Many of these use Segment LCDs, which serve as critical user interfaces in devices like electric potential therapy instruments. This article introduces the basic concept of electric potential therapy devices and the application and sizing characteristics of Segment LCDs in such equipment. 1. What is an Electric Potential Therapy Device? An electric potential therapy device uses a high-voltage, low-current electric field for therapeutic purposes. It is commonly used in rehabilitation and physical therapy to alleviate pain, improve blood circulation, and relax muscles through targeted electrical stimulation. These systems may include a main unit, remote controller, treatment chair, electrode plates (e.g., head or foot electrodes), conductive pads, localized treatment pens, and remote controls. In China, these devices are regulated by the NMPA (National Medical Products Administration) and classified as Class II or III medical devices, requiring corresponding registration certification (e.g., “国械注准”). 2. Role of Segment LCDs in Medical Devices A Segment LCD is designed to display numbers, simple characters, and fixed symbols. Unlike dot-matrix screens (e.g., smartphones or computers), it consists of pre-defined segments that can be individually turned on/off (similar to a calculator display). 2.1 Why Are Segment LCDs Preferred in Medical Devices? Segment LCDs are widely used in medical devices like potential therapy instruments due to their: Low power consumption: Ideal for portable or long-operation devices. High readability: Clear display under various lighting conditions (including bright environments). Stability & reliability: Wide operating temperature range (e.g., -20°C to 70°C). Cost-effectiveness: Affordable for fixed display requirements. Customizability: Tailorable display content and form factor for specific device designs. 2.2 Display Content on Electric Potential Therapy Devices Segment LCDs may show: Treatment time (countdown/stopwatch) Therapy intensity/energy level Selected treatment mode Device status (e.g., active, paused, error alerts) Battery indicator (for portable devices) 3. Key Sizes and Parameters for Segment LCDs Segment LCD specifications are highly customizable based on device models and design needs. Common parameters include: Parameter Typical Specifications/Options Screen Size Ranges from small (e.g., 35.0×20.0 mm) to large (e.g., 144.0×104.0 mm) Display Type TN (Twisted Nematic) Display Effect Positive: yellow/black, yellow-green/black, white/gray; Negative: blue/white, black/white, black/orange (blue/white common in medical devices) Operating Voltage 3V or 5V Interface Parallel, serial; FPC connection customizable Viewing Direction e.g., 6 o’clock Operating Temperature -20°C to +70°C Backlight LED (white, blue, green, etc.) for low-light readability Customization Highly customizable: content, size, connection (Zebra strip/FPC), pin spacing, contrast adjustment (software/potentiometer) *Note: Specifications vary by manufacturer and device requirements. For example, a gynecological therapy device may use a 240×128 dot matrix LCD with dimensions 144.0×104.0×14.0 mm, blue/white negative display, and a T6963C controller with parallel interface.* 4. Customization and Supplier Selection Due to the specialized nature of medical devices, Segment LCDs often require high customization. Manufacturers collaborate closely with specialized LCD suppliers. The customization process includes: Requirement definition: Display content, size, optical effects, electrical parameters, environmental tolerance. Design optimization: Schematic and layout design by engineers. Sample validation: Prototyping and testing. Production and delivery: Mass production with ensured timelines. Supplier selection criteria include product quality, production efficiency, delivery speed, and technical support. 5. Future Trends While advanced displays (e.g., high-resolution TFT or dot-matrix screens) are increasingly used in high-end health management devices for richer interfaces, Segment LCDs remain relevant for single-function, reliability-focused, and cost-sensitive devices like electric potential therapy instruments. Their stability, clarity, low power consumption, and customizability ensure continued importance in medical applications. Summary Segment LCDs are key components in the human-machine interface of medical devices like electric potential therapy instruments. Their low power consumption, high readability, reliability, and customizability ensure clear and accurate communication of critical information to operators and patients. Though based on mature technology, their deep integration with medical device functionality continues to make them indispensable in healthcare. This overview aims to enhance understanding of electric potential therapy devices and the Segment LCDs that support their operation.

