What are the current flat panel display technologies, what are the LCD display technologies What are

At present, the flat panel technology has PDP plasma panel; LCD liquid crystal panel; LED organic light-emitting diode panels and much more.

LCD displays are further divided into: TN-LCD, HTN-LCD, STN-LCD, FSTN-LCD, CSTN-LCD, TFT-LCD, ferroelectric liquid crystal, cholesteric liquid crystal and other liquid crystal display panels.

In terms of features, PDP is mainly used for products above 50 inches, and it should be a large pixel so it can only be used for large-size displays such as TV;

LCD is used in different occasions according to pixel resolution, size, temperature range, panel thickness and so on, 1 inch-50 inch displays can be used, and recently there is an invention of electronic paper, and bendable LCD panels, great.

LED is not very mature now, but the small size can be used in the market, mobile phone screens and notebooks of about 10 inches.

The above is a personal experience, if there is anything inappropriate, please advise.

Wow, that's a lot of questions.

Flat plate: LCD, plasma, LED, OLED;

LCD and plasma can generally be used for household use, and LED is commercial;

OLED is also gradually being promoted;

2) There are many LCD factories, and there are not many that can produce large screens for displays, such as Samsung, BOE, Longteng Optoelectronics, Shanghai Radio and Television, Chimei, etc.

The size is getting bigger and bigger. What technology is used? The principle of liquid crystal imaging.

The LCD production line is divided according to the size of the LCD that can be produced.

How many lines are there and how much capacity is there per year?

This is up to the manufacturer.

Tired of writing.

Display classification from the early black and white world to the current color world, the display has gone through a long and arduous process, with the continuous development of display technology, the classification of the display is becoming more and more detailed. A CRT monitor is a display that uses a cathode ray tube, which consists of five main parts: electron gun, deflection coils, shadow mask, phosphor and glass shell.

It is one of the most widely used monitors, CRT flat screen display has a large viewing angle, no dead pixels, high color reproduction, uniform chromaticity, adjustable multi-resolution mode, extremely short response time and other advantages that LCD displays are difficult to exceed, and the CRT display is much cheaper than LCD displays. According to the standards of different cracks, CRT displays can be divided into different types of reckless types. According to the size of the classification, from the 12-inch black and white display more than ten years ago to the current 19-inch, 21-inch large-screen color display, CRT has experienced the process from small to large, and now the market is dominated by 14 inches, 15 inches, and 17 inches.

In terms of structure, the LCD screen actually belongs to a flat panel display device, and its basic structure is in the shape of a flat panel. The basic structure of a typical liquid crystal screen (LCD) LCD screen is the most basic three components of the LCD LCD screen and their characteristics: the glass substrate is a float production thin glass sheet with a very flat surface, and there is a layer of ZN203 or SN02 transparent conductive layer on the surface of evaporation, which is the ITO film layer, after processing, a transparent conductive pattern is made, if it is scratched, cut or corroded, it will cause the vacuum device to be completely scrapped liquid crystal material The material of liquid crystal is the main part of the liquid crystal screen, The liquid crystal materials used in different devices are also different, most of the liquid crystal materials are mixed by several or even more than a dozen kinds of single liquid crystal materials, polarizers, polarizers, also known as polarized light, are made of plastic film materials, and a layer of optical pressure sensitive glue can be pasted on the surface of the liquid crystal box, and there is a protective film on the surface of the front polarizer, which should be removed when used.

In terms of the internal structure of the liquid crystal display, we can roughly divide it into two parts: "backlight module" and "liquid crystal panel module". The structure of the liquid crystal display is to convert the image signal you want to represent into electronic signals, and these electronic signals will be converted into tiny pixels on the liquid crystal molecular layer, and then form a state that allows the backlight light to pass through, or to block the light. At this time, each pixel can not only express the change of light and dark, but also add two complex electronic signals of gray scale and hue in order to express the color picture, and there is such a large number of LCD panel pixel groups to form the picture in the LCD display.

The internal structure of the liquid crystal display.

