LM10V322 FOR SHARP 10.4-inch 640*480 LCD display panel

Sharp LM10V322 10.4-Inch CSTN Color LCD Panel

The LM10V322 is a 10.4-inch CSTN (Color Super Twisted Nematic) LCD display module manufactured by Sharp Corporation . Sharp is a renowned Japanese multinational corporation known for its electronics and display technologies. The LM10V322 is part of Sharp's industrial LCD module lineup, designed for applications requiring a compact color display with a standard VGA resolution interface. The closely related model LM10V332 shares the same 10.4-inch VGA platform and its official Sharp datasheet provides the most detailed specifications for this platform.

Important Data Conflict: The invshop listing contains an internal inconsistency — the main product title states "10.4-inch 640*480" while the invshop product detail section at the bottom lists "Panel size: 5.7 inch, Resolution: 320*240". These are fundamentally different display specifications. The 10.4-inch 640x480 VGA configuration is consistent with the Sharp LM10V-series platform (confirmed by the official Sharp LM10V332 datasheet from beyondinfinite.com and manualmachine.com) and is supported by multiple application examples on industrial automation sites. The 5.7-inch 320x240 resolution appears in the invshop detail table but not in any external reference for the LM10V322 model number. Buyers should confirm the exact panel size and resolution with the seller before purchasing.

About Sharp Corporation — LCD Division

Sharp Corporation , headquartered in Sakai, Osaka, Japan) is a Japanese multinational corporation renowned for its electronics, home appliances, and display technologies. Sharp pioneered many flat-panel display technologies and was one of the founding companies of the modern TFT-LCD industry. Sharp's LCD modules were widely used in industrial equipment, consumer electronics, and automotive applications from the 1990s through the 2000s. In 2016, Sharp was acquired by Foxconn (Hon Hai Precision Industry Co., Ltd.), becoming a subsidiary of the world's largest electronics contract manufacturer. Sharp continues to develop and manufacture display products including LCD modules, OLED displays, and electronic components under the Foxconn umbrella.

Display Technology: CSTN (Color Super Twisted Nematic)

The LM10V322 uses CSTN (Color Super Twisted Nematic) LCD technology:

• CSTN vs. Monochrome STN: CSTN is the color version of STN LCD technology. Like monochrome STN, it uses super-twisted nematic liquid crystal molecules to achieve higher contrast and faster response than standard TN panels. CSTN adds an RGB (Red-Green-Blue) color filter layer to produce full-color displays — each pixel is divided into three sub-pixels (R, G, B) that combine to produce 262,144 colors (18-bit color depth).

• VS. TFT: CSTN panels use a passive matrix addressing scheme, while TFT (Thin Film Transistor) LCDs use an active matrix with a transistor at each pixel. TFT panels offer faster response times, higher contrast ratios, and wider viewing angles than CSTN. However, CSTN panels are less expensive to manufacture and were widely used in mid-range industrial and consumer applications before TFT pricing dropped.

• CCFT Backlight: The LM10V322 uses a Single Cold Cathode Fluorescent Tube (CCFT) backlight. CCFT backlights provide bright, even illumination but have been largely superseded by WLED (White LED) backlights in modern displays due to WLED's longer lifespan, lower power consumption, instant on capability, and mercury-free construction.

• VGA Resolution (640x480): The 640x480 resolution (known as VGA, Video Graphics Array) was the standard display resolution for small-to-medium LCD panels from the 1990s through the 2000s. At 10.4 inches diagonal, the dot pitch is approximately 0.33mm x 0.33mm per color sub-pixel — large enough for industrial legibility but low by modern standards.

Technical Specifications

Data Conflict — Critical Buyer Advisory

The invshop listing for product 36291 contains an irreconcilable internal data conflict that buyers must resolve before ordering:

• Main Title: "LM10V322 FOR SHARP 10.4-inch 640*480 LCD display panel" — states 10.4 inch, 640x480 resolution

• Invshop Detail Table: "Panel size: 5.7 inch; Resolution: 320*240; Panel Type: TFT" — these are completely different display specifications

The 10.4-inch 640x480 VGA configuration is confirmed by the official Sharp LM10V332 datasheet (which shares the same 10.4-inch platform) and by multiple industrial automation distributor listings referencing the LM10V322 or LM10V332 at 10.4 inches. The 5.7-inch 320x240 specification in the detail table does not appear in any external reference for the LM10V322 model. The weight listed in the detail table is 1.000kg, while the official Sharp datasheet for the 10.4-inch platform specifies 450g. Buyers must contact the seller to confirm which specification is correct before placing an order.

Weight Data Note

The invshop listing shows a weight of 1.000 kg. However, the official Sharp datasheet for the 10.4-inch LM10V332 platform lists the weight as approximately 450g. The discrepancy may be related to the internal data conflict described above. If the 10.4-inch 640x480 configuration is correct, the actual weight should be approximately 450g. For the alternative 5.7-inch 320x240 configuration, a weight check with the seller is recommended.

Applications

• Industrial HMI (Human Machine Interface): Color display modules for factory automation control panels, PLC interfaces, and SCADA terminal displays. The VGA resolution and 10.4-inch size were standard for mid-range industrial HMIs from the 1990s-2000s.

• Medical Device Displays: Patient monitoring equipment, diagnostic instruments, and medical imaging terminals where Sharp LCD modules have historically been specified for their reliability and quality.

• Injection Molding Machine Screens: The invshop listing specifically mentions "injection molding machine screen" as a key application, indicating this panel may be used as a replacement part for legacy injection molding equipment control panels.

• Automotive Displays: In-vehicle entertainment, navigation systems, and dashboard instrumentation from the era when Sharp was a major automotive display supplier.

• Point-of-Sale (POS) Terminals: Retail checkout displays and self-service ordering terminals requiring a compact color display.

• Navigation LCD: Marine and automotive navigation equipment displays.

• Legacy Equipment Replacement: The LM10V322 is a legacy part — suitable for maintaining and repairing older industrial equipment that requires the specific 10.4-inch VGA Sharp LCD module as a replacement spare.

Integration Considerations

• Logic Voltage: The panel requires a 5.0V logic supply. Designers must ensure the host system provides the correct voltage and power (310mW typical).

• CCFT Backlight Replacement: The CCFT (Cold Cathode Fluorescent Tube) backlight has a finite lifespan of approximately 15,000-25,000 hours. For long-term deployments, the CCFT may eventually require replacement — a specialized repair procedure.

• Passive Matrix Limitations: The CSTN passive matrix display has slower response times (300ms) and narrower viewing angles compared to modern active matrix TFT displays. Fast-motion video may show ghosting, and optimal contrast requires viewing the display within the specified viewing cone.

• VGA Interface Timing: The panel uses standard VGA-resolution timing (640x480 at 60Hz), compatible with standard graphics ICs and embedded display controllers that support VGA output.
