lcd display structure pricelist

The LCD display module is a type of display used in digital clocks and many portable computers. It uses two pieces of polarized material with a liquid crystal solution between them. The LCD display module is a very delicate thing, which has many advantages such as low power consumption, no radiation, no dizziness, and so on. And it protects the eyesight of the user to a great extent. With the development of liquid crystal display technology and the continuous decline of liquid crystal prices, today"s liquid crystal display has become a must-have electronic product for many people. So what are the components of the LCD screen?

The LCD panel is commonly known as glass. It is the most important core component of the LCD display module. The quality of a display mainly depends on the quality of the LCD panel, which directly affects the sensory experience of the screen. The LCD panel is generally produced as a large board, which is cut into small boards according to different sizes and becomes a core component.

The backlight refers to the light source behind the LCD display module. Without the light source, the display screen will not have any display. The components of the backlight are composed of the light source, the light guide plate, the optical film, and other structural parts. The backlight can control the brightness according to the lamp beads and power consumption. If you need high brightness, you can change it according to the structure of the backlight. Of course, you cannot turn up the screen without a limit. The degree of its brightness is designed based on the internal structure and power consumption of the whole machine.

FPC flexible circuit board, which is a flexible circuit board with high wiring density, lightweight, thin thickness, and good bendability. The LCD display module conducts electricity through the FPC to realize the display function. It is also an important component that is indispensable. Of course, FPC is not the only conductive component. Some large screens are energized through USB and other interfaces. FPC is a common conductive component for small and medium-sized LCD display modules.

IC is what everyone often says. A chip is a kind of miniature electronic device or component. It uses a certain process to interconnect the transistors, diodes, resistors, capacitors, and inductors, and other components and wiring required in a circuit to make a small piece. Or a few small pieces of semiconductor wafers or dielectric substrates, and then packaged in a package to become a miniature structure with the required circuit functions. With it, any function can be realized.

The LCD display module has strict requirements on air humidity, so it must be able to work in a relatively dry environment. In particular, moisture cannot be brought into the interior of the display screen, so this is particularly critical for some users whose working environment is relatively humid. If there is water in the LCD screen, what you need to do is place it in a dry place to allow the water to evaporate. Do not turn on the power rashly at this time. Otherwise, the LCD electrodes of the screen will be corroded, causing liquid crystal damage to the display.

Photo: Prove to yourself that an LCD display uses polarized light. Simply put on a pair of polarizing sunglasses and rotate your head (or the display). You"ll see the display at its brightest at one angle and at its darkest at exactly 90 degrees to that angle.

To create an LCD, you take two pieces ofpolarized glass. A special polymer that creates microscopic grooves in the surface is rubbed on the side of the glass that does not have the polarizing film on it. The grooves must be in the same direction as the polarizing film. You then add a coating of nematic liquid crystals to one of the filters. The grooves will cause the first layer of molecules to align with the filter"s orientation. Then add the second piece of glass with the polarizing film at a right angle to the first piece. Each successive layer of TN molecules will gradually twist until the uppermost layer is at a 90-degree angle to the bottom, matching the polarized glass filters.

If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas.

Building a simple LCD is easier than you think. Your start with the sandwich of glass and liquid crystals described above and add two transparent electrodes to it. For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it. The layers would look like this:

The LCD needed to do this job is very basic. It has a mirror (A) in back, which makes it reflective. Then, we add a piece of glass (B) with a polarizing film on the bottom side, and a common electrode plane (C) made of indium-tin oxide on top. A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D). Next comes another piece of glass (E) with an electrode in the shape of the rectangle on the bottom and, on top, another polarizing film (F), at a right angle to the first one.

The electrode is hooked up to a power source like a battery. When there is no current, light entering through the front of the LCD will simply hit the mirror and bounce right back out. But when the battery supplies current to the electrodes, the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle untwist and block the light in that region from passing through. That makes the LCD show the rectangle as a black area.

Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full-motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market prices and arrival/departure display times. The cathode ray tube was the workhorse of text and video display technology for several decades until being displaced by plasma, liquid crystal (LCD), and solid-state devices such as thin-film transistors (TFTs), LEDs and OLEDs. With the advent of metal–oxide–semiconductor field-effect transistors (MOSFETs), integrated circuit (IC) chips, microprocessors, and microelectronic devices, many more individual picture elements ("pixels") could be incorporated into one display device, allowing graphic displays and video.

One of the earliest electronic displays is the cathode ray tube (CRT), which was first demonstrated in 1897 and made commercial in 1922.electron gun that forms images by firing electrons onto a phosphor-coated screen. The earliest CRTs were monochrome and were used primarily in oscilloscopes and black and white televisions. The first commercial colour CRT was produced in 1954. CRTs were the single most popular display technology used in television sets and computer monitors for over half a century; it was not until the 2000s that LCDs began to gradually replace them.

A derivative of CRTs were storage tubes, which had the ability to retain information displayed on them, unlike standard CRTs which need to be refreshed periodically. In 1968, Tektronix introduced the Direct-View Bistable Storage Tube, which went on to be widely used in oscilloscopes and computer terminals.

1968Direct-View Bistable Storage Tube CRT retains static information displayed upon it, written using a steerable electron beam that can be turned off. The DVBST was used in vector displays of early computers and in oscilloscopes.

1984 Super-twisted nematic display (STN LCD) to improve passive-matrix LCDs, allowing for the first time higher resolution panels with 540x270 pixels.

A medical display is a monitor that meets the high demands of medical imaging. Medical displays usually come with special image-enhancing technologies to ensure consistent brightness over the lifetime of the display, noise-free images, ergonomic reading and automated compliance with DICOM and other medical image quality standards.

A diagnostic display for radiology and/or mammography is used by radiologists to view diagnostic images, such as X-rays, MRIs, CT scans and more. These displays come with special tools and technologies to help radiologists make a swift and accurate diagnosis.

Digital mammography images require the highest resolution and brightest displays for review. Higher brightness can contribute to a bigger chance of finding microcalcifications, which could indicate presence of breast cancer.

Displays for digital pathology are designed especially for image viewing in pathology. For example, they offer color spaces that are adapted to digital slides, or fast refresh rates for smooth and clear images during panning or zooming. They deliver consistent, detailed images and their image quality doesn’t degrade over the years.

Medical displays for radiology, mammography and pathology require an advanced display controller that can faultlessly process the large, highly detailed files that come with medical imaging. They can handle intensive, long-term use, and process large images correctly and with minimal delay. In these ways, they can support the medical professional’s workflow. Furthermore, advanced display controllers can support technologies to better detect small details and work faster.

Surgical displays range from near-patient monitors to large-screen OR displays. Most surgical displays can be mounted onto surgical arms or booms, with cables neatly hidden, and the screen is usually scratch-resistant. They can also allow for easy cleaning and disinfection.

A dental display is a high-bright, medical monitor designed for viewing of dental images, such as X-rays of teeth, bone, nerves, and soft tissue. With dental displays, subtle abnormalities or concealed anatomical structures in the oral and maxillofacial regions become more visible, compared to consumer displays. This makes it easier for dentists to detect dental pathologies. Dental displays come in various shapes and forms, from cleanable review displays to high-end displays designed specifically for dental diagnosis.

You don’t always need a high-resolution diagnostic display in a clinical environment. You might be looking for a display you can use for various non-diagnostic activities, such as enabling easy access for clinical staff to electronic medical records, or medical images. Clinical review displays help you making medical information available across an enterprise, reliably and with consistent image quality. They can offer additional functionalities for use in medical environment, such as cleanable design that can stand alcohol cleaning agents. All our clinical review displays are DICOM-compliant.
