SIST EN 61747-2-2:2005 is a Slovenian national standard published by Slovenski inštitut za standardizacijo that adopts EN 61747-2-2:2004, based on IEC 61747-2-2:2004. It is a blank detail specification for matrix colour LCD modules, so it tells a user how to write a device-specific specification for assessed quality, ratings, tests, marking and ordering information. In practice, it is used by spec writers, manufacturers, test labs and buyers who need one agreed document for a particular LCD module type.
What does SIST EN 61747-2-2:2005 specify?
SIST EN 61747-2-2:2005 specifies the format and required content for a detail specification for matrix colour LCD modules. It is meant to be completed with device-specific values and options, so the document itself does not define one fixed product design, but the information that a product-specific document must contain.
The standard is organized into clauses 1 to 10. These cover mechanical description, short description, assessed quality category, marking, ordering information, limiting values, operating range and electrical and optical characteristics, test conditions and inspection requirements, qualification approval test, and additional information.
What are the key requirements of SIST EN 61747-2-2:2005?
SIST EN 61747-2-2:2005 requires the detail specification to identify the module type and the main design features in Clause 1 and Clause 2. That includes matrix addressing type, electro-optical effect, optical mode such as transmissive, reflective or transflective, number of colours, number of grey levels, preferred viewing direction, interface, integrated light source and intended application. For a buyer or engineer, this is the part that says exactly what kind of LCD module is being specified.
Clause 3 links the device to the category of assessed quality. The detail specification also has to include the information needed for reference data and the outline reference, such as dimensions, display format, pixel or dot pitch, colour pixel arrangement, and connection type. This matters because it fixes the physical and functional identity of the module before any testing starts.
Clause 4 covers marking, and Clause 5 gives the minimum ordering information. An order needs the precise type reference, the IECQ reference of the detail specification, the assessed quality category, and any other agreed particulars. That helps avoid ambiguity when ordering a specific LCD module or comparing offers.
Clause 6 sets up the limiting values using the absolute maximum rating system. It covers operating ambient temperature, storage temperature, supply voltages, input signal voltage, integrated light source voltage where relevant, and soldering temperature where relevant. The detail specification inserts the actual values, so the user knows the safe limits that must not be exceeded.
Clause 7 gives the recommended operating range and the electrical and optical characteristics. It covers supply voltage range, input signal high and low levels, analogue video signals where appropriate, operating frequency range, supply current, light source current, contrast ratio, display luminance, luminance uniformity, viewing angle range, rise time, fall time, transmittance, reflectance, and chromaticity of white, red, blue and green. In practice, this is the performance section that sets what the module must deliver and how it will be judged.
Clause 8 sets the test conditions and inspection requirements. It separates lot-by-lot inspection, periodic tests and destructive tests, and it says tests are made at 25 °C unless otherwise specified. The inspection groups include visual examination, dimensions, contrast ratio, luminance, chromaticity, viewing angle, response times, transmittance, reflectance, bond strength, environmental tests, electrical endurance, and permanence of marking. That gives manufacturers and laboratories the acceptance plan to use in quality control.
What terms does SIST EN 61747-2-2:2005 define?
- Blank detail specification - A template for a product-specific standard that must be completed with the actual device data.
- Category of assessed quality - The quality level used in the IECQ system to classify the module for assessment and supply.
- Screened sequence - An inspection sequence that may be required when ordering, as referenced from the sectional specification.
- Integrated light source - The light source built into the module, such as a backlight, front-light or LED arrangement.
- Preferred viewing direction - The viewing direction that the detail specification selects for optical measurements and performance values.
- Transmissive, reflective, transflective - The optical modes listed for the module, describing how the display uses light.
- IECQ - The IEC Quality Assessment System for Electronic Components, under which the detail specification is used.
Who uses SIST EN 61747-2-2:2005?
SIST EN 61747-2-2:2005 is used by LCD module manufacturers, qualification labs, quality managers, and buyers who need a controlled product specification. It is also used by organizations writing purchase specifications or approval documents for flat panel display devices. The standard is most relevant when a team needs to define the module’s electrical, optical, mechanical and inspection requirements in one agreed format.
Which standards are used with SIST EN 61747-2-2:2005?
SIST EN 61747-2-2:2005 is used together with EN 61747-1:1999, EN 61747-2:1999 and EN 61747-5:1998. The document also names the IEC counterparts IEC 61747-1:1998, IEC 61747-2:1998 and IEC 61747-5:1998. Together, these companion standards provide the generic specification, the sectional specification, and the environmental, endurance and mechanical test methods that the blank detail specification relies on.
What does the SIST EN 61747-2-2:2005 document contain?
SIST EN 61747-2-2:2005 contains filled-in tables for the values that a detail specification must state, including limits, operating ranges and performance characteristics. It also contains inspection tables for group A, B and C testing, with references to the related test methods in the companion standards. Figure 1 explains the supply voltage arrangement, and Clause 10 lists optional additional information such as pixel charts, timing charts, interface timing ratings, luminance measuring points, ESD precautions, installation precautions, handling information, safety and recycling information, and characterization of diffused and specular reflectance and transmittance.
