OLED has been widely used in mobile devices and the television industry, as it is favored by many people for being lighter and thinner. OLED also has good applications in the transparent screen industry. Let's take a look at the advantages of OLED transparent screens.

1、 The principle and characteristics of OLED transparent screens

1. OLED transparent screen display technology can be divided into two categories based on the driving mode: passive (passive matrix, i.e. PM-OLED) and active (active matrix, i.e. AM-OLED).

2. Passive mode is suitable for small-sized panels because its instantaneous brightness is proportional to the number of cathode scanning columns, so it needs to be operated under high pulse current, which will shorten the lifespan of pixels. And due to the scanning effect, its resolution is also limited, but its low cost and simple process are its major advantages.

3. Active mode has the opposite characteristics to passive mode. Although it is expensive and has a more complex manufacturing process (still easier than TFT-LCD), each pixel can be continuously and independently driven, and the driving signal can be memorized. It does not need to operate under high pulse currents, has high efficiency, and can also extend its lifespan. It is suitable for full-color OLED display products with large size, high resolution, and high information capacity.

2、 The advantages of OLED transparent screens

Compared to the crystal layer of LED or LCD, the organic plastic layer of OLED is thinner, lighter, and more flexible. The luminescent layer of OLED is relatively light, so its substrate can use flexible materials instead of rigid materials. OLED substrate is made of plastic material, while LED and LCD use glass substrate. LED and LCD require glass as a support, and glass will absorb some of the light. OLED does not require the use of glass.

3、 The advantages of OLED screens

The thickness can be less than 1 millimeter, only 1/3 of the LCD screen, and the weight is also lighter; Solid state mechanism, without liquid substances, therefore has better seismic performance and is not afraid of falling; There is almost no issue with visual angle, and even when viewed from a large angle, the image remains undistorted; The response time is one thousandth of that of an LCD, and there will definitely be no dragging effect on the displayed motion picture; Good low-temperature characteristics, can still display normally at minus 40 degrees Celsius, while LCD cannot achieve it; Simple manufacturing process and lower cost; Higher luminous efficiency and lower energy consumption compared to LCD; Can be manufactured on substrates of different materials, and can be made into flexible displays that can be bent.

Overall, the advantages of OLED transparent screens are very obvious, but they cannot completely replace all screens, after all, their shortcomings cannot be ignored, and this is also the direction that needs improvement in the future.