Here is a detailed introduction: Definition and Principle Principle: It utilizes the change in the arrangement of liquid crystal molecules under the action of an electric field. The liquid crystal material twists the propagation of light under the action of the electric field, thus realizing image display. Definition: The segment code liquid crystal display, also known as pattern LCD, pen segment LCD, or monochrome LCD, is a type of LCD product. It controls the on - off state of each segment by applying a voltage between the "segment electrode" (SEG) and the "common electrode" (COM) of the liquid crystal, so as to display different characters, numbers, and graphics. Characteristics Low - cost: The manufacturing process is relatively simple, with low production costs, which helps reduce the overall cost of beauty instruments. Low - power consumption: It has low power consumption, which is beneficial for beauty instruments powered by batteries, enabling longer - lasting use. Simple and Intuitive Display: It can simply and clearly display information such as working status, parameter settings, and battery levels of beauty instruments, which is convenient for users to operate and view. Types TN (Twisted Nematic) Liquid Crystal Screen: It has a fast response speed and low manufacturing cost, but a relatively narrow viewing angle, usually around 50 degrees. It is commonly used in simple electronic devices such as calculators and remote controls, and is also applicable to some beauty instruments with lower requirements for the viewing angle. HTN (High Twisted Nematic) Liquid Crystal Screen: Its viewing angle is slightly wider, the contrast is improved, and the power consumption is low. It is often used in some simple instruments and meters, and is also one of the choices for beauty instrument segment code liquid crystal displays. STN (Super Twisted Nematic) Liquid Crystal Screen: The ability to display complex graphics and text is enhanced, but the response time is longer. It was previously widely used in electronic dictionaries, early mobile phones, etc., and can also be applied to beauty instruments that need to display more complex information. FSTN (Film Compensated Super Twisted Nematic) Liquid Crystal Screen: It has a high contrast ratio and a wide viewing angle, and is often used in multifunctional electric meters, power detection instruments, and some high - end beauty instruments that have certain requirements for display effects. Application in Beauty Instruments Hair - styling Beauty Instruments: Such as 烫发夹,直发器,etc. The segment code liquid crystal display can display temperature, time and other parameters to help users accurately control the styling process. Skin - care Beauty Instruments: Such as facial - lifting devices, acne - removing devices, etc. It can display working modes, intensity levels, and remaining battery power, allowing users to adjust the usage according to their own needs.

.gtr-container { font-family: Arial, sans-serif; color: #333333; line-height: 1.6; max-width: 800px; margin: 0 auto; padding: 15px; } .gtr-heading { font-size: 18px !important; font-weight: bold; color: #1a5276; margin: 20px 0 10px 0; border-bottom: 2px solid #3498db; padding-bottom: 5px; } .gtr-paragraph { font-size: 14px !important; margin-bottom: 15px; text-align: justify; } .gtr-feature-list { font-size: 14px !important; margin-left: 20px; padding-left: 0; list-style-type: disc; } .gtr-feature-list li { margin-bottom: 8px; } .gtr-highlight { background-color: #f8f9fa; padding: 15px; border-left: 4px solid #3498db; margin: 15px 0; } .gtr-keyword { font-weight: bold; color: #2874a6; } Les écrans TFT tactiles résistifs, avec leur forte capacité anti-interférence, leur prise en charge du toucher avec n'importe quel objet (y compris l'utilisation avec des gants) et leur coût modéré, occupent une position irremplaçable dans de nombreux domaines professionnels, particulièrement adaptés aux environnements difficiles ou aux scénarios d'opération de haute précision. Le domaine du contrôle industriel est leur principal scénario d'application. Sur les machines-outils CNC et les panneaux de contrôle PLC en usine, les écrans TFT tactiles résistifs (généralement de 5 à 10,1 pouces) peuvent résister à la pollution par l'huile et la poussière. Les opérateurs peuvent toujours cliquer précisément sur les boutons ou faire glisser pour ajuster les paramètres, même en portant des gants. Par exemple, les écrans d'affichage aux postes d'assemblage sur une chaîne de production automobile doivent fonctionner de manière stable dans un environnement de vibrations mécaniques et de poussière métallique. La structure scellée de l'écran résistif (avec un niveau de protection IP65) peut résister efficacement aux interférences externes et assurer la saisie précise des instructions de production. Les écrans TFT tactiles résistifs sont largement utilisés dans les terminaux de point de vente (POS) et les systèmes de commande dans les secteurs de la vente au détail et de la restauration. Lorsque les caissiers opèrent avec leurs ongles ou des stylos spéciaux, l'écran peut répondre rapidement, et sa fonction anti-rayures convient à une utilisation à haute fréquence (des milliers de touches par jour). Dans l'écran de commande de cuisine, dans un environnement de vapeur à haute température, la performance d'étanchéité à l'humidité des écrans résistifs est supérieure à celle des écrans capacitifs, ce qui peut empêcher les défaillances tactiles causées par la vapeur d'eau. On les retrouve également fréquemment dans le domaine des équipements médicaux, tels que les panneaux de commande des pompes à perfusion et des moniteurs. Lorsque les médecins ou les infirmières portent des gants en caoutchouc pour opérer, l'écran résistif peut reconnaître de manière fiable les instructions tactiles, et sa surface peut résister à la désinfection à l'alcool (essuyée plusieurs fois par jour) sans dégradation des performances. De plus, dans les terminaux libre-service extérieurs (tels que les bornes de paiement et les bornes de renseignements), les écrans résistifs peuvent fonctionner normalement dans des environnements à basse température et pluvieux, répondant aux exigences d'utilisation par tous les temps. Bien que les écrans capacitifs aient été remplacés dans l'électronique grand public comme les téléphones mobiles et les tablettes, la praticité des écrans TFT tactiles résistifs dans les domaines professionnels reste irremplaçable.
