The Sony ECX335B is a 3.5-inch TFT LCD display module with 480×320 pixel resolution, 450 cd/m² brightness, and a 500:1 contrast ratio. Designed for industrial applications, it supports LVDS interfaces and operates at -20°C to 70°C. Panox Display supplies OEM variants with custom touch panels and anti-glare coatings, optimized for medical devices and embedded systems. Pro Tip: Pair with a compatible controller board to avoid signal mismatch.
What Is Tandem OLED & Why It’s Important
What resolution does the Sony ECX335B offer?
The Sony ECX335B delivers 480×320 (HVGA) resolution at 167 PPI. Its 18-bit color depth ensures smooth gradients for GUIs. Ideal for HMI panels, this clarity allows crisp text/graphics even in low-light industrial settings.
Beyond pixel count, the ECX335B uses RGB stripe sub-pixel arrangement to enhance color accuracy. Pro Tip: For video playback, enable dithering to mitigate 18-bit limitations. Real-world example: In POS systems, this resolution accommodates multi-language menus without aliasing. But how does it compare to similar displays?
| Model | Resolution | Use Case |
|---|---|---|
| Sony ECX335B | 480×320 | Industrial HMIs |
| Panox PX350A | 640×480 | Medical Imaging |
| Sharp LQ035Q7 | 320×240 | Basic Instrumentation |
Why is brightness critical for the ECX335B?
With 450 cd/m² brightness, the ECX335B remains visible under direct sunlight. This exceeds consumer-grade displays (200–300 cd/m²), aligning with industrial usability standards.
High brightness combats ambient glare in outdoor kiosks or factory floors. Panox Display enhances this with anti-reflective coatings, reducing washout by 40%. Practically speaking, a 450 cd/m² display draws 20% more power than 300 cd/m² panels—plan thermal management accordingly. For example, solar-powered systems might opt for dimmer backlights during midday peaks. Why not use maximum brightness always? Heat buildup risks LED degradation beyond 70°C.
| Brightness | Power Draw | Use Case |
|---|---|---|
| 450 cd/m² | 2.8W | Outdoor HMIs |
| 300 cd/m² | 2.1W | Indoor Retail |
| 600 cd/m² | 3.5W | Aviation |

How does the LVDS interface benefit industrial use?
The LVDS interface in the ECX335B reduces EMI noise, critical for factories with motor drives or welding equipment. It supports 24-bit color transmission over thin cables, simplifying cabinet wiring.
Unlike parallel RGB, LVDS uses differential signaling to maintain signal integrity across 15-meter runs. Panox Display’s custom ECX335B variants include shielded LVDS cables resisting 50V/m interference. For example, in CNC machines, this prevents screen flickering near servo motors. But what if your MCU lacks LVDS? Add a $12 LVDS converter IC like SN75LVDS83A. Transitional systems can bridge legacy TTL signals without hardware redesigns.
Can the ECX335B withstand extreme temperatures?
Yes, the -20°C to 70°C operating range ensures reliability in freezing warehouses or desert solar farms. Its wide-temperature TFT layer prevents black smearing during rapid thermal shifts.
The ECX335B employs ITO-heated glass (optional via Panox Display) to prevent condensation below 0°C. Pro Tip: Avoid abrupt temperature changes—thermal shock cracks solder joints. For example, railway displays using ECX335B modules survive -30°C winters when heated gradually via PWM-controlled pads. Transitional startups should preheat displays in sleep mode before full operation.
Is touchscreen integration supported?
Panox Display offers resistive or capacitive touch add-ons for the ECX335B. The 4-wire resistive variant supports gloved inputs, while projected capacitive enables 10-point multitouch.
Integrating touch requires a separate controller (e.g., FT5336G) and increases power draw by 0.3–0.8W. Real-world example: Medical infusion pumps use Panox’s 5mm-thick resistive overlay for stylus-based dose input. Warning: Avoid capacitive screens in high-humidity environments—false touches occur at >85% RH. Transitioning from resistive? Budget for UI responsiveness testing—capacitive requires recalibrated debounce times.

FAQs
Yes—we integrate 4-wire resistive or PCAP touchscreens, tested for 1M+ actuations. Custom bezel cuts available for IP65 sealing.
Can I replace a Sharp LQ035Q7 with the ECX335B?
Only with pinout adjustments—ECX335B uses LVDS vs. Sharp’s parallel RGB. Our adaptor kits simplify retrofits.
What’s the ECX335B’s typical lifespan?
50,000 hours at 25°C. High temps halve lifespan; our heated glass modules mitigate this.
Is sunlight-readable coating optional?
Yes, but Panox recommends it for outdoor use—reduces reflectivity by 72% without color shift.
Are driver boards included?
Sold separately. We provide open-source Linux drivers for Raspberry Pi and BeagleBone.
