>> BOE AMQLED products and LCD, AMOLED compared to any advantage? 27th,Nov,2017
Recently, BOE successfully developed a 5-inch active quantum dot light-emitting display product (AMQLED), which is the result of a research project undertaken by BOE under the State Key Research and Development Program of Ministry of Science and Technology entitled "Research on Key Quantum Dot Display Materials and Devices".
In the LCD, OLED, AMOLED, PMOLED panel has been dazzling variety of circumstances, the BOE launched an AMQLED, then these screens, in the end what are the characteristics of each day we are using daily use of the phone is what screen What?
AMOLED, PMOLED are OLED
OLED English name is Organic Light Emitting Diode, translated into organic light-emitting diode. Organic refers to the organic, that is, between the positive and negative time using a series of organic thin-film materials, so as to achieve the purpose of emitting light.
OLED has the advantages of self-luminous, wide viewing angle, high contrast ratio, low power consumption, high response rate, full colorization, simple manufacture and so on, so it is regarded as the next generation display technology. International panel makers such as Samsung and LG all attach great importance to OLED technology .
OLED according to the drive classification, can be divided into
AMOLED
PMOLED
The difference is that one is active control light, one is passive control light. AMOLED English full name is Active Matrix Organic Light Emitting Diode, meaning active matrix organic light-emitting diode. The PMOLED English full name Passive Matrix Organic Light Emitting Diode, meaning passive matrix organic light-emitting diode. PMOLED using scanning method, you need to instantly generate higher brightness, and high power consumption. In addition, PMOLED display device is more aging, life cycle is shorter. More critical is that this technology is not suitable for large-size high-resolution screen.
AMOLED consists of OLED and driver. A thin film transistor and a capacitor layer are added to each LED to control the brightness of the OLED to achieve faster and more accurate pixel lighting control. Compared with the PMOLED, AMOLED more advantages in energy consumption, display quality and life cycle, but also in large-size panels, AMOLED also more advantages.
Therefore, AMOLED more and more popular, commercial demand has also increased in about five or six years ago AMOLED output has surpassed PMOLED. Today, Samsung, LG panel production capacity will be turned to OLED, everyone's first reflection is Samsung, LG converted AMOLED panel.
LCD and OLED which one is better
At the end of 2015, BOE invested 40 billion yuan in Hefei to build a 10.5-generation thin film transistor liquid crystal display (TFT-LCD) production line for the production of large-size ultra-high definition liquid crystal displays of 65 inches and above. In the domestic situation is still investing in LCD, Samsung and LG have some production line capacity into OLED. So, LCD and OLED in the end what are the advantages and disadvantages?
LCD's structure is a little bit similar to the sandwich, the upper and lower glass substrate, the middle is a thin film transistor and color filter, through the TFT signal and voltage changes to control pixel display. LCD LCD panel has several branches, such as relatively high-end and display better IPS, AFFS and so on.
The LCD panel branches display different details, but essentially all behave differently depending on the optical polarization of the liquid crystal and the specific spectral absorption (selective pass) of the backlight. However, due to polarization filtering, the light source efficiency of the LCD is at least halved, and the spectral characteristic and brightness of the backlight directly affect the display effect.
