Notebook HP HSTNN-IB20 Laptop Battery display is one of the key hardware, accounting for about a quarter of the cost. However, some friends may display on notebook LCD and LED type not quite understand the advantages and disadvantages, this paper specifically explain the difference.
One, LCD and main features of the classification
LCD is liquid crystal display name, the main TFT, UFB, TFD, STN and other types of liquid crystal display.
Commonly used in notebook HP 403808-001 Laptop Battery LCD screen is TFT. TFT screen is thin film transistor, which is an active matrix type liquid crystal display, set back in its special fluorescent tubes can take the initiative on the screen to control each individual pixel, which is the so-called active matrix TFT origin, thus greatly improved response time, about 80 milliseconds, to effectively improve the STN (STN response time of 200 ms) flashes blurred, effectively improve the ability to play moving images. And STN compared, TFT has excellent color saturation, reducing power and higher contrast, the sun is still very clear to see, but the drawback is more power and higher cost.
Second, LED classification and major special
LED is the acronym for light-emitting diode LightEmittingDiode. LED applications can be divided into two categories: First, single-tube LED applications, including the backlight LED, infrared LED, etc.; The other is the LED display.
At present, the basic materials in the manufacture of LED, there are still some international gap, but LED display, China's basic design and production technology with international standards. LED display is formed by the light-emitting diodes arranged in a display. It uses low-voltage scan driver, with: power consumption, long life, low cost, high brightness, less failure, view big, visible from far away and so on.HP HSTNN-IB09 Laptop Battery
Third, LCD and LED main difference
Compared with LCD displays LED displays, LED brightness, power consumption, viewing angle and the refresh rate, etc., have more advantages. LED and LCD power consumption ratio of about 10:1, and higher refresh rate makes the LED in the video have better performance, to provide wide angle of 160 °, you can display a variety of text, numbers, color image and animation information, can also play TV, video, VCD, DVD and other color video signal, multiple displays can be networked broadcast. Single element LED display and speed of response is 1000 times the LCD screen LCD in bright light you can not stop watching, and adapt to the low temperature of minus 40 degrees. Using LED technology, can produce thinner than the LCD, brighter, clearer displays with a wide range of applications.HP 371913-001 Laptop Battery
Simply put, LCD and LED are two different display technologies, LCD is composed of liquid crystal display, the LED is formed by the light-emitting diode display. Compared with LCD displays LED displays, LED brightness, power consumption, viewing angle and the refresh rate, etc., have more advantages.HP HSTNN-DB20 Laptop Battery
Dear friends, after reading the above description, you should understand the difference between LCD and LED bar! Therefore, in the purchase of laptop, be sure to pay attention to the type of display screen to see yo!
