| UN R128: Proposal for Supplement [10] |
| Reference Number: GRE/2019/15 |
|
Proposal to insert a minimum luminance gradient as an alternative criteria. The current text requires a certain “asymmetry” of the Light Emitting Area (LEA) in order to ensure a “minimum worst-case gradient”; however, this requirement has been deemed too design-restrictive. |
