Shenzhen Qunmao Display Technology Co., Ltd., a professional source manufacturer of LCD panels with OEM/ODM capabilities, leverages its mature display technology and production expertise to launch the Qtenboard Smart Shelf Edge Display Series tailored for retail scenarios. Covering a comprehensive range of 23.1-inch to 37-inch bar-type displays, this series centers on "shelf space adaptation, stable durability, and intelligent easy management". It caters to the needs of commodity information display and marketing in various retail formats such as convenience stores, supermarkets, and fresh food stores, offering businesses efficient digital display solutions.

Retail shelves typically feature a "narrow and long" structure. The Qtenboard Smart Shelf Edge Display Series adopts a customized bar-type form, enabling flexible installation without modifying existing shelves. It covers diverse display scenarios:

Retail scenarios face lighting interferences such as direct ceiling lights and supplementary lights in fresh produce areas. The Qtenboard Smart Shelf Edge Display optimizes hardware parameters to ensure clear information visibility:

Display Parameter	Specific Specifications (by Size)	Practical Advantages
Brightness	23.1/24/35-inch: ≥300cd/㎡; 28/29/37-inch: ≥700cd/㎡	Low-brightness models suit regular lighting areas; high-brightness models counter strong light in supermarkets, avoiding "unclear due to reflection".
Contrast Ratio	23.1/35-inch: 3000:1; 24/28/29/37-inch: 1200:1	Text and price tags are sharp and clear; promotional slogans (e.g., "limited-time discount") stand out, improving information transmission efficiency.
Viewing Angle	All sizes: 178°(H)×178°(V)	Customers can view content clearly from any angle (front or side of the shelf) without color distortion or image blurring.
Resolution	23.1-inch: 1920×158; 24/28/37-inch: 1920×360; 29-inch: 1920×540; 35-inch: 2880×158	Matches the bar-type screen ratio to avoid text/image stretching; the 35-inch high resolution presents fine product textures.
Response Time	23.1-inch: 6ms; 28/29-inch: 8ms; 24-inch: 30ms; 35-inch: 9.5ms; 37-inch: 14ms	When playing short product videos (e.g., food preparation, outfit demonstrations), models with low response time (23.1/28/29-inch) have no motion blur.

1.3 Hardware Configuration: Ensuring Stable Retail Operation

• Core Chip:All sizes are equipped with the Rockchip PX30 quad-core ARM Cotex-A35 processor (1.5GHz main frequency) + Mali-G31 GPU, meeting multi-tasking needs (e.g., displaying product information and playing videos simultaneously).
• Storage & Expansion:Standard configuration: 1G DDR3 RAM + 8G EMMC internal storage (supports upgrades to 1G/2G RAM and 8G/16G/32G/64G storage). External storage supports up to 64G TF cards, enabling large-capacity storage of product images and video materials.
• Network & Interfaces:All sizes support 2.4G wireless WIFI; 4G module installation is optional to adapt to different store network environments. Interfaces include 1micro USB (OTG) and 1TF card slot (the 37-inch model additionally has 1RJ45 Ethernet port and 1USB). The 35/37-inch models support 12V DC power supply (must use the original adapter).
• Durable Structure:All sizes adopt a metal sheet shell + metallic paint surface treatment (23.1/24/28/29-inch: black, silver gray, custom color optional; 35/37-inch: black). It is scratch-resistant and resistant to minor collisions, adapting to frequent restocking operations. The surface is easy to clean—dust and stains can be wiped off with a damp cloth.

1.4 Intelligent Functions: Matching Retail Operation Workflows

• Content Update & Management:Supports networked remote content push (WIFI/4G); offline content update is available via TF card or OTG data cable, eliminating the hassle of "replacing paper price tags one by one". It supports multi-mode scheduling (time period, daily, weekly, monthly, cycle play), e.g., setting "fresh produce promotion in the morning and cooked food discount in the evening" for automated operation.
• Display & Interaction:All sizes support multi-split-screen display (e.g., combination of images, text, and clock). The screen area can be freely divided to combine videos, subtitles, weather forecasts, and other information. It supports infrared remote control operation, allowing store staff to turn on/off the device and switch content without close contact with the screen.
• Terminal Monitoring & Maintenance:Supports network-connected terminal monitoring, enabling remote viewing of device operation status (e.g., online status, command execution results). It also supports remote power-on/off, restart, and software upgrade, reducing on-site maintenance frequency.
• Power Supply & Power Consumption:All sizes support 100-240V (50/60Hz) wide voltage input. Power consumption ranges from ≤24W (23.1-inch) to ≤60W (37-inch), with standby power consumption ≤1W, meeting store energy-saving needs. It supports scheduled power-on/off, which can be set according to store business hours to avoid unnecessary power consumption.
