Applications:
1. Industrial Control Field
In the industrial control field, the CH700WX08A module is an ideal choice for equipment operation interfaces and status monitoring displays. Its 7-inch long strip form factor perfectly fits the narrow installation spaces of industrial control panels, such as those on assembly line control cabinets, mechanical equipment operation consoles, and intelligent sensor monitoring terminals. With a wide operating temperature range of -20 ~ +70 ℃, it can work stably in harsh industrial environments with large temperature fluctuations, like high-temperature workshops or cold storage auxiliary control systems. The 500 cd/m² high brightness ensures that operators can clearly read real-time data (such as production counts, pressure values, and speed parameters) even under the strong light of factory workshops, and the IPS technology with 80/80/80/80 viewing angles allows multiple staff members around the equipment to check the display content simultaneously without visual dead angles.
2. Automotive Electronics Field
For automotive electronics, this module is widely applicable to automotive instrument clusters and in-car control interfaces. The elongated display shape matches the layout of modern car dashboards, enabling it to display key driving information (such as speed, fuel level, and engine speed) in a concentrated manner while leaving space for other functional components. Its excellent high-temperature resistance (-20 ~ +70 ℃ operating temperature) ensures stable performance even when the car is parked in direct sunlight or during long-term high-speed driving, avoiding display failures caused by high temperatures. Additionally, the integrated touch panel simplifies the operation of in-car functions, allowing drivers to adjust air conditioning, audio, and navigation settings through the touch screen without distracting from driving, enhancing the convenience and safety of in-car operations.
3. Smart Home and Digital Signage Field
In the smart home sector, the CH700WX08A is suitable for smart home control panels installed on walls or furniture surfaces. Its long strip design can be easily integrated into narrow spaces (such as beside door frames or on the edge of cabinet panels), serving as a centralized control terminal for home appliances (controlling lights, curtains, air conditioners, etc.). The 16 million color display capability presents rich and vivid interface icons and status indicators, making the operation interface more intuitive and user-friendly. In the digital signage field, it is used in small-sized, elongated digital signs, such as advertising displays in elevator doors, product information boards in retail store shelves, and menu boards in fast-food restaurants. The high brightness of 500 cd/m² ensures that the displayed advertisements, product details, or menus remain clearly visible even in well-lit indoor environments, attracting the attention of passers-by and improving the communication effect of information.
FAQ:
Q: What is the lifespan of the backlight in the CH700WX08A module under normal operating conditions?
A: Under normal operating conditions (operating temperature: -20 ~ +70 ℃), the backlight of the CH700WX08A module has a typical lifespan of 50,000 hours. This lifespan may vary slightly depending on factors such as actual usage time, ambient temperature stability, and voltage stability.
Q: What is the warranty period for the CH700WX08A module, and what situations are not covered by the warranty?
A: The CH700WX08A module has a standard warranty period of 12 months from the date of delivery. The warranty does not cover damages caused by improper operation (such as incorrect voltage connection), unauthorized disassembly or modification of the module, natural disasters (such as floods, earthquakes), or long - term use beyond the specified operating temperature range.
Q: If a customer receives a batch of CH700WX08A modules with appearance defects (such as scratches on the touch panel), what is the after - sales processing process?
A: First, the customer needs to take photos or videos of the defective modules to confirm the defect situation, and send the relevant materials together with the order number and delivery note to our after - sales email within 7 days of receiving the goods. Our after - sales team will reply within 2 working days. After confirming the non - man - made defects, we will arrange for replacement of the defective modules, and the transportation costs for the replacement will be borne by our company.
Q: Can the technical support team of Chenghao Optoelectronic provide on - site technical guidance for the CH700WX08A module if customers encounter difficulties in the assembly process?
A: Generally, we first provide remote technical guidance through online communication tools (such as Zoom, WeChat) or phone calls. Our technical engineers will explain the assembly points and solutions to problems in detail. If the remote guidance cannot solve the problem, and the customer's order quantity reaches 500 pieces or more, we can arrange on - site technical guidance after confirming the time and location with the customer. The travel and accommodation expenses of the on - site engineers will be negotiated and confirmed separately according to the actual situation.
