Scope
This document is to define the standard test methods to evaluate the deformation of rollable display panel and module with multi-joint supporter, specifically surface deformation after rolling and surface deformation during push on rollable display panel and module. This document takes into account the surface waviness deformation under rolling stress and the deflection depth during push on the front surface of rollable display panel and module.
Purpose
In the display industry, the main display product line is moving from the existing glass substrate applied display to the plastic product applied flexible display. In addition, since the flexible display industry is expected to move from the current foldable display to the slider and rollable display products, it is necessary to secure evaluation criteria for the new deformation measurement of rollable display before launching a rollable display product.
