Problems solved by technology
[0003] Taking flexible LED displays as an example, although some new technologies in similar technical fields such as OLED (Organic Light-Emitting Diode) have realized the characteristics of partial flexibility and variability of the screen, compared with flexible thin-film LED displays , is a different technical solution, which cannot solve the technical problems of large-scale and long-life display screens
[0004] In the field of LED display, it is required that the LED display screen should be easy to transport, light and thin, easy to disassemble and changeable shape. Due to the limitation of the structural size of the integrated outer frame, power system, control system, packaged LED wafer, packaged driver chip, etc., the technical effect is not obvious, and it also causes the display screen to have a grainy feel, which affects the display effect.

The invention discloses a stickup ultrathin full color LED film display screen, and belongs to the LED display field; the stickup ultrathin full color LED film display screen comprises a film display screen body, a plurality of LED wafer groups, a plurality of drive IC bare chips, and a FPC flexible interface circuit boards; each LED wafer group comprises three LED wafers including a red LED wafer, a green LED wafer and a blue LED wafer; the features are that the film display screen body comprises a lighting layer, a first bonding layer, a second bonding layer, a third bonding layer, a lighting layer front protection layer, a lighting layer back protection layer, and a glue protection layer; the advantages are that RGB wafers with no package and drive ICs can be upside-down mounted on a conductive film substrate capable of changing, bending or even being folded, thus realizing upsizing and industrialization of the ultrathin full color LED film display screen, saving cost and materials, and improving production efficiency in transportation, installation and on production lines.
Description
technical field [0001] The invention relates to the field of LED display, in particular to an ultra-thin full-color LED film display screen that can be pasted. Background technique [0002] LED display screens are widely used in all aspects of production and life in modern society because of their advantages of energy saving, environmental protection, firm structure, and long service life. It is a large display terminal used outdoors all-weather; while it is used indoors, its series of products such as: small-pitch high-definition screen, advertising and teaching all-in-one machine, military and civilian dual-use security monitoring equipment and flexible LED display are leading technological innovation and emerging market development. [0003] Taking flexible LED displays as an example, although some new technologies in similar technical fields such as OLED (Organic Light-Emitting Diode) have realized the characteristics of partial flexibility and variability of the screen...
