2.Shutdown time node
According to the production stoppage schedule of AU Optronics products and channel announcements:
time node | Matter |
Q1 2025 | AU Original Factory Issues Production Suspension Notice, Opening Last Order Window |
March 2025 | Last Time Buy (LTB) deadline |
Q3 2025 | G057QN01 V2 officially ceases production |
Starting from Q3 2025 | G057QAN01.1 Fully mass-produced, seamlessly connected |
Important notice: G057QN01 V2 has been officially discontinued and inventory is limited across all channels. For new projects, please directly adopt the alternative model G057QAN01.1. For old projects, it is recommended to evaluate the switch as soon as possible to avoid the risk of supply chain interruption.
3. Official upgrade alternative model: G057QAN01.1
3.1 Explanation of Substitution Relationship
G057QAN01.1 is the officially designated upgraded replacement model for G057QN01 V2 by AU, which will be fully mass-produced from Q3 2025 and seamlessly integrated with the discontinuation of G057QN01 V2.
The size, resolution, and interface pin definitions of the two models are completely identical, allowing for direct replacement and use.
3.2 Core Upgrade Points
Upgrade Item | G057QN01 V2 | G057QAN01.1 | Customer value |
Display technology | TN | AHVA(IPS level full view) | Side view without color deviation, enhancing the experience of multiple people viewing together |
Viewing angle | 80/80/70/70 | 89/89/89/89(Full perspective) | The perspective range has been greatly expanded |
Manufacturing process | G3.5 production line | G5 production line | More stable quality and guaranteed supply |
PCBA components | Original design | New optimized design | Better performance |
3.3 Change Points to Pay Attention to
Change item | G057QN01 V2 | G057QAN01.1 | Switching precautions |
Backlight cable | 6-wire interface | 2-wire interface | Need to confirm compatibility of backlight driver circuit |
Surface treatment | Foggy surface, 3H | Foggy surface, 3H | No change |
Overall dimensions | 144×104.6×12.8 mm | 144×104.6×12.8 mm | Exactly the same |
Mounting hole | 4-Φ2.6 | 4-Φ2.6 | Exactly the same |
Interface Definition | CMOS 33-pin | CMOS 33-pin | Fully compatible |
Switching prompt: The backlight cable of G057QAN01.1 has been changed from 6 wires to 2 wires. Please make sure to verify whether the existing backlight driver circuit supports a 2-wire interface when switching. If you need technical support, please contact our engineering team.
4. Alternative Switching Suggestions
For projects still using G057QN01 V2, it is recommended to complete the switch according to the following rhythm:
Stage | Time | Action recommendations |
Immediately | Upon receiving notification | Calculate the current inventory usage of V2 and evaluate the switching time point |
Week 1-2 | Alternative verification | Apply for G057QAN01.1 sample and complete compatibility testing |
Week 3-4 | Small-batch trial production | Trial production of 20-50 units to verify backlight driver compatibility |
Weeks 5-8 | Batch switch | Formally switch to G057QAN01.1 until V2 inventory runs out |
5.Application scenarios and selection value
Application field | Specific scenario | Why choose alternative models |
Outdoor terminal | Charging stations, express lockers, outdoor advertising machines | 800nit high brightness ensures visibility in sunlight |
In-vehicle display | Engineering machinery instruments, agricultural machinery navigation | -30~85 ℃ wide temperature range, suitable for outdoor operations |
Industrial HMI | Industrial control panel, automation equipment | 4: 3 classic ratios, universal TTL interface |
Military Industry/Security | Portable terminals and monitoring devices | Wide temperature range and high reliability |
6. Frequently Asked Questions (FAQ)
Q1: Can G057QAN01.1 directly replace G057QN01 V2?
Okay. The two have identical dimensions, mounting holes, resolution, and interface pin definitions, and can be directly replaced.
Q2: Do I need to change the circuit of the backlight cable from 6-wire to 2-wire?
Verification is required. The 2-wire backlight interface is simpler than the 6-wire interface, but it is necessary to confirm whether the output voltage and current of the existing backlight driver circuit match. We can provide technical support to assist in the evaluation.
Q3: What is the brightness of G057QAN01.1?
The brightness of both models is 800 cd/m ², and the visual effect under sunlight is completely consistent.
Is the perspective of G057QAN01.1 really better?
Yes. V2 adopts TN technology with a viewing angle of 80/80/70/70; V1 has been upgraded to AHVA full view technology, achieving 89/89/89/89 full view and significantly improving display performance.
Q5: Can G057QN01 V2 still be purchased in stock?
Some channels may still have a small amount of leftover inventory, but the quantity is limited. Suggest using G057QAN01.1 directly for new projects and switching to old projects as soon as possible to avoid supply chain interruption risks.
What is the supply cycle and minimum order quantity for G057QAN01.1?
G057QAN01.1 is a mass-produced model from AU, with stable supply. Please consult customer service or sales representative for specific minimum order quantity and delivery time.
