Mirror display module

A mirror display module, comprising:

• a first substrate;
• a plurality of pixel units disposed on the first substrate;
• a second substrate disposed opposite to the first substrate;
• a display medium layer located between the first substrate and the second substrate;
• a reflection pattern disposed on the second substrate and located between the second substrate and the display medium layer, wherein the reflection pattern has a plurality of openings, and the openings are overlapped with at least a portion of the pixel units;
• a third substrate, wherein the second substrate is located between the third substrate and the first substrate;
• an electrochromic material layer located between the third substrate and the second substrate;
• a first transparent electrode disposed on the third substrate and located between the third substrate and the electrochromic material layer;
• and
• a second transparent electrode located between the electrochromic material layer and the second substrate, wherein the pixel units form a plurality of pixel groups, each of the pixel groups comprises a first pixel unit and a second pixel unit, one of the openings of the reflection pattern is overlapped with the first pixel unit, and a material portion of the reflection pattern shields the second pixel unit.
