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.
