Embodiment 1

[0027] Such as figure 1 As shown, a flexible electronic paper electronic display device includes a flexible base layer 1, the bottom of the flexible base layer 1 is bonded with an LED chip 2, the bottom of the LED chip 2 is provided with a circuit layer 3, and the circuit layer 3 includes a conductive layer 4 and an insulating layer 5 , the top of the conductive layer 4 is provided with an insulating layer 5, the top surface of the insulating layer 5 is provided with an ink layer 6, the top surface of the ink layer 6 is electrically connected to the LED chip 2, and the flexible base layer 1 is a PDLC substrate. In the design of the flexible display , Injection considers avoiding short circuit of crossing lines. In order to make the flexible display screen as transparent as possible when passing through, the amount of printed lines should be made small under the inlay to ensure the conduction of the lines. In order to avoid crossing lines, an ink layer 6 is used. , the insulati...

Embodiment 2

[0029] Such as figure 1 and figure 2 As shown, a method for manufacturing a flexible electronic paper electronic display device includes the following steps:

[0030] Sp1: The circuit layer 3 is welded into the conductive layer 4 with a circuit with a diameter of 50±5μm, and baked in a drying oven at 100° for 20 minutes;

[0031] Sp2: The circuit layer 3 is provided with insulating bumps on the top surface of the connection node of the conductive layer 4 to form an insulating layer 5, and put it in a drying oven at 110° for 30 minutes;

[0032] Sp3: heat the conductive ink into a slurry by heating it in a high-temperature heating box;

[0033] Sp4: The surface of the insulating layer 5 is printed and sprayed with conductive ink to form the ink conductive layer 4, put it in a drying oven and bake at 110° for 30 minutes;

[0034] Sp5: Paste the LED chip 2 on the surface of the PDLC substrate by using the crystal-bonding process, place it in a drying oven at 120° for 40 minut...

Abstract

The invention provides flexible electronic paper electronic display equipment and a manufacturing method thereof, and relates to the technical field of road and bridge technologies. The flexible electronic paper electronic display equipment comprises a flexible base layer, an LED chip is adhered to the bottom of the flexible base layer, a circuit layer is arranged at the bottom of the LED chip, the circuit layer comprises a conductive layer and an insulating layer, the insulating layer is arranged at the top of the conductive layer, and an ink layer is arranged on the top surface of the insulating layer. The top face of the ink layer is electrically connected with the LED chip, the flexible base layer is a PDLC base material, the PDLC base material is adopted as a flexible base material of electronic paper, the flexible electronic paper is prepared through three-layer overprinting through ink-jet printing, and the flexible display device which is passively displayed and can be bent is achieved. Compared with a traditional glass or metal display substrate, the PDLC used as the base material can be bent in any direction to a certain extent, the weight of the electronic paper is reduced, the bending degree is larger, resources are saved, use is convenient, conductive spraying is conducted on the surface of the electronic paper through the ink jet technology, forming is simpler, cost is low, the forming efficiency and speed are both improved, and the use performance of the electronic paper is improved.

Description

technical field [0001] The invention relates to the technical field of road and bridge technology, in particular to a flexible electronic paper electronic display device and a manufacturing method thereof. Background technique [0002] As a new type of display technology, flexible e-paper display technology has become one of the important directions of modern display technology research due to its small size, light weight, low power consumption, and passive luminescence. The rapid growth of the e-paper display market stems from some of its Excellent performance. Compared with cathode ray tube displays, liquid crystal displays and thin-film electroluminescent flat panel displays, electronic paper displays have the following advantages: energy saving and environmental protection, no background light source, passive image maintenance, and power consumption only when the screen changes. Compared with LCD, the power is reduced by more than 90%; the electronic paper display realiz...
