Description

MX-B7NR40-TWS63 is a distinctive 7-inch RGB 40 PIN LCD Screen, featuring an 800x480 resolution. Unlike the standard 50 pin interface commonly seen on 7 inch LCD displays, this TFT LCD employs a 40 pin interface. As a TN, Normally White, Transmissive type LCD Screen, it delivers exceptional brightness of up to 600 cd/m2, supported by a contrast ratio of 500:1. It provides a viewing angle of 70/75/75/75 (Typ.) (CR≥10), with the best view observed at the 6 o‘clock direction. With its versatility, the 7-inch screen is perfectly suited for a range of uses, including HMI, industrial environments, medical equipment, and smart home control panels.

Electrical Absolute Maximum Ratings (Vss=0V, Ta=25℃)

Item	Symbol	Min.	Max.	Unit	Note
Power Supply Voltage	V_CC	-0.3	3.6	V	1, 2
Logic Signal Input / Output Voltage	V_IOVCC	-0.3	V_CC+0.5	V
Power Supply Voltage for LCD	Vop	0	2.8	V
Current of LED	ILED	0	60	mA

Notes:

1. If the module is above these absolute maximum ratings. It may become permanently damaged. Using the module within the following electrical characteristic conditions are also exceeded, the module will malfunction and cause poor reliability.

2. V_CC >V_SS must be maintained.

3. Please be sure users are grounded when handing LCD Module.

Environmental Absolute Maximum Ratings

Item	Storage		Operating		Note
Item	MIN.	MAX.	MIN.	MAX.	Note
Ambient Temperature	-30℃	80℃	-20℃	70℃	1, 2
Humidity	-	-	-	-	3

1. The response time will become lower when operated at low temperature.

2. Background color changes slightly depending on ambient temperature. The phenomenon is reversible.

3. Ta<=40℃: 85%RH MAX.

Ta>=40℃: Absolute humidity must be lower than the humidity of 85%RH at 40℃.