The liquid crystal panel can be encapsulated in the liquid crystal molecular layer in the middle of the two upper and lower glass substrate components of the color filter substrate module (polarizer, color filter, common electrode transparent conductive film) and pixel drive substrate mold (polarizer, thin film transistor, pixel electrode transparent conductive film, guide film) group, and the color filter substrate assembly located above is made up of the polarizer plate, the color filter film layer and the transparent conductive film (common electrode) on the glass substrate, and then the alignment film is processed on the transparent conductive film. The pixel-driven side substrate assembly at the bottom is composed of a polarizer and a transparent conductive film (pixel electrode and thin film transistor) on the glass substrate, and a guide film is processed on the transparent conductive film. On the other hand, the backlight differential light source is a modular structure composed of LED (light-emitting diode) light source, diffuser and diffusion plate.

In general, an LCD panel module is composed of an LCD panel, a driver IC, and a printed circuit board. Generally speaking, the liquid crystal display is an electronic loop control module that outputs imaging from the LCD panel module and converts the LCD display into an electronic number, controlling the light emitted by the LCD panel module through and shading, and the backlight light source module. The LCD display emits bright light from the backlight source at the back, and the bright light is controlled by the voltage of the front LCD panel to control the liquid crystal molecules (to pass light through or block the light) to display a bright and dark image.

Slim and lightweight. It was the advent of liquid crystal displays that made the invention of the laptop possible. Similarly, desktop LCDs are larger and heavier than laptops, but they are nothing compared to the clunky and heavy CRT monitors.

Compared to a 15-inch monitor, CRT monitors generally have a deep slag finger source of close to 50 cm, while Jaws' latest LCD monitor, the NF-1500MA, is less than 5 cm deep. With the change of the view of the consumer and the living environment, people have higher and higher requirements for the volume and weight of household appliances. With its inherent advantage of being thin and lightweight, liquid crystal displays are the most likely to break the monopoly of CRT displays.

Accurately reproduce the image. Or the LCD display adopts a direct digital addressing display mode, which can convert the ** signal output by the graphics card according to the signal level"Address"signal, directly display the shirt type corresponding to the ** signal one-to-one on the LCD pixel on the screen. CRT displays, on the other hand, rely on deflection coils to generate electromagnetic fields to control the periodic scanning of electron beams on the screen to achieve the purpose of displaying images.

Because the trajectory of the electron beam is easily affected by the ambient magnetic field or geomagnetic field, the absolute positioning of the electron beam on the screen cannot be achieved. Therefore, CRT displays are prone to geometric distortion and linear distortion of the picture, which cannot be fundamentally eliminated. This is not the case with liquid crystal displays.

The LCD display can present the picture on the screen without any geometric distortion or linear distortion.

LCD panels are mainly used in:LCD liquid crystal splicing field; household LCD TV field; smart phones, tablets; Automobiles, computer fields

1. LCD liquid crystal splicing field

LCD splicing products are the main application products in the field of industrial-grade display, and its representative product is LCD splicing screen, which is mainly used for various monitoring and indoor display occasions, mainly to meet the needs of users with large-size screens.

The LCD panel is cut from a whole version of the glass substrate, the mainstream size on the market is about 55 inches, if it is too large, it is easy to cause transportation difficulties and damage, so customers who have a demand for large screens can only be spliced together and applied through multiple splicing screen products, so that the effect of a whole display wall can be formed, but the shortcomings of LCD splicing large screens are also obvious, there are physical seams between the screens, and there is an obvious black frame, which affects the visual effect more closely. Therefore, its main application field is still in the monitoring occasions where the requirements for the picture sense are not very strong.

2. Household LCD TV

The largest application market of LCD LCD technology is home LCD TV,This is also the main market of LCD LCD panels,The annual shipment volume has reached more than 60% of the entire panel market,And with the popularity of large size,The data also shows that every year China's TV finished products are increased by about 2 inches,So the trend of the entire household LCD TV is still large-size。

3. Smartphones and tablets

Smartphones and tablets are another major market for LCD liquid crystal in recent years, and their market share has gradually increased every year, but in the rapidly developing mobile phone field, a variety of display screens have appeared, such as the recently popular OLED display screen (from which OLED concept stocks come), and even curved screens.

4. Automobile and computer fields

Intelligent car is a new concept implanted by automobile manufacturers in the past two years, and its main realization method is to control the software equipment of the entire car through the intelligence of the central control large screen to achieve different functions, and LCD liquid crystal technology has been applied to this field, becoming the key to the display of smart cars, and in the daily use of computer products, the vast majority of them are using LCD liquid crystal technology, stability, low power consumption, high brightness and a series of advantages are fully displayed in this field.
