12.3 inch IPS 1920x720 LCD Display Bay Type TFT Module with Touch Screen

DESCRIPTION

The 12.3-inch IPS 1920x720 LCD Display Bay Type TFT Module (Model No: C123HAX02.2) integrates a wide-viewing IPS panel with high-resolution performance and capacitive touch capability. With a diagonal measurement of 12.3 inches, the display offers a resolution of 1920 (RGB) × 720 pixels, ensuring sharp and clear visuals. Designed in a normally black mode with IPS viewing direction, it guarantees excellent contrast and stable color reproduction across angles. The module features a robust structure with an outline dimension of 325.86 × 139.21 × 8.2 mm and a 70-pin LVDS interface for stable transmission. Complementing the display, the touch panel adopts a capacitive sensor with advanced AG/AR/AF coverlens treatments, enabling precise finger detection and glove touch support.

Core Display Characteristics

Display Technology and Optical Features

The display adopts an IPS (In-Plane Switching) structure, which ensures consistent brightness and color fidelity even at wide viewing angles. Its normally black mode enhances contrast by maintaining deep black backgrounds, essential for modern infotainment, industrial interfaces, and advanced instrumentation.

The active area of 292.032 × 109.512 mm with a fine dot pitch of 152.1 μm enables accurate pixel definition, while the RGB stripe arrangement ensures vivid color rendering. Surface treatments, including hard coating (HC) on the polarizer and anti-glare/anti-reflection/anti-fingerprint (AG/AR/AF) on the cover glass, contribute to improved durability and visibility under diverse environments.

Electrical and Mechanical Integration

The module operates with a 70-pin LVDS interface, facilitating efficient data transmission. With a maximum power consumption of 16.3 W, it achieves a balance between performance and energy efficiency. It is engineered for robust applications, maintaining functionality across a broad operating temperature range of -20°C to +70°C and storage range of -30°C to +80°C.

Touch Panel Technology

Sensor Structure and Accuracy

The 12.3-inch capacitive touch panel aligns perfectly with the active display area, offering a responsive and stable user interface. It is constructed with 48 × 20 channels, with a sensor pitch of 6.08 × 5.48 mm, ensuring fine detection accuracy.

• Accuracy error excluding edges: ≤ 0.8 mm

• Linearity error (excluding edges): ~0.8 mm

• Full-panel accuracy: ≤ 2.0 mm

The system responds with a reaction time ≤ 29 ms and refresh time of 18 ms, enabling smooth interactions suitable for navigation, industrial controls, and advanced HMIs.

Enhanced Usability

The touch solution supports glove operation up to 4.4 mm thickness and finger detection within 5–35 mm range, expanding its usability in automotive and industrial fields. With anti-glare/anti-reflection/anti-fingerprint treatments, visibility remains uncompromised even under sunlight or frequent handling.
