From control panels of industrial automation to monitoring interfaces of medical equipment, from central control screens of smart homes to in-vehicle terminals of transportation, TFT LCD displays serve as the "visual core", whose performance directly affects product usability and competitiveness. However, facing the wide variety of TFT LCD products on the market, how to select based on parameters such as "resolution, brightness, interface, and working environment" has become a challenge for many engineers. As a professional TFT LCD manufacturer established in 2007, Reshine Display relies on 16 years of industry experience, a team of 10 R&D engineers, 10 precision production lines, and a monthly capacity of 750,000 units to build a TFT LCD product matrix covering 2.4 inches to 32 inches. Meanwhile, we provide customized services with high brightness, wide viewing angles, and multiple interfaces, ensuring quality with ISO 9001:2015 and SGS certifications, and offering "precision-matched" TFT LCD solutions for industries including industrial, medical, and consumer electronics.
Selecting a TFT LCD display essentially involves matching key parameters with "application scenarios". Among these, resolution, brightness, interface, operating temperature/humidity, and viewing angle are the five core dimensions – any mismatched parameter may lead to poor product experience or malfunction.
Resolution determines the image sharpness of TFT LCD displays, with common resolutions including 800×480 (WVGA), 1280×720 (HD), and 1920×1080 (FHD). For example, control panels of industrial equipment mainly display data and icons, so 800×480 resolution is sufficient; medical monitors need to display detailed information such as waveforms and text, so 1280×720 or higher resolution is required to ensure data accuracy; scenarios such as kiosks and in-vehicle terminals that need to display images or videos benefit from 1920×1080 (Full HD) resolution for better visual experience . Reshine Display’s TFT LCD products cover mainstream resolutions from 800×480 to 1920×1080, with some customized products supporting 2560×1440 (QHD) to meet high-definition needs.
Brightness, measured in "nits", is crucial for clear display of TFT LCDs under strong light. For ordinary indoor scenarios (such as smart home central controls and office equipment), 250-500 nits is sufficient; outdoor scenarios (such as outdoor kiosks and in-vehicle displays) require brightness of 800 nits or higher, otherwise, the screen may be "unseen" under direct sunlight; industrial scenarios (such as metallurgical and welding workshops) with complex lighting may even need ultra-high brightness of 1500-2000 nits . Reshine’s 21.5-inch TFT LCD display (Model: RXL215090-C) is a representative high-brightness product, with a brightness of 900 nits, resolution of 1920×1080, and LVDS interface, suitable for outdoor kiosks and industrial high-brightness scenarios . Meanwhile, Reshine supports customized brightness ranging from 250 nits to 2000 nits, adjustable according to customers’ specific usage environments.
The interface of TFT LCDs determines the convenience of connection with main control equipment (such as microcontrollers, embedded motherboards, and Raspberry Pi). Common interfaces include LVDS, MIPI, RGB, SPI, eDP, and HDMI . Industrial equipment mostly uses LVDS interfaces (with long transmission distance and strong anti-interference capability) – Reshine’s 21.5-inch TFT LCD adopts an LVDS interface, compatible with industrial motherboards; consumer electronics and embedded projects (such as Raspberry Pi and Arduino) commonly use HDMI or SPI interfaces – Reshine can customize interface types. For example, we customized a 7-inch TFT LCD with an HDMI interface for a smart home customer, directly adapting to the central control motherboard without additional adapter boards; medical equipment has high stability requirements – Reshine provides MIPI interface options with fast transmission speed and low power consumption, suitable for battery-powered portable medical equipment.
Usage environments vary greatly across industries – industrial automation, in-vehicle, and outdoor equipment need to withstand high and low temperatures, while medical equipment needs to adapt to the humidity of disinfection environments. Reshine’s TFT LCD products have a default operating temperature of -20℃~70℃ and storage temperature of -30℃~80℃, meeting most scenarios; for extreme environments (such as outdoor winter in northern regions and high-temperature workshops), Reshine can customize wide-temperature versions, extending the operating temperature to -40℃~85℃. Meanwhile, moisture-proof treatment ensures stable operation in environments with 90% humidity (no condensation), adapting to scenarios such as cold chain monitoring and outdoor weather stations.
Viewing angles are divided into TN (Twisted Nematic) and IPS (In-Plane Switching). TN screens have narrow viewing angles (clear only from the front), suitable for single-user operation devices (such as POS machines); IPS screens have wide viewing angles (178° visible from all directions), suitable for multi-person viewing scenarios (such as medical consultation screens and industrial collaboration panels) . Reshine provides IPS viewing angle options by default to ensure no color deviation when viewed from different angles. For example, we customized a 15-inch medical consultation TFT LCD with an IPS viewing angle, allowing doctors to clearly see patient data from different positions; meanwhile, Reshine also offers TN screen options to meet the needs of cost-sensitive customers.
