The AT056TN53 V.1 from Chimei Innolux is a 5.6-inch a-Si TFT-LCD panel featuring an integrated WLED backlight with built-in LED driver, distributed by Tonya Display Limited from Shenzhen, China. It resolves 640(RGB)x480 (VGA) in 4:3 aspect ratio with RGB vertical stripe pixel geometry, and uses a 6-bit grey scale signal per dot for a 262K colour palette at 50% NTSC colour gamut. Brightness reaches 350 cd/m² typical with 500:1 transmissive contrast, while the TN, normally white, transmissive LCM offers 70/70/50/70 (Typ.)(CR≥10) viewing angles with 6 o'clock best view direction. Response time is 10/15 ms (Typ.)(Tr/Td), and the typical vertical frame rate is 60 Hz.
Physically, the active area measures 112.896(W) x 84.672(H) mm within an outline of 126.5(W) x 100(H) mm, with a viewing area of 115.90(W) x 87.67(H) mm and antiglare surface treatment. Net weight is notably lighter at 83.1 g typical, achieved through design optimisation compared to earlier revisions. The edge-lit WLED backlight rates 20,000 hours lifetime. Unlike its counterpart, this variant includes the LED driver internally, simplifying integration. Signal input uses parallel RGB (1 ch, 6-bit) via a 40-pin FPC connector with single 3.3 V (Typ.) supply voltage for VCC.
The integrated driver and single-voltage operation make this panel-carousel panel attractive for portable medical devices, handheld instrumentation, and cost-sensitive industrial HMIs where board space and power rail simplicity matter. The 350 cd/m² brightness suits indoor and moderate ambient applications. Buyers should note the 6-bit colour limitation versus 8-bit alternatives, evaluating whether 262K colours and 50% NTSC gamut meet their UI requirements. Confirm with Tonya Display Limited regarding driver interface compatibility and whether the 40-pin FPC matches their existing cable harnesses.

Tonya Display Limited operates from C1207, Niulanqian Building, Minzhi, Longhua, Shenzhen, Guangdong, 518000, China. The company carries a harbor trust tier with a 0.00% platform response rate and zero average response hours, indicating minimal reliance on automated messaging. Buyers should treat communication with this supplier as requiring direct outreach rather than expecting prompt online quotation turnaround. No factory size, year of establishment, or revenue figures are provided in the listing.
The firm's offering centres on Chimei Innolux small-format TFT-LCD modules, suggesting a trading or distribution model focused on branded panel supply to OEMs and system integrators. Its Shenzhen location in Longhua District provides proximity to component markets and logistics hubs. Buyers should ask Tonya Display Limited about inventory depth for the AT056TN53 V.1 specifically, whether they hold stock or broker factory-direct shipments, and what warranty coverage applies against dead pixels or backlight failure. Reference checks with prior buyers of Innolux panels are advisable given the limited verification signals.

Prior to placing an order for the AT056TN53 V.1 with Tonya Display Limited, validate that the V.1 revision corresponds to your approved vendor list and that the integrated LED driver matches your system architecture. Request the Final Ver01 datasheet referenced in the source, plus any engineering change notices subsequent to 2010. Verify that the 40-pin FPC pinout aligns with your host controller, and confirm whether Tonya provides sample cables or recommends a specific mating connector manufacturer such as Hirose or Molex.
For shipping and terms, note that Tonya Display Limited has not specified Incoterms, MOQ, or lead time. Typical practice for Shenzhen-based component traders is EXW or FCA Shenzhen for small orders, transitioning to FOB Shenzhen for volume. Payment structures often require wire transfer deposit with balance before shipment for unverified buyers, or documentary collection for established relationships. Given the 0.00% response rate, secure a proforma invoice with explicit product revision, quantity, unit price, and delivery schedule before issuing any payment, and consider using an escrow service for initial transactions.
Quality verification should include functional testing of the integrated LED driver across the full dimming range, pixel defect inspection against ISO 13406-2 or your customised acceptance criteria, and measurement of actual luminance and colour coordinates against the datasheet typicals. For incoming inspection, use a standard test pattern suite (full white, full black, RGB primaries, greyscale ramp) and document any mura, flicker, or driver-induced noise. Specify with Tonya Display Limited the acceptable defect class, return material authorisation process, and whether defective units are replaced or credited. For volume orders, pre-shipment inspection at the Shenzhen warehouse is prudent given the limited post-sale support signals.
