4-inch LCD square screen 480*480 resolution MIPI/RGB interface 86 switch panel player display screen

3.95-inch 'small square screen' out of the circle! TXW395041B0 lifts the 86 switch panel directly to the flagship level

Why is it a 'square screen' again?
Those who work in smart homes know that circular UI is the most pleasing in a 1:1 ratio - without black borders, no cropping, and icons that don't deform no matter how big they are. So we made 3.95 inches into a 480 × 480 square, stretched the visible area to 71.86 × 70.18 mm, and stuffed it into the 86 box without leaving any gaps.

02 | Not picking angles is true intelligence
IPS Full View, officially known as ALL O'CLOCK, means that when you stand, squat, or look diagonally, the colors will not "flip over". Installed on the living room wall, the whole family can see the temperature, humidity, music lyrics, and even doorbell screen at a glance from any angle.

03 | Brightness of 300 nits, stable even during the day
300 nits may not sound exaggerated, but when combined with a frosted glass cover, it is still clear under 800 lux illumination in the living room during the day. Key low power consumption: 8 LED side in backlight, can be lit up with 5 V/150 mA on the entire board, does not heat hands in summer, and does not flash screen in winter.

04 | Dual interface form, zero threshold for development
3-SPI: Tune registers, flash libraries, and run with just one DuPont wire. 18 bit RGB: Running a 60 Hz video stream without dropping frames.
Extra 2 lanes of MIPI are reserved, and the new board to be released next week can be directly plugged in and used.
40 Pin 0.5 mm FPC, Positive and negative insertion does not waste the board, saving one SMT for sampling.

05 | Wake up in seconds even at -20 ℃
Has the heating system in Northeast China stopped? Outdoor fresh air fan? Don't panic, the working temperature is -20 ℃~+70 ℃, and it has been tested to be -18 ℃ in Harbin. The indoor wall will hang overnight, and the next day it will light up with just a touch of your finger. If the storage temperature drops to -30 ℃, logistics will not explode during winter.

06 | Incell touch, one less layer of glass
The touch layer is directly made inside the LCD, and the whole machine is thinner by 0.4 mm, leaving more space for the power board in the 86 box. Wet hands, oily hands, and wearing household gloves can all be operated, so Mom no longer needs to find a cloth to wipe the screen in the kitchen.
