No, the notebook LCD display is divided into two categories LCD and LEDLCD is often said, is Liquid Crystal Display, the LCD structure is placed in the liquid of two pieces of parallel glass crystal, fine wire and many vertical and horizontal between two pieces of glass, through the power to control the crystal rod the molecular changes of direction, will produce the picture reflected light. Liquid crystal display in accordance with different control methods can be divided into passive matrix LCD and active matrix LCD two. LED display (LED Panel) LED (Light Emitting Diode) led is a solid state semiconductor device, which can directly convert electricity into light. The LED pixel module is assembled and arranged in accordance with the actual needs, arranged into a matrix, and provided with a special display drive circuit, a DC stabilized voltage power supply, a software, a frame and an outer decoration, etc. to form a LED display screen. At present, some of the high-end Apple series is LED screen, more light, more power saving, more realistic. The single element of the LED display is 1000 times faster than the LCD LCD screen, and can be taken care of under high light conditions, and adapts to a low temperature of 40 degrees below zero. Another big advantage of LED is that it can last up to 100 thousand hours, even if it lasts 10 hours a day for 27 years. Laptop LCD screen is the use of CCFL fluorescent tube backlight, due to CCFL life, environmental protection and other adverse reasons, is currently toward the development of LED backlight. According to the size of the LCD screen, generally need dozens to hundreds of white LED backlight, and its LED drive IC market potential will be great.
At present, the laptop is now LCD screen, LCD screen referred to as LCD. There are also a few uses of LED. LCD screen with more, only some small screen books, or higher prices on the books with LED screen. Compared with LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate, etc. LED. Power LED and LCD ratio is about 10:1, and a higher refresh rate so that LED has better performance in the video, can provide up to 160 degrees wide angle, can display a variety of text, numbers, color image and animation information, you can also play TV, video, VCD, DVD color video signal. Multi picture display can also be broadcast network. Organic LED display single element, the reaction speed is 1000 times the LCD LCD screen, in bright light can also take care of error, and adapt to minus 40 degrees of low temperature. Using LED technology, it can make thinner, brighter and clearer display than LCD, and has wide application foreground.
Laptops do not all use liquid crystal displays, typically LCD and CRT displays. The LCD monitor is a liquid crystal display.LCD (Liquid, Crystal, Display) liquid crystal display. The structure of the LCD is placed in the liquid crystal box two parallel glass substrate, glass substrate is provided under the TFT (thin film transistor), on the glass substrate is arranged on the color filter, rotation direction signal and the voltage change by TFT to control the liquid crystal molecules, so as to achieve the control of each pixel or to exit light to display. Now, LCD has replaced CRT as the mainstream, and prices have dropped a lot, and have been fully popularized.CRT is a cathode ray tube (Cathode Ray Tube) display, there are five main components: electron gun (Electron Gun) (Deflection coils), deflection coil (Shadow, mask), the mask of phosphor layer (Phosphor) and glass shell. It was one of the most widely used CRT display, flat panel display with large viewing angle, no dead pixels, color reproduction and high color uniformity, adjustable multi-resolution model, short response time and the like LCD display is difficult to go beyond, and CRT display price before a lot cheaper than LCD monitors.
