12.3 Inch Wide Vehicle HMI LCD Panel for Navigation Systems

12.3 Inch Wide Vehicle HMI LCD Panel for Navigation Systems

A panoramic 1920 × 720 IPS panel with 1200 cd/m² luminance and 40-pin LVDS for vehicle and equipment interfaces.

Product Summary

The Wide Vehicle HMI LCD Panel provides a long horizontal canvas for navigation, instrument, center-control and industrial interface layouts. Its 1920 × 720 native resolution supports route guidance, vehicle status, warning icons, operating data and segmented control graphics without requiring the height of a conventional widescreen panel.

The 12.3-inch module combines IPS viewing, 1200 cd/m² typical luminance, a 40-pin LVDS interface and a 292.03 × 109.51 mm active area. It is supplied as a non-touch display component and requires a compatible host, approved cable, defined panel and backlight power, and a mechanically validated enclosure.

Key Specifications

Panoramic 1920 × 720 Interface Layout

Navigation and Instrument Composition

The 8:3 format is suited to interfaces that distribute information horizontally. A vehicle layout can divide the screen into map guidance, route prompts, speed or machine data, warnings and status controls while maintaining a compact vertical profile.

Truck, agricultural-machine and industrial designs can use the same geometry for center-control navigation, operating states, process values or guidance information.

UI development should define:

• Driver or operator viewing distance
• Minimum text height
• Warning-zone priority
• Navigation-map allocation
• Icon and touch-free control sizes
• Day and night visual modes
• Screen mounting angle
• Physical-button or rotary-control workflow

Native Raster and Active Area

The display should be driven at its native 1920 × 720 resolution whenever practical. Non-native scaling can soften text, change gauge proportions and reduce the clarity of navigation graphics.

The active image region measures 292.03 × 109.51 mm. This value should be separated from the 310 × 128 mm front outline when defining the visible window, decorative mask and enclosure bezel.

1200 cd/m² Optical Performance

Finished-System Readability

The panel luminance is specified at 1200 cd/m² typical. This provides a strong starting point for vehicle cabins, machinery consoles and equipment exposed to substantial ambient light.

A 1200 cd/m² panel does not by itself establish finished-system sunlight readability after front glass, reflections, dimming and thermal conditions are applied.

The optical review should include:

• Front-glass transmission
• Decorative printing
• Air gap or optical bonding
• Surface reflectance
• Installation angle
• Direct and indirect sunlight
• Night-time dimming
• Backlight heating
• Enclosure temperature

Brightness should be validated at the completed front surface under representative lighting.

IPS Viewing and Contrast

The panel specifies IPS full-view performance with 88-degree viewing in the left, right, up and down directions. This supports vehicle and machinery interfaces where the screen may be viewed from offset seating or standing positions.

The 1000:1 typical contrast ratio supports clear separation between dark backgrounds, bright symbols and navigation graphics. It does not establish HDR performance or color-critical calibration.

40-Pin LVDS Integration

Host and Cable Qualification

The module uses a 40-pin LVDS connection.

A 40-pin LVDS connector does not guarantee timing, voltage, mapping or pin compatibility with another panel.

Before powering the panel, confirm:

• Native 1920 × 720 timing
• Pixel clock and blanking
• LVDS channel count
• Color-bit depth
• JEIDA or VESA mapping
• Connector manufacturer and pitch
• Contact side and pin-1 orientation
• Complete 40-pin assignment
• Panel-logic voltage
• Enable signals
• Ground and shielding design

The host schematic, cable drawing, panel pinout and controller documentation should be reviewed together.

Panel and Backlight Requirements

The product information confirms a WLED backlight but does not define the required panel voltage, backlight voltage, current, power, enable logic or dimming method.

Panel electronics and backlight power should be treated as separate design items until an approved electrical specification confirms their relationship.

The power review should cover:

• Panel-logic supply
• Input tolerance
• Startup sequence
• Backlight-driver output
• Enable polarity
• PWM or analog dimming
• Current limit
• Inrush behavior
• Thermal load
• Cable and connector rating

Mechanical Integration of the Wide Vehicle HMI LCD Panel

Outline and Rear-Structure Clearance

The product outline is 310 × 128 × 6.8 mm. The rear drawing shows a smaller rear-structure footprint, mounting features, cable routing and local thickness references that must also be considered.

Enclosure planning should define:

• Front opening
• Active-image margin
• Rear-cover clearance
• Cable exit
• Connector access
• Bend radius
• Mounting points
• Local keep-out zones
• Ventilation
• Service-removal path

The approved mechanical drawing should control bracket, bezel and housing release.

Non-Touch Front-Stack Planning

The standard configuration does not include touch.

The non-touch configuration requires a separate input method or independently qualified touch stack.

Projects may use:

• Physical buttons
• Rotary controllers
• Steering or console controls
• External keypad
• Independently developed touch panel
• Cover glass without touch

Adding a touch layer changes optical transmission, reflection, mechanical thickness, cable routing and electromagnetic behavior. It should be validated as a complete stack.

Temperature and Qualification Boundaries

The panel is specified for operation from −30°C to +80°C and storage from −30°C to +85°C.

These values support wide-temperature evaluation, but they do not independently prove:

• Automotive qualification
• Long-term operation at the maximum temperature
• Thermal-cycle durability
• Humidity resistance
• Vibration resistance
• EMC or ESD performance
• UV resistance
• Waterproofing
• Backlight lifetime
• Complete-system reliability

Qualification should use the final host, cable, backlight driver, enclosure, front glass and mounting structure.

Application and Configuration Review

The panel can be evaluated for:

• Vehicle navigation displays
• Instrument and status panels
• Truck center-control interfaces
• Agricultural-machine guidance systems
• Off-highway equipment displays
• Industrial HMI panels
• Wide-format equipment information displays
• Non-touch control and monitoring terminals

The module is a component panel, not a finished navigation system. GPS, vehicle communications, HDMI conversion, audio, media playback, operating software and complete power conversion require additional hardware.

Configuration Scope

Project review may cover:

• LVDS controller and cable matching
• 40-pin assignment
• Front cover glass
• Anti-glare or anti-reflective treatment
• Optical bonding
• Enclosure adaptation
• Mounting brackets
• Backlight drive and dimming
• Optional touch development
• Branding and labeling
• Qualification documentation

Custom configurations are generally reviewed from 500 pieces, subject to tooling requirements, material availability and the requested specification. Sample and standard-module quantities are confirmed separately.
