DBM068LCDM9K01 Datasheet – 6.8-Inch 8520×4320 9K Mono MIPI LCD

DBM068LCDM9K01 Datasheet provides the technical specifications for a
6.8-inch 9K monochrome LCD open cell featuring
8520 × 4320 mono resolution, 18 × 18 μm dot pitch,
LTPS TFT technology and a MIPI D-PHY 2-port, 8-lane interface.
The panel provides a 153.36 × 77.76 mm active area and is optically characterized using a
405nm UV backlight source.

DBM068LCDM9K01 6.8-Inch 9K Mono LCD Overview

The DBM068LCDM9K01 is a transmissive monochrome active-matrix LCD that uses
LTPS TFT switching devices. The open-cell assembly consists of the TFT LCD panel,
polarizers, driver IC and FPC.

Unlike a conventional RGB color TFT display, this model uses a monochrome dot matrix with an
8520 × 4320 resolution. Its very small 18 × 18 μm dot pitch
allows a high dot density within a 6.8-inch class active display area.

8520×4320 High-Resolution Monochrome Dot Matrix

The main characteristic of the DBM068LCDM9K01 is its
8520 × 4320 monochrome dot matrix.
The specified 18 × 18 μm dot pitch corresponds directly to the active display dimensions:

• 8520 × 18 μm = 153.36 mm horizontal active width
• 4320 × 18 μm = 77.76 mm vertical active height

Because this is a monochrome LCD, the resolution should be interpreted as individual mono dots rather
than conventional RGB color pixels. This distinction is important when comparing the panel with ordinary
consumer or industrial TFT displays.

LTPS TFT Open-Cell Construction

DBM068LCDM9K01 uses LTPS (Low-Temperature Polycrystalline Silicon) TFT
technology. The product is supplied as an FOG open-cell type rather than a complete
monitor module with conventional visible-light LED backlight and enclosure.

For integration projects, the optical system, controller electronics, mechanical support and UV light
source should therefore be designed as part of the complete system.

MIPI D-PHY 2-Port 8-Lane Interface

The module uses a specialized MIPI D-PHY interface with two ports and eight data lanes.
Each MIPI port contains four differential data lanes and one differential clock pair.

MIPI Port A

• A_D0P / A_D0N
• A_D1P / A_D1N
• A_D2P / A_D2N
• A_D3P / A_D3N
• A_CLKP / A_CLKN

MIPI Port B

• B_D0P / B_D0N
• B_D1P / B_D1N
• B_D2P / B_D2N
• B_D3P / B_D3N
• B_CLKP / B_CLKN

This interface architecture is significantly different from a conventional single-port MIPI display.
Controller-board compatibility should therefore be confirmed specifically for the DBM068LCDM9K01
rather than assuming that any standard MIPI controller can drive the panel.

51-Pin Interface Connector

The specification identifies XDYT 0-51162217-5 as the module electronics connector,
with compatibility references to STM FFSKL05011N51C and FCN FF01-42T-5131.

The 51-pin interface carries:

• MIPI Port A and Port B signals
• VDDIO digital power
• AVDD positive analog power
• AVEE negative analog power
• RESET signal
• TE tearing-effect signal
• FRM / BIST control
• Multiple ground connections

405nm UV Optical Performance

The optical characteristics of DBM068LCDM9K01 are specified using a
405nm UV backlight rather than a conventional visible-light luminance measurement.
This is an important distinction when evaluating this open-cell panel.

The published optical parameters are:

• Contrast ratio: 300:1 minimum
• Panel transmittance: 3.5% minimum, 4% typical
• Transmittance uniformity: 85% minimum

The specification states that contrast ratio, transmittance and transmittance uniformity are based on
the defined 405nm DUOBOND UV backlight measurement condition.

4% Typical UV Transmittance

The DBM068LCDM9K01 provides 4% typical panel transmittance under the specified
405nm UV optical condition, with a minimum value of 3.5%.

For UV optical system design, this parameter is more meaningful than conventional LCD brightness
expressed in cd/m². The actual optical performance of a finished system will also depend on the UV source,
optical distance, thermal design and other components in the complete optical path.

20Hz Frame Rate and Display Timing

The module is specified for a 20Hz typical frame rate. The timing table provides
a typical 263.3MHz PCLK frequency.

Published timing parameters include:

• PCLK: 263.3 MHz typical
• Vertical total: 4360
• Vertical active period: 4320
• Vertical blanking: 40
• Horizontal total: 3020
• Horizontal active period: 2840
• Horizontal blanking: 180

Because the General Specifications define the physical monochrome resolution as 8520 × 4320 dots while
the interface timing table lists a horizontal active period of 2840 clocks, controller developers should
follow the complete MIPI data architecture and confirm the required data mapping before finalizing hardware
or firmware.

LCD Power Supply Requirements

The panel requires three primary power rails:

Under the published full-white 20Hz condition, typical current values are approximately
43mA for VDDIO, 23mA for AVDD and -23mA for AVEE.

Operating Temperature and Reliability

The specified environmental range is:

• Operating temperature: 0°C to +70°C
• Storage temperature: -10°C to +80°C

Reliability testing includes:

• High-temperature storage: +80°C for 240 hours
• Low-temperature storage: -10°C for 240 hours
• High-temperature operation: +70°C for 240 hours
• Low-temperature operation: 0°C for 240 hours
• High-temperature/high-humidity operation: +60°C, 90% RH for 240 hours
