Comprehensive Analysis of LCD Black Technology (Part 3): 7 Major Featured Technologies, Reshaping the Ultimate Experience

In the previous two articles, we explained the structure, connection, types, and display modes of LCDs. As a custom LCD display manufacturer and an experienced LCD display factory, CNK is a specialized and sophisticated high-tech enterprise dedicated to the R&D, production, and sales of display devices and HMI human-machine interaction products. Its core products include monochrome LCDs and monochrome modules, 0.96-15.6 inch TFT display modules, OLED modules, and HMI human-machine interaction modules. Today, we will focus on the 7 most breakthrough featured technologies. These technologies have been comprehensively upgraded in terms of visual effects, function expansion, and environmental adaptability, allowing LCDs to break out of the limitation of "simple display" and demonstrating the strong strength of China TFT displays.

I. Colorful Display

1. Supports dual schemes of "VA + Silk Screen" and "VA + Multi-Color Backlight", enabling customization of color zones and patterns with rich color presentation, meeting the visual personalization needs of consumer electronics and smart devices.

2. Covers FS LCD positive display and FS + VA LCD negative display modes, adapting to the visual needs of different scenarios. When paired with CNK's OLED modules, the color performance is more outstanding.

II. CTP Key Function

1. Provides built-in/external single and multi-touch schemes, realizing the integrated design of "display + touch", which is deeply compatible with CNK's HMI human-machine interaction modules.

2. Features sensitive touch response and clear key feedback, simplifying the device structure, improving the sense of technology and operational convenience, and is the preferred scheme for smart control panels and automotive touch screens.

III. Special Structure

1. Breaks through size limits: COG supports a maximum of 7.5 inches (L165 * W100mm), and COB extends to 11.8 inches (L290 * W80mm), covering the full size range of 0.96-15.6 inches, meeting large-size display needs and demonstrating the production strength of a display manufacturing company.

2. Supports COG ITO bridging, dual LCD cell display, and arbitrary polygon customization, adapting to special installation scenarios, fully reflecting the flexible customization capability of a custom LCD display manufacturer.

IV. High Contrast

1. DFSTN has a contrast ratio of ≥40:1, remaining clearly readable under strong light; the PMVA type has better contrast performance, with excellent performance under different duty modes.

2. The high distinguishability ensures that dark details are not lost and bright areas are not overexposed. When paired with CNK's TFT display modules, the image quality is more transparent and delicate.

V. Wide Viewing Angle Display

1. The static VA wide viewing angle has a vertical and horizontal viewing angle of ±60° under the premise of a contrast ratio of ≥20:1, ensuring no deviation in image quality when viewed from multiple angles and solving the pain point of limited viewing angles of traditional LCDs.

2. Covers 1/8 duty VA and 1/1 duty TN positive display wide viewing angle modes, eliminating viewing angle blind spots, and is suitable for multi-person viewing scenarios such as automotive displays and public display screens.

VI. Ultra-Wide Temperature Adaptation

1. Equipped with ITO GLASS heating sheets, the operating temperature range is -40~80℃, and the test temperature range is extended to -45~90℃, ensuring stable operation in extreme environments.

2. Both COG and COB structures support ultra-wide temperature design, adapting to harsh scenarios such as industrial control and outdoor equipment, reflecting the high-quality craftsmanship of the LCD display factory.

VII. Low Power Consumption Design

1. Optimizes IC and LC schemes, with power consumption as low as half of conventional products. The minimum power consumption of 132*65 dots is 50uA, achieving significant energy-saving effects.

2. The minimum power consumption of 240*65 dots is 100uA, balancing image quality and energy saving, adapting to portable products such as smart wearables and IoT devices, and perfectly matching CNK's low-power modules.

From basic architecture to core performance, and then to innovative featured technologies, CNK, as a professional display manufacturing company and a reliable China TFT display supplier, has always taken technological innovation as the core, providing high-quality display solutions for diverse scenarios such as consumer electronics, industrial control, and automotive equipment. In the future, CNK will continue to deepen its presence in the display field, unlock more black technologies, and create greater value for customers!
