Because the substrate handles heat dissolution exceptionally well, it is widely utilized for long, narrow LED edge-lit or direct-lit backlight arrays. It supplies stable voltages to the string of diodes illuminating the screen.
A few key recommendations:
: The specific board series or model designation often used in Innolux and Chimei panels. tpts mv-0s 94v-0 e88441 pdf
Finding a direct "PDF" for a specific PCB marking can be tricky because these codes describe the material , not necessarily the circuitry . However, you can find the technical specifications by following these steps:
standard guarantees that the materials used in the board will not contribute to a fire in the event of an electrical failure. Repair and Sustainability Finding a direct "PDF" for a specific PCB
The PCB is manufactured by , recognized under the UL file number E88441 , confirming it meets rigorous safety standards. 1. Decoding the TPTS MV-0S 94V-0 E88441 Marking
: This is the abbreviated tracking mark for the raw board fabricator, Taiwan Print Circuit Board Techvest Co., Ltd. . It indicates who pressed and layered the fiberglass board, rather than who populated it with chips. Chimei Innolux Panels
. It identifies the manufacturer of the raw PCB material, not the function of the board itself. : This is a standard UL 94 flammability rating
If you choose to replace the board completely rather than soldering individual micro-components, remember that matching the TPTS MV-0S 94V-0 E88441 designation is not enough. Because multiple display brands use this identical physical board footprint, you must also cross-reference the manufacturer part sticker (e.g., EACDJ6E10 for LG, or PT320AT-XC-1 for Innolux/DEXP) to guarantee compatible firmware.
