There are two main families of OLED

There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell which has a slightly different mode of operation. OLED displays can use either passive-matrix or active-matrix addressing schemes. Active-matrix OLEDs require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.Low Temperature OLED display Of -40- + 80 ℃ wide operating temperature,Under ultra-low temperature faster response time,Upper unlimited viewing angle of 175 degrees.16x2 oled screen with white Character of our company,active Area with 56.22(W)mm×11.52(H)mm,viewing Area with 58.22(W)mm×13.52(H)mm
