Import 3.0-3.5 Inch Tft Lcd Display — Buy in Bulk from Supplier in China

The 3.0-3.5 Inch TFT LCD Display from Conhui (Huizhou) Semi Conductor Ltd. is a compact transmissive colour display module built around thin-film transistor technology for active-matrix addressing. The unit carries an outline dimension of 45.04 mm x 77.0 mm and an active display area of 38.88 mm x 64.8 mm, giving a diagonal screen size in the 3.0-3.5 inch range. Pixel format is 240RGB x 320 (QVGA-class), which yields a square pixel arrangement suited to portrait-oriented handheld applications. The module integrates a white LED backlight for uniform luminance across the viewing area and is offered with a resistive or capacitive touch-panel option to support human-machine interface designs.

Glass substrate is typically alkali-free borosilicate (standard for TFT backplanes), with liquid-crystal material formulated for wide-temperature operation common in industrial and automotive grades. The 240RGB stripe configuration uses one red, one green and one blue sub-pixel per horizontal pixel triad, a standard arrangement for small-format panels. Viewing-direction parameters (optimised for 6 o'clock or 12 o'clock) and contrast ratio are determined by the rubbing angle and polariser stack, details that vary by specific variant. Typical operating temperature spans -20 °C to +70 °C for industrial-grade panels of this size, with storage temperature to -30 °C or -40 °C depending on LC formulation. Backlight lifetime is typically rated at 50 000 hours minimum to half-luminance at 25 °C.

Target buyers are OEMs and ODMs developing portable medical devices, industrial handheld terminals, automotive rear-seat entertainment modules and consumer GPS units. The 45 mm x 77 mm footprint suits designs where PCB space is constrained but readable colour graphics are required. Conhui's location in Huizhou, Guangdong Province, places it within the Pearl River Delta electronics manufacturing cluster, with access to upstream glass, driver IC and backlight supply chains. Buyers should confirm driver IC compatibility (commonly ILI9341, ST7789 or equivalent), interface type (8/16-bit parallel, RGB or SPI) and FPC connector pinout before committing to a PCB layout. Touch-panel integration, optical bonding and custom cover-lens services should be discussed at the sampling stage.

Conhui (Huizhou) Semi Conductor Ltd. is registered at Block 8, Aerospace Industrial Park, Huizhou, Guangdong Province, China. The company sits within the Huizhou Aerospace Industrial Park, a dedicated electronics manufacturing zone in the Pearl River Delta region. Its trust tier is marked as Harbour, though the response rate stands at 0.00% with zero recorded average response hours, indicating that direct communication data is not currently available through this channel. Buyers should treat engagement timelines as unverified and plan sourcing discussions accordingly.

The supplier's profile does not state year of establishment, employee count, annual turnover, production capacity, factory floor space, or named clients, and none should be inferred. The listing positions Conhui as a source of small-format TFT LCD modules with custom touch-panel integration capability. Given the Aerospace Industrial Park address, the firm likely shares the zone with aerospace-electronics and precision-component manufacturers, suggesting supply-chain proximity to glass-substrate, driver-IC and LED backlight vendors. Buyers are advised to request a factory audit, ISO 9001 certificate scope and customer references directly from Conhui before placing volume orders.
