. The electric lifting system makes it convenient to reposition the painting at the ground level. The TCFA system centrally controls all functions. The magnetic display system of the rear dress panel within the displayer helps with the flattening of the exhibit. This system reduces the possible strain and damage caused by gravity to fibrous materials which are hung and displayed vertically.

The EX Future and Science Museum in the Chinese city of Dalian shows off advanced forms of robotic technology aimed at making robots as customizable and lifelike as possible.

According to a tour of the museum"s research and design center published by the Chinese state-linked media channel CGTN, the technicians at the museum can scan features and limbs to create dynamic 3D robots.

The museum"s robots have also ventured outside of its compound. In a video uploaded to Facebook in November, one of the museum"s robots wears a face shield and guides people to COVID-19 test sites in Dalian.

The museum, which opened in September 2021, also features robots modeled after Albert Einstein and Steve Jobs. The two robots are featured in a promotional clip for the exhibit uploaded in February, waving and wishing visitors a joyous Chinese New Year.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).

The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko"s R&D group began development on color LCD pocket televisions.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.compact, full-color LCD projector.

Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain the dominant LCD designs through 2006.South Korea and Taiwan,

EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special glass is used when the thickness of the LCD is of primary concern, because it doesn"t expand as much when heated or exposed to moisture, which allows LCDs to be just 5mm thick. Quantum dots may be placed on top of the diffuser as a quantum dot enhancement film (QDEF, in which case they need a layer to be protected from heat and humidity) or on the color filter of the LCD, replacing the resists that are normally used.

WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel. LCDs that use this implementation will usually have the ability to dim or completely turn off the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display. The precision with which this can be done will depend on the number of dimming zones of the display. The more dimming zones, the more precise the dimming, with less obvious blooming artifacts which are visible as dark grey patches surrounded by the unlit areas of the LCD. As of 2012, this design gets most of its use from upscale, larger-screen LCD televisions.

Today, most LCD screens are being designed with an LED backlight instead of the traditional CCFL backlight, while that backlight is dynamically controlled with the video information (dynamic backlight control). The combination with the dynamic backlight control, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan, simultaneously increases the dynamic range of the display system (also marketed as HDR, high dynamic range television or FLAD, full-area local area dimming).

Due to the LCD layer that generates the desired high resolution images at flashing video speeds using very low power electronics in combination with LED based backlight technologies, LCD technology has become the dominant display technology for products such as televisions, desktop monitors, notebooks, tablets, smartphones and mobile phones. Although competing OLED technology is pushed to the market, such OLED displays do not feature the HDR capabilities like LCDs in combination with 2D LED backlight technologies have, reason why the annual market of such LCD-based products is still growing faster (in volume) than OLED-based products while the efficiency of LCDs (and products like portable computers, mobile phones and televisions) may even be further improved by preventing the light to be absorbed in the colour filters of the LCD.

A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form a grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed for a 1080p display is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That"s three for red, green and blue and 1920 columns of pixels for each color for a total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge.

The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB (Tape-automated bonding) These same principles apply also for smartphone screens that are much smaller than TV screens.anisotropic conductive film or, for lower densities, elastomeric connectors.

A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.

High-resolution color displays, such as modern LCD computer monitors and televisions, use an active-matrix structure. A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor, allowing each column line to access one pixel. When a row line is selected, all of the column lines are connected to a row of pixels and voltages corresponding to the picture information are driven onto all of the column lines. The row line is then deactivated and the next row line is selected. All of the row lines are selected in sequence during a refresh operation. Active-matrix addressed displays look brighter and sharper than passive-matrix addressed displays of the same size, and generally have quicker response times, producing much better images. Sharp produces bistable reflective LCDs with a 1-bit SRAM cell per pixel that only requires small amounts of power to maintain an image.

In-plane switching is an LCD technology that aligns the liquid crystals in a plane parallel to the glass substrates. In this method, the electrical field is applied through opposite electrodes on the same glass substrate, so that the liquid crystals can be reoriented (switched) essentially in the same plane, although fringe fields inhibit a homogeneous reorientation. This requires two transistors for each pixel instead of the single transistor needed for a standard thin-film transistor (TFT) display. The IPS technology is used in everything from televisions, computer monitors, and even wearable devices. IPS displays belong to the LCD panel family screen types. The other two types are VA and TN. Before LG Enhanced IPS was introduced in 2009, the additional transistors resulted in blocking more transmission area, thus requiring a brighter backlight and consuming more power, making this type of display less desirable for notebook computers. Currently Panasonic is using an enhanced version eIPS for their large size LCD-TV products as well as Hewlett-Packard in its WebOS based TouchPad tablet and their Chromebook 11.

