Title:
QUANTUM DOT MODULATOR TUBE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/165660
Kind Code:
A1
Abstract:
A quantum dot modulator tube and a display device. The quantum dot modulator tube comprises a strip-shaped glass tube (12, 22 and 42) with two ends closed; an LED lamp bar (11, 21, 31 and 41) is disposed in the glass tube (12, 22 and 42); and electrodes (113 and 114) are led out from two ends of the LED lamp bar (11, 21, 31 and 41) and stretch out from the two ends of the glass tube (12, 22 and 42) respectively; the inner wall or the outer wall of the glass tube (12, 22 and 42) is coated with quantum dot fluorescent powder (13 and 43), the LED lamp bar (11, 21, 31 and 41) includes: a circuit substrate (111, 211, and 311), a plurality of LED chips (112, 212, 312 and 412) disposed on the substrate (111, 211 and 311) and a silicone layer (213, 313 and 413) for packaging the LED chips (112, 212, 312 and 412)on the circuit substrate (111, 211, and 311). Since the lamp bar (11, 21, 31 and 41) is disposed in the closed glass tube (12, 22 and 42), and the wall of the glass tube (12, 22 and 42) is coated with quantum dot fluorescent powder (13 and 43), the problems in the prior art that lots of quantum diaphragms material is used and the service environment of quantum bars is limited are solved.
