19″ High Brightness LCD Display with Controller Board for HMI

19" High Brightness LCD Display with Controller Board for HMI

A 19-inch SXGA TFT-LCD and VGA controller kit combining 1000 cd/m² typical luminance with a native 30-pin two-channel LVDS panel connection.

Product Summary

The 19" High Brightness LCD Display with Controller Board is designed for equipment that still relies on the 1280 × 1024 SXGA format but needs substantially more luminance than a conventional indoor display. Its 19-inch 5:4 layout is well suited to legacy HMI software, industrial dashboards, machine interfaces, retrofit equipment and other applications originally developed around square-format LCDs.

The LCD uses a TN, Normally White, transmissive structure with 1000 cd/m² typical luminance and a 1000:1 typical contrast ratio. Its native display connection is a 30-pin, two-channel, 8-bit LVDS interface. A separate RT2270C-A controller converts a VGA video input for the LCD.

VGA is a controller-side interface; the LCD panel itself remains an LVDS device.

Key Specifications

1280 × 1024 SXGA Format for Retrofit Interfaces

Native 5:4 workspace

The 1280 × 1024 native raster gives this display a 5:4 interface area that remains important in industrial and commercial systems built around earlier HMI software, control dashboards and fixed-resolution graphics.

Using the native 1280 × 1024 mode avoids unnecessary scaling and preserves the proportions of legacy menus, alarms, trend windows, maintenance screens and machine-status layouts. The 376.32 × 301.056 mm active area should be used when defining the visible window in a replacement enclosure.

A replacement screen should be qualified against native timing and image geometry, not only diagonal size.

TN viewing geometry

The panel provides an identified 85°/85°/80°/80° viewing specification for left, right, up and down at CR≥10. Because the panel uses TN technology, installed operator position should be considered when determining screen height and viewing orientation.

This is particularly important in equipment where the display is mounted significantly above or below the normal eye line.

1000 cd/m² Bright-Ambient Performance

The fixed 1000 cd/m² typical luminance gives the LCD considerably more optical headroom than many standard indoor panels. It can therefore be evaluated for factory environments, bright control rooms, protected kiosks and other equipment exposed to elevated ambient illumination.

However, finished readability depends on more than panel luminance. Front glass, reflections, air gaps, coatings, enclosure shading and installation orientation can materially alter the apparent contrast.

The 19" High Brightness LCD Display with Controller Board should therefore be evaluated behind the actual front window before direct-sun performance is specified.

A 1000 cd/m² rating does not by itself establish weatherproof or direct-sun performance for the finished equipment.

High Brightness LCD Display with Controller Board Integration

30-pin LVDS panel path

The LCD uses two-channel, 8-bit LVDS through a 30-pin connector. Connector count alone is not a compatibility standard.

Before another panel, cable or controller is substituted, engineering should verify native timing, LVDS channel mapping, bit mapping, connector orientation, pin assignment and all required electrical conditions.

A matching 30-pin LVDS connector does not guarantee electrical or timing compatibility.

VGA input through the RT2270C-A controller

The paired RT2270C-A board provides the external VGA interface. It performs the controller function between the VGA video source and the LCD's native LVDS connection.

This architecture is useful when a machine or legacy host already provides VGA and the objective is to replace or upgrade the screen without redesigning the complete host-video architecture.

The controller is specified for a 12 V DC supply above 2 A and can enter a no-signal standby state below 1 W. The standby figure should not be interpreted as maximum system consumption.

Keep panel and controller electrical requirements separate

A separate 35.0 V typical value appears in the LCD data, but its exact electrical role is not defined sufficiently for production release.

It should not be assigned to the LCD logic rail, controller supply or backlight circuit until the ordered electrical specification establishes what the value represents.

Mechanical Integration and Included Hardware

LCD and controller dimensions

The LCD outline is 396 × 324 × 11.7 mm, with a 376.32 × 301.056 mm active display area. These dimensions should be used separately when checking housing clearance and visible-window geometry.

The RT2270C-A controller board is identified at 107 × 38 × 18 mm. Board clearance must also account for VGA connector access, the LVDS harness, controller power connection, keypad cable and inverter/backlight wiring.

Kit components

The configuration includes the LCD screen, RT2270C-A VGA controller board, inverter board, LVDS cable and wired keypad.

This makes the package useful for prototype and retrofit evaluation because the main screen-to-controller connection hardware is already represented. The final enclosure and power system still need project-specific qualification.

Electrical and Revision Qualification

The ordered product should be locked to the correct G190ETN01-1000 and RT2270C-A revision before production. This is especially important because one descriptive line identifies 1024 × 768 while the principal product fields identify 1280 × 1024.

The final purchase specification should therefore confirm:

• native 1280 × 1024 timing;
• complete 30-pin LVDS definition;
• panel logic supply;
• exact function of the 35.0 V typical value;
• WLED/backlight and inverter electrical requirements;
• controller firmware and scaling behavior;
• cable orientation;
• required luminance tolerance.

Application Fit

This configuration is relevant to industrial HMI retrofits, production-machine interfaces, legacy SXGA control systems, kiosk equipment, protected information displays and embedded VGA-driven systems.

Its main commercial advantage is not simply high luminance. It combines a 19-inch 5:4 screen format with a controller path that accepts VGA, making it practical where existing software, mechanics and host hardware were built around older display standards.

The 19" High Brightness LCD Display with Controller Board should not be treated as an outdoor monitor or sealed industrial computer. Environmental protection, temperature range, vibration resistance, UV resistance and compliance requirements must be defined at system level.

Configuration and Customization

Controller-board matching, LVDS harness definition, cable orientation, enclosure adaptation, front-glass reflection control, optical treatment, backlight/inverter review, branding and packaging can be evaluated according to project requirements.

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

Procurement Checklist

Before sample approval or production release, confirm the assigned product revision, native 1280 × 1024 timing, 5:4 software layout, complete 30-pin two-channel 8-bit LVDS pin map, connector orientation, cable, panel logic voltage, and the electrical role of the separately listed 35.0 V typical value.

Also confirm WLED/backlight voltage and current requirements, inverter function, enable and dimming requirements, luminance tolerance, 1000:1 contrast, 85°/85°/80°/80° viewing specification, 376.32 × 301.056 mm active area, 396 × 324 × 11.7 mm LCD outline, RT2270C-A revision, 107 × 38 × 18 mm board dimensions, 12 V DC above 2 A controller supply, VGA behavior, included cables/keypad, environmental limits, sample criteria, quantity and annual demand.
