Final answer:
OLED (Organic Light Emitting Diodes) is the display technology that uses an organic semiconductor material to create light and images without the need for a backlight, offering superior contrast and color than other types like LCD and LED.
Step-by-step explanation:
The display technology that utilizes an organic substance as the semiconductor material is OLED (Organic Light Emitting Diodes). Unlike LCD (Liquid Crystal Displays) which use a large backlight to illuminate pixels, OLED screens feature individual pixels that produce their own light. This is possible due to the organic compounds that emit light in response to an electric current. OLED technology offers higher contrast ratios, deeper blacks, and a wider range of colors compared to LCDs.
Other display technologies such as LED (Light Emitting Diodes) are similar to LCDs but use LEDs for backlighting instead of the traditional CCFL (Cold Cathode Fluorescent Lamps). Plasma displays create images by illuminating tiny colored fluorescent lights. However, it is the OLED displays that stand out by using an organic material that acts as both a semiconductor and light source.
