Display IP

Display IP

Qualitas Semiconductor provides various HSI IPs for display chipsets.​ Display chipsets have been gaining new momentum as it has been diversifying together with display panels. With the release of display devices supporting 8K UHD resolution following 4K UHD, the aim is to deliver sharper image quality and resolution. Representative display chipsets include DTV SoC, TCON IC, and DDI, and the development of high-speed interface IP for transmitting higher resolution and high-quality data is an important task for Qualitas Semiconductor.

Qualitas Semiconductor provides the major TCON interface standard eDP and intra-panel interface which transmits video signals from the TCON IC to the DDI running the panel.​

Intra-Panel eDP RX

eDP RX PHY

Request Datasheet

The eDP RX PHY IP is a cost- effective and low-power solution that includes IO pads and ESD structures. With extensive built-in self-test features, including loopback and scan support, it ensures robust functionality and easy verification. This hardmacro supports the eDP RX v1.4b and v1.5a standard and is commonly used for connecting a timing controller (TCON) to a host processor.

Features

  • Compliant with DisplayPort v1.4, eDP v1.4b, and eDP v1.5a
  • Supports for 1.62Gbps to Max 8.1Gbps data rate
  • Supports for eDP v1.4b feature such as PSR1 and PSR2
  • Supports for eDP v1.5a feature such as AUX-less Link Training
  • Adaptive continuous time linear equalizer (CTLE) and decision feedback equalization (DFE)
  • Automatic calibration of analog circuits and offset correction
  • Built-in eye open monitor
  • Built-in self-test (BIST) including pseudo random bit stream (PRBS) generation and checker

Intra-Panel TX PHY

Request Datasheet

Qualitas' Intra-panel TX PHY IP is an advanced chip-on-glass(ACOG) and chip-on-film(COF) transmitter embedded into the timing controller for TFT-LCD panel. The technology enables a single chip to support multiple display interfaces, reducing system cost and complexity. It also provides higher data transfer rates, low power consumption, and compatibility with a wide range of devices.

Features

  • Supports for 120Mbps to Max 4Gbps data rate
  • Supports Power Down Mode and Low-Power Mode during V-blank period
  • Programmable differential transmitter output impedance (75ohm ~ 180ohm)
  • Programmable different transmitter output amplitude (max 6dB)
  • Jitter Injector included for debugging feature
  • Built-in self-test (BIST) including pseudo random bit stram (PRBS) generation and checker
