Introduction
Attached to the Generic Display Connector found on various Toradex products (such as the Colibri Evaluation Board and the Orchid) the Toradex LCD-Converters family of products enables the attachment of Industry Standard Panels with a LVDS Interface. Currently there are two member of this product line available:
- LVDS_A1715_V01_00a: LVDS Converter 1.25mm pitch
- LVDS_A1715_V01_00b: LVDS Converter 1.0mm pitch
Each of these Converters consists of an assembled PCB implementing the LVDS conversion as well as a corresponding LVDS cable used to interface to the LCD.
Reference Document
For detailed technical information about the LVDS Converters please refer to the documents listed below:
- The various configuration of the digital RGB interface provided by the Colibri modules are described in detail in the datasheets of the corresponding processors.
Note: Marvell requires a Non Disclosure Agreement to be signed before customers get
access to their documentation.
- The VESA SPWG 2.0 Specification (Standard Panel Working Group) defines standard mechanical and electrical characteristics for Industry Standard Panels: http://www.vesa.org/Public/Panel%20Standards/StdPanel2.0.pdf
- The definition of the electrical interface is described in: TIA/EIA-644 Electrical Characteristics Of Low Voltage Differential Signaling (LVDS) Interface
Functional Description
The 18 bit RGB signals from the graphic controller are input to the LVDS Converter module. There the parallel RGB data is multiplexed and converted to a single channel LVDS (Low Voltage Differential Signaling) interface in order to be connected to the LCD. On the Display itself the received data is then demultiplexed, converted back to TTL levels and sent to the inputs of the timing controller. The use of the LVDS interface allows the data to travel at faster speeds across a narrow interface, addressing needs associated with high bandwidth communication.
