Product Specification of JD2704
[Q4K70 Microdisplay Die in Wafer Form]

1. INTRODUCTION

This is a general specification for Jasper Display Corp.’s JD2704 Microdisplay Die in Wafer Form Specification (4K2K resolution) for use in Liquid Crystal on Silicon (LCOS) microdisplay applications. Our high performance microdisplay die is a full digital backplane and is targeted for use in single and multi-channel optical systems for amplitude and phase modulation applications.
The Q4K70 microdisplay die has an array diagonal of 0.70” and offers a total resolution of 4160×2464; an additional 64 columns and 64 rows have been added beyond the 4K2K superset (4096×2400) to allow dynamic, convergence adjustment of the microdisplay component. Microdisplays manufactured using the JD2704 wafer are used with a companion driver board solution.

2. FEATURES

  • 4K2K (4096 x 2400) active 3.74 um pixels
  • Additional 64 columns and 64 rows for electronic alignment (for a total resolution of 4160×2464)
  • superset of DCI 4K “Scope” (4096 x 1716) and “Flat” (3996 x 2160)and Quad WUXGA resolutions ( 3840×2400)
  • 0.70” diagonal
  • Up to 180 Hz color field rate (Supports 60 Hz RGB frame rate, 180 Hz monochrome)
  • Up to 5V (adjustable) operation of Array for LC Performance
  • LVCMOS compatible I/O interface for Speed and Low Power
  • Controllable image border grayscale
  • Driver board solutions for single and multichannel system.
  • Amplitude and phase modulation applications
