Description

Model: PO204RT448S

The 2.04-inch AMOLED Display delivers vivid, high-contrast visuals for smartwatch and wearable devices where a compact form factor and crisp UI matter. With a 368 × 448 resolution and 16.7M colors (24-bit), it renders clean text, icons, and watch-face graphics at 284 PPI, supporting a refined look on small screens.

This module is designed for efficient integration, supporting a QSPI interface and a typical 45 Hz frame frequency for smooth everyday interactions. It features a 700 cd/m² (typ.) luminance and wide viewing performance (88° in all directions at CR ≥ 200), helping maintain consistent readability from different angles. With a 39.98 × 33.74 mm active area in a compact 44.46 × 34.64 × 2.58 mm outline, it fits space-limited wearable enclosures. Gesight supplies this display with the CH13613-35XKA_R0 built-in driver IC (COF) and an on-cell touch solution using the CHSC6417 touch IC via FPC connection, rated for -30 to +70℃ operating and -30 to +80℃ storage temperatures.

Compact On-Cell Touch Structure for Wearable Integration

This on-cell touch AMOLED module is engineered for clean, space-saving integration in smartwatch and wearable enclosures. The front side features a rounded-corner active window suited to watch-face layouts, while the back side shows a compact FPC layout designed to reduce internal footprint and simplify assembly. The integrated touch structure keeps the module thin and streamlined, helping product teams maintain a slim device profile while ensuring stable electrical connection to the mainboard.

For prototyping and fast validation, Gesight can also provide a compatible controller board solution to speed up evaluation and shorten the development cycle.

FAQ

Where can I buy this display？

If you just need a few samples, it`s better to directly on our Aliexpress store, we are 5 stars feedback supplier with 100% Honesty. (The buy link is on the right of the product image)
For bulk orders, it`s better to contact us and get a better price. 

Different displays have different characteristics, just tell Gesight Display your application, and operating environment, Gesight Display will suggest a suitable display for you.

Gesight Display provide HDMI/Type-C controller board or individual demo kit to test.
The pictures of demo kit can be changed by yourself. 

Gesight Display will provide necessary specifications for most LCD/OLED on sale, including,
Display Datasheet
Display Drawing
IC Datasheet
Circuit schematic
For most electronics engineers, our specifications are enough to run the display, and we will provide some assistance.
But Gesight Display is not a school, if customers don`t know the basic knowledge to design circuit boards, we suggest using our controller board to drive the display.

First, you need to check whether this display has On-cell or In-cell touch panel, if has, it only needs to add a cover glass on it. If not, it needs an external touch panel.
(On-cell and In-cell are integrated PCAP touch panels on the display screen)
Because the shape of the cover glass depends on the design of the clients, to avoid infringement of appearance,  most of the developers need different customized touch panels.
Gesight Display can provide a customized touch screen with a low cost of tooling charge.

1. UPS/Fedex/DHL/TNT, the best choice for most clients, 3~7 days to arrive.
2. Aliexpress standard ship, this way is cheap and slow, usually take more than 10 days. Only for samples.
3. For Russian clients, EMS or Aliexpress shipment is better.
4. Any designated logistics are acceptable
 

Most display panels are from giant manufacturers such as BOE, Sharp, LG, EDO, AUO, etc. They have already tested with strict standards.
For OEM products from Panox Display factory, please check the quality test standards.   

The lifetime is different on different images, check the lifetime on datasheet to study it. 

If your Raspberry Pi can support the interface of the display panel, and you know how to program on Raspberry Pi, you can connect to our display.
If you don`t know or don`t want to write a display program on Raspberry Pi, it`s better to get an HDMI controller board from us, and Panox Display will send a config.txt file for reference.

Panox Display offers the following specifications for most LCD/OLED products:

  • Display datasheet

  • Mechanical drawing

  • IC datasheet

  • Circuit schematic

Readable Under Sun

Compare to LCD, OLED has many advantages as follows:

Thin Like Paper:More than 50% thinner and lighter than LCD, creating an edgy form factor in style.

Green Power:Clock-mode standby can be up to 60 hours, much lower consumption compare to LCD displays.

"Wow" Effect:High contrast ratio and wide color gamut offer sharp and vivid image, and consistent display from any angle.

OLED Type Structures

        OLED driver as well as two divided into passive (PMOLED) active (AMOLED), which PMOLED simple structure, each pixel is represented by a separate cathode and anode control, no additional driver circuit, but too much control lines restrict its application of high-resolution large screen; AMOLED entire cathode surface electrode via a drive circuit driving the light emitting anode, significantly reducing the number of control lines, it has a low-power, high-resolution, fast response and other characteristics, AMOLED therefore gradually become the mainstream OLED display.
