Many thermometers have liquid crystal displays (LCDs), but LCDs without backlighting do not emit light, making it difficult to read the numbers at night or in dark places.
OLED (Organic Light Emitting Diode) is a self-luminous display, which makes it possible to read letters and numbers clearly even in the dark.

The thickness and weight of OLED is less than half of LCD, making it an excellent thin and light display.
It can contribute to the miniaturization and weight reduction of thermometers, which are often used by children.

We manufacture and sell standard OLEDs with a minimum size of 0.5 inches and a maximum size of 3.6 inches.
Since standard OLEDs do not require development costs, we are able to reduce introduction costs and provide samples and demo units in a short period of time.
If there is no standard OLED available in the size and specifications you need, we also offer semi-custom and custom development services.
