Document Type and Number:
WIPO Patent Application WO/2023/226611
Kind Code:
A1
Abstract:
A lamp panel (100) and a preparation method therefor, and a backlight module. The lamp panel (100) is provided with a light-emitting side and a backlight side. The lamp panel (100) comprises a light-emitting device (20), wherein the light-emitting device (20) is provided with a positive electrode connecting portion (21) and a negative electrode connecting portion (22); and a reflector (10), wherein the side of the reflector (10) located on the light-emitting side is provided with a plurality of electrical connecting portions (110), each electrical connecting portion (110) comprises a positive electrode pad (111) and a negative electrode pad (112), the positive electrode connecting portion (21) is electrically connected to the positive electrode pad (111), the negative electrode connecting portion (22) is electrically connected to the negative electrode pad (112), the reflector (10) is provided with a via hole (11) penetrating two sides of the reflector (10), the side of the reflector (10) located on the backlight side is provided with a connecting circuit (120), and the positive electrode pad (111) and the negative electrode pad (112) are electrically connected to the connecting circuit (120) by means of the via hole (11). When the light-emitting device (20) is fixed, silver gel is not covered by a reflector plate or ink, so that the phenomenon of cracking of the reflector plate or the ink caused by curing of the silver gel can be avoided.
