Technology
Seven layers. Eighteen stations. One specification.
The distance between an assembler and a manufacturer is measured in how much of the process is owned. This is the whole of it, published.
Construction
The stack, top down.
Four of the seven layers are specified by supplier and not merely by tolerance. That is the part a competitor cannot match on price alone, because it is a purchasing decision made before the line starts.

BOE · Tianma · JDI · AUO
The same four panel makers that supply the handset industry. RISGOO describes the relationship as in-depth cooperation and strategic partnership, which is a supply position rather than an endorsement.
The line
Eighteen stations, glass loading to FPC bend.
Fully automatic ACF attachment, fully automatic COF/COG bonding, automated optical inspection for particle detection at the bond, and a three-in-one dispensing head for silver, face glue and wire glue. The stations in orange are the ones the factory marks as determining yield.

In-line control
Five checks that run continuously, not on a sample.
Distinct from the destructive rigs. These are the measurements the line takes on itself while it is running.

What it holds
The four numbers the whole construction exists to produce.
500nit
Brightness
Held across the sheet, not peaked at centre. Uniformity is a backlight-assembly problem before it is a panel one.
120Hz
Refresh rate
Driver and bonding qualified to the same rate as the handsets these replace.
99.99%
NTSC coverage
Colour calibrated per programme rather than per batch, which is what makes unit-to-unit drift measurable.
35%
Heat dissipation
Improvement from a graphene layer, against RISGOO's own previous construction.
Upstream
Ten thousand square metres, and the panel supply behind it.
The 2024 line at Hongrongyuan Honghu Science and Technology Park is the second production investment, not the first.
