Do you know about CH LCD？

In terms of imaging principle, CH LCD abandons the traditional screen's reliance on backlighting and instead uses a liquid crystal spiral structure to selectively reflect specific wavelengths of ambient light for image formation. The liquid crystal molecules can switch between planar and focal conic states, enabling transmittance and reflectance effects respectively, allowing images to remain stable without continuous power supply—demonstrating excellent bistable characteristics. Additionally, it eliminates the need for color filters and reproduces colors through optical interference, delivering rich color gradations and millions of colors, thereby overcoming the limitation of traditional e-paper's monotonous color reproduction.

Ultra-low power consumption is the core highlight of CH LCD. This screen only consumes a small amount of electricity during the switching of picture refresh, and can achieve zero power consumption during static picture display, significantly reducing the energy consumption of the device and effectively extending the battery life of smart terminals, which is in line with the current development concept of low-carbon and energy-saving industries. Compared with conventional LCD and MiniLED screens, its energy-saving advantage is particularly prominent, and it is the preferred screen for portable and long-standby electronic devices.

In terms of display performance, the CH LCD boasts excellent environmental adaptability. It has a nearly 180° ultra-wide viewing angle, with no color deviation or glare issues. It also follows the principle that "the stronger the light, the clearer the display", ensuring clear picture quality even in strong outdoor light conditions, completely solving the problem of unclear images on traditional screens under direct sunlight. Additionally, it supports an ultra-wide temperature range of -30°C to 85°C, with excellent resistance to temperature fluctuations and strong stability, making it suitable for various complex outdoor and industrial scenarios.

In addition, the CH LCD panel is thin, lightweight and flexible, capable of adapting to flexible cutting and large-scale splicing. Its production process is simple and the cost is controllable. It combines durability and practicality. With multiple technological advantages, it has already achieved mature application cases in multiple fields, covering commercial, transportation, medical, industrial, wearable and other scenarios.

In the field of smart retail, the CH LCD full-color electronic price tags are the core implementation product, occupying the mainstream market of cholesteric phase liquid crystal display applications worldwide. Different from traditional black-and-white electronic price tags, it can display high-definition product images, color prices, promotional information, has zero power consumption in static standby mode, and only consumes power during refreshing, adapting to the frequent update needs of supermarkets and warehouses with a large number of goods, significantly reducing the cost of manual price tag replacement and equipment energy consumption, and being the core component for the digital upgrade of new retail.

Intelligent transportation and outdoor public displays are its advantageous application scenarios. Many cities' intelligent bus stop signs, high-speed rail information screens, and road signs all adopt the CH LCD technology. Relying on the characteristics of strong light visibility and stable operation over a wide temperature range, they are not affected by outdoor complex environments such as sun exposure, high temperatures, and severe cold. The equipment does not require complex wiring and can operate for a long time with a micro battery. It can update real-time information such as train schedules, road conditions, and announcements, and can also be used for dynamic advertising display, balancing practicality and economy. Enterprises such as AUDE and HONGCAI PHOTONICS have launched large-sized CH LCD outdoor display screens, which have been widely implemented in urban public information display projects.

In medical and commercial scenarios, CH LCD displays are mainly used in hospital waiting area information screens, consultation room information boards, elevator intelligent light boxes, and building indication signs. With the features of no blue light, similar to paper eye protection, and ultra-low power consumption, they can stably display waiting information, health knowledge, and place guidance content for a long time, enhancing the intelligence level of public services, and at the same time meeting the commercial renovation requirements of low-carbon and environmental protection.

Furthermore, its flexible and customizable feature has also been extended to niche innovation fields, including flexible wearable displays, vehicle-mounted visual films, intelligent textile display fabrics, industrial outdoor instrument panels, Internet of Things intelligent labels, etc. It can fit irregularly shaped curved devices and adapt to extreme conditions. With stable performance, it continuously expands the application boundaries of new displays. In the future, the industrialization implementation scenarios will continue to be enriched.