Reshine Display’s TFT LCD products are not "one-size-fits-all" standardized products but are segmented based on "industry needs", including ready-to-use standardized products and in-depth customized solutions. The following introduces three core series:
The core requirements for TFT LCDs in industrial scenarios are "stability, anti-interference, and resistance to harsh environments". Reshine’s industrial-grade TFT LCD series is represented by the 21.5-inch RXL215090-C and 7-inch industrial screens. The 21.5-inch RXL215090-C has dimensions of 795.6mm×292.2mm×10.35mm and a visible area of 476.64mm×268.11mm. With a brightness of 900 nits and a reinforced metal housing, it has strong anti-vibration capability, suitable for installation on control cabinets of production lines ; the 7-inch industrial TFT LCD supports waterproof design (IP65 grade), with a surface that can withstand alcohol wiping, adapting to industrial scenarios such as food processing and pharmaceutical production that require frequent disinfection. Meanwhile, its linearity is ≤1.5%, ensuring precise touch operation.
Medical equipment has concentrated requirements for TFT LCDs: "high resolution, low power consumption, and easy disinfection". Reshine’s customized TFT LCD series for the medical industry has a minimum resolution of 1280×720, ensuring clear display of details such as waveforms and text; adopting low-power design, it consumes 20% less power than ordinary TFT LCDs, suitable for portable medical equipment (such as blood glucose meters and ECG monitors); the surface is coated with anti-fingerprint (AF) material to reduce fingerprint residue and can withstand wiping with disinfectants such as alcohol and iodophor to avoid cross-infection . For example, Reshine customized a 10.1-inch medical TFT LCD for a medical equipment manufacturer, which not only meets the above requirements but also obtained CE medical certification, complying with global medical equipment standards.
Consumer electronics and embedded projects (such as smart homes, maker projects, and in-vehicle central controls) require "easy integration and high adaptability" of TFT LCDs. Reshine has launched TFT LCD products compatible with mainstream platforms such as Raspberry Pi, Arduino, and ESP32. For example, the 10.1-inch TFT LCD (equipped with a capacitive touchscreen) is specifically designed for Raspberry Pi, providing driver files and sample codes, enabling makers to complete integration within 1 hour; the 7-inch TFT LCD supports HDMI interface, directly connecting to smart home central control motherboards. Meanwhile, Reshine can customize silk-screen printing (such as customer logos and operation button icons) to fit the appearance design of consumer electronic products.
Many customers delay project progress due to "lack of parameter knowledge" or "unclear needs" when selecting TFT LCDs. Reshine Display provides a full-process selection service covering "demand analysis - solution recommendation - sample verification - mass production delivery" to solve customers’worries.
In the demand analysis stage, Reshine’s engineers will clarify core needs through systematic questioning within 24 hours of receiving inquiries. The "five key questions" include: 1. What is the product application scenario? (Industrial/Medical/Consumer Electronics); 2. What size of TFT LCD is needed? (2.4 inches-32 inches optional); 3. What is the interface type of the main control equipment? (LVDS/MIPI/HDMI, etc.); 4. What are the temperature/humidity and light conditions of the usage environment? (Whether wide temperature or high brightness is required); 5. Is a touchscreen needed? (Capacitive/Resistive, Air Bonding/Optical Bonding). These questions help quickly lock in core parameters and avoid "blind selection".
In the solution recommendation stage, Reshine will provide 2-3 comparative solutions. For example, for an industrial customer needing a 7-inch TFT LCD, we recommend a standard solution of "LVDS interface + 900 nits brightness + IPS viewing angle" and a customized solution of "MIPI interface + 1500 nits brightness + wide temperature", explaining the cost and delivery cycle differences of the two solutions to help customers make trade-off decisions.
In the sample verification stage, Reshine can send samples within 12-15 days, along with technical documents (driver codes, wiring diagrams, test reports), enabling customers to complete sample verification within 1 week. If the sample does not meet requirements, Reshine’s engineers will adjust the solution for free. For instance, if a customer reports insufficient brightness of the 7-inch TFT LCD, we will adjust the backlight parameters within 3 days and resend the sample until the customer is satisfied.
In the mass production delivery stage, Reshine’s 10 precision production lines ensure a monthly capacity of 750,000 units, meeting customers’ bulk needs. Meanwhile, 20 quality inspectors monitor the entire production process – 10% of products in each batch are randomly selected for full-item testing including high-low temperature, vibration, and touch sensitivity tests to ensure consistent quality. In terms of logistics, Reshine supports express, sea, and air shipping, and can select Incoterms (such as EXW, FOB, CIF) according to customers’ needs for fast delivery worldwide.
