3.97inch TFT LCD Display Module With 480×800 Resolution ST7701S IC MIPI Interface
Description
T-397BS2503 is a color active-matrix thin-film transistor (TFT) liquid crystal display (LCD) that adopts amorphous silicon TFT as the switching device. It mainly consists of LCD panel, flexible circuit board, backlight element and driving IC. There is an active display area with a diagonal size of 3.97 inches, capable of displaying a color screen of 480*800 pixels. This 480x480 TFT liquid module adopts TN display mode, with the best viewing angle being ALL, and the normal operating temperature is -20~+70. The service life is up to 20,000 H. Besides, T-397BS2503 is a customizable color LCD module. It can be customized according to customer requirements, such as interface definition, flexible circuit board design, brightness adjustment, screen display processing (anti-glare), etc.
Of course, we can also design an exclusive LCD display solution according to your wishes. You can consult through online customer service or send us an email to obtain relevant information. We look forward to your contact as soon as possible.

Measurement system
1.LCM Viewing Angle
Viewing angle is the angle at which the contrast ratio is greater than 10.The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface.
2.Response time
Response time is the time required for the display to transition from white to black (Rising time, Tr) and from black to white (Falling time, Tf) for additional information.
3.Contrast Ratio (CR)
Contrast Ratio (CR) is defined mathematically as:
Surface Luminance with all white pixels
Contrast Ratio=
Surface Luminance with all black pixels
Surface luminance is the center point across the LCD surface 500mm from the surface with all pixels displaying white.