In 2011, LG claimed the smartphone LG Optimus Black (IPS LCD (LCD NOVA)) has the brightness up to 700 nits, while the competitor has only IPS LCD with 518 nits and double an active-matrix OLED (AMOLED) display with 305 nits. LG also claimed the NOVA display to be 50 percent more efficient than regular LCDs and to consume only 50 percent of the power of AMOLED displays when producing white on screen.

Some LCD panels have defective transistors, causing permanently lit or unlit pixels which are commonly referred to as stuck pixels or dead pixels respectively. Unlike integrated circuits (ICs), LCD panels with a few defective transistors are usually still usable. Manufacturers" policies for the acceptable number of defective pixels vary greatly. At one point, Samsung held a zero-tolerance policy for LCD monitors sold in Korea.ISO 13406-2 standard.

Some manufacturers, notably in South Korea where some of the largest LCD panel manufacturers, such as LG, are located, now have a zero-defective-pixel guarantee, which is an extra screening process which can then determine "A"- and "B"-grade panels.clouding (or less commonly mura), which describes the uneven patches of changes in luminance. It is most visible in dark or black areas of displayed scenes.

Temporal performance: the temporal resolution of an LCD is how well it can display changing images, or the accuracy and the number of times per second the display draws the data it is being given. LCD pixels do not flash on/off between frames, so LCD monitors exhibit no refresh-induced flicker no matter how low the refresh rate.

Color performance: There are multiple terms to describe different aspects of color performance of a display. Color gamut is the range of colors that can be displayed, and color depth, which is the fineness with which the color range is divided. Color gamut is a relatively straight forward feature, but it is rarely discussed in marketing materials except at the professional level. Having a color range that exceeds the content being shown on the screen has no benefits, so displays are only made to perform within or below the range of a certain specification.white point and gamma correction, which describe what color white is and how the other colors are displayed relative to white.

Limited viewing angle in some older or cheaper monitors, causing color, saturation, contrast and brightness to vary with user position, even within the intended viewing angle.

Uneven backlighting in some monitors (more common in IPS-types and older TNs), causing brightness distortion, especially toward the edges ("backlight bleed").

As of 2012, most implementations of LCD backlighting use pulse-width modulation (PWM) to dim the display,CRT monitor at 85 Hz refresh rate would (this is because the entire screen is strobing on and off rather than a CRT"s phosphor sustained dot which continually scans across the display, leaving some part of the display always lit), causing severe eye-strain for some people.LED-backlit monitors, because the LEDs switch on and off faster than a CCFL lamp.

Only one native resolution. Displaying any other resolution either requires a video scaler, causing blurriness and jagged edges, or running the display at native resolution using 1:1 pixel mapping, causing the image either not to fill the screen (letterboxed display), or to run off the lower or right edges of the screen.

Input lag, because the LCD"s A/D converter waits for each frame to be completely been output before drawing it to the LCD panel. Many LCD monitors do post-processing before displaying the image in an attempt to compensate for poor color fidelity, which adds an additional lag. Further, a video scaler must be used when displaying non-native resolutions, which adds yet more time lag. Scaling and post processing are usually done in a single chip on modern monitors, but each function that chip performs adds some delay. Some displays have a video gaming mode which disables all or most processing to reduce perceivable input lag.

Dead or stuck pixels may occur during manufacturing or after a period of use. A stuck pixel will glow with color even on an all-black screen, while a dead one will always remain black.

In a constant-on situation, thermalization may occur in case of bad thermal management, in which part of the screen has overheated and looks discolored compared to the rest of the screen.

Loss of brightness and much slower response times in low temperature environments. In sub-zero environments, LCD screens may cease to function without the use of supplemental heating.

The production of LCD screens uses nitrogen trifluoride (NF3) as an etching fluid during the production of the thin-film components. NF3 is a potent greenhouse gas, and its relatively long half-life may make it a potentially harmful contributor to global warming. A report in Geophysical Research Letters suggested that its effects were theoretically much greater than better-known sources of greenhouse gasses like carbon dioxide. As NF3 was not in widespread use at the time, it was not made part of the Kyoto Protocols and has been deemed "the missing greenhouse gas".
