OLED display is expected to enter the era of large size

Compared with widely used TFT-LCD and PDP display technologies, OLED (Organic Light Emitting Diode) displays self-illumination, fast response, high brightness, high contrast, ultra-light and ultra-thin, low power consumption, no viewing angle limitation, and operating temperature range Wide, shock-resistant performance, soft display and many other advantages. However, due to the failure of the product yield and process technology bottleneck, OLED has not been able to enter the practical stage in large-size notebook and TV display applications.

Recently, German equipment manufacturer Mbraun has received orders from TV manufacturers for the production of 42-inch OLED TV panels, indicating that OLED TVs will soon be available, and OLED displays are about to enter the era of large size.

The positive active material is mainly made of nickel, and the negative active material is mainly an alkaline battery made of cadmium.The nickel-cadmium battery used in AGV car has large internal resistance and can be used for large current discharge.Compared with other kinds of batteries, nickel-cadmium batteries can withstand overcharge or overcharge, and the operation is simple and convenient.The discharge voltage is somewhat different according to the discharge current. In general, the discharge termination voltage of about 1.2v nickel-cadmium battery is 1.0v /CELL, and the actual operating temperature ranges from -20 degrees to 60 degrees. In this range, the discharge can be repeated for more than 500 times.
