5.Frequently Asked Questions (FAQ)

Q1: Can G070VW01.012 directly replace G070VW01 V0?

Okay. The two have identical external dimensions, interface pin definitions, and electrical parameters, and can be directly replaced without the need to modify hardware and software. 

Q2: What are the changes in display effect after replacement?

Significant improvement. The main upgrades include: 

Viewing angle: increased from 80 ° to 89 ° full view angle (IPS level)

Contrast ratio: increased from 500:1 to 1000:1 (increased by 100%)

Response time: increased from 30ms to 20/10ms

Color Depth: Supports FRC for smoother color transitions 

Q3: Will brightness and resolution change?

can't. The brightness and resolution remain completely consistent: 400cd/m ², 800 × 480. 

Q4: Does the backlight driver need to be modified?

No need. The backlight interface (4-pin terminal, 12V) has the same specifications and can directly use the original backlight driver circuit. 

Q5: Do software drivers need to be re debugged?

No need. Using the same LVDS single channel 8-bit signal format and original driver code. 

Q6: Has there been any change in the working temperature range?

bring into correspondence with. The working temperature range is also -30 ℃~85 ℃. 

Q7: What is the supply situation of this model?

G070VW01.012 is currently in mass production and has stable supply from authorized agents of AU.
