Drop Test
The packaged display shall be capable of passing drop test as specified in following specification without any measurable
degradation in performance or detectable mechanical or cosmetic damage.
Filter:
330 Hz
Dropping way: 1 corner, 3 edges, 6 flats
Dropping Height: follow the below table
Additionally, prior to production and prior to implementation of any design or manufacturing change that might affect
vibration performance, a minimum of 2 units shall be demonstrated to meet the requirements of specification.
VESA DDC
The VGA/HDMI inputs shall be capable of continuously transmitting its Extended Display Identification
( EDID ) information using Display Data Channel. It shall automatically switch to DDC2 mode if a DDC2
capable host is detected in accordance with the VESA DDC standard.
In addition, the display can respond to a request for EDID, to be transmitted using DDC2, level B commands.
If a DDC2 capable host is detected by the display, the display shall switch to DDC2 communication.
The EDID shall contain the manufacture name code QCI, product code, date of manufacture, and serial
number.
For complete EDID data structure, please refer to VESA Extended Display Identification Data Standard.
Hardware implementation may be either integrate into micro-controller or be a separate electrical
component. EDID memory must be protected against writing or other corruption through
customer-accessible electrical connection and required communication channels. Password protection, use
of an unpublished enable register, or use of direct electrical connection is acceptable levels of protection
provided that the power-on Default State is that disabling writing. The serial number fields in the EDID must
contain a unique identifying numbers among units of the same model. EDID Table is defined as below:
