TFT (thin film transistor) is the abbreviation of thin film transistor, but actually refers to thin film transistor (color active matrix), which can “actively” control each independent pixel on the screen, Each pixel is divided into RED, GREEN, BLUE dots which are arranged in vertical stripe, which is the origin of the so-called color active matrix TFT.
TFT LCD display is the mainstream display device in all kinds of notebook computers and desktop computers. Such as 13 inch to 15.6 inch usual laptop screen, and some industrial lcd screen 7 inch, 8 inch and 10.1 inch.
TFT display has the advantages of high response, high brightness, high contrast and so on.
TFT LCD need LED backlight.
OLED, namely organic light emitting diode, also known as organic electro-luminesence display (OELD)
The basic structure of OLED is composed of a thin and transparent indium tin oxide (ITO) with semiconductor characteristics, which is connected with the positive pole of power, plus another metal cathode, which is wrapped into a sandwich structure. The whole structure layer includes hole transport layer (HTL), light emitting layer (EL) and electron transport layer (ETL). When the power is supplied to an appropriate voltage, the positive hole and the cathode charge will be combined in the light-emitting layer to produce light.
OLED is characterized by its own light, unlike TFT LCD, which requires backlight.
Thus it has high visibility and brightness. Secondly, it has low voltage demand, high power saving efficiency, fast response, light weight, thin thickness, simple structure and low cost, but micro OLED cost is high.
The Difference of TFT LCD and OLED
Technology: TFT LCD (Thin-Film Transistor Liquid Crystal Display) is a type of LCD technology that uses a backlight and a layer of liquid crystals to create images. On the other hand, OLED (Organic Light Emitting Diode) uses organic materials that emit light when an electric current is passed through them.
Contrast Ratio: OLED displays have a higher contrast ratio than TFT LCD displays. This means that OLED displays are capable of producing deeper blacks and brighter whites, resulting in a more vivid and immersive viewing experience.
Viewing Angle: OLED displays have a wider viewing angle than TFT LCD displays. This means that the image on an OLED display remains clear and visible from a wider range of viewing angles.
Power Consumption: OLED displays consume less power than TFT LCD displays because they do not require a backlight. OLED displays only emit light in the areas where it is needed, resulting in better power efficiency.
Lifespan: OLED displays have a shorter lifespan than TFT LCD displays. This is because the organic materials used in OLED displays degrade over time and can result in image retention or burn-in.
In summary, TFT LCD and OLED are two different display technologies with their own unique characteristics. OLED displays have better contrast ratio, wider viewing angle, and lower power consumption, while TFT LCD displays have a longer lifespan. The choice between these two technologies ultimately depends on the specific requirements of the application and the preferences of the user.
