3.5 inch tft lcd screen module ultra hd 320x480 factory

Sunnyis a professional high-tech enterprise,which specializes in LCDslicing and filling,the researching,designing,manufacturing and selling of LCD(Liquid Crystal Display),LCM(LCD Modules). it is located in NanYu Industrial Area, Longhua District., Shenzhen,only a 30-minutes drive from Baoan International Airport.

ER-TFTM035-6 is 320x480 dots 3.5" color tft lcd module display with ILI9488 controller and breakout board,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO,ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.

It supports 8080 8-bit /9-bit/16-bit /18-bit parallel ,3-wire,4-wire serial spi interface.Built-in microSD card slot, optional 3.5" 4-wire resistive touch panel with controller XPT2046 and capacitive touch panel with controller FT6236, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover . It"s optional for font chip, flash chip and microsd card. We offer two types connection,one is pin header and the another is ZIF connector with flat cable mounting on board by default and suggested. Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.5"TFT Touch Shield with Libraries, EXxamples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

Are you a factory or trading company9 A1: We are a OEM/ODM TFT LCD Display manufactuer factory and factory based on Bao"an Shenzhen. Q2 . What is the MOQ9 A2: There are no MOQ requirements,We can cooperate step by step. Q3 . What"s the lead time of the products9 A4: Sample in stock, 2-4 weeks for mass production. Q5 .

I purchased 2 screens and both have similar issues with colors. They are displaying content, but problem is that colors are not correct most of the time. It looks like always one of the RGB component is missing or not intensive enough, and it is totally random. Every time I turn on LCD it shows different spectrum and stays in that spectrum until next power cycle. I"m sure that it is not problem with libraries or my code because in rare occasions these panels shows correct colors and stays in correct color spectrum until next power off/on. I have others LCD screens which physically look like these (both 3.5" and 3.2") and these work correct all the time. I take photos of 4 consecutive powering of the same display. The most prominent difference can be seen on bar graph on the left (it should be pale yellow in original and here colors are from pale grey to yellow-greenish to purple-bluish). I cannot blame seller for this problem because displays came in OEM packaging and undamaged.

Ok, I played couple of days with these screens trying to achieve good and consistent color spectrum. I think that I finally made it to work. It seems that these displays came from factory with somehow wrong default settings for gamma and refresh rate. If you experience similar issues try to change data values in following commands: C0h, C1h, E0h, E1h, E2h, E3h and 36h. For example, I changed values for C0h to 0x1F for first register (sets VREG1OUT for positive gamma to 5.500V) and 0x01 for second (sets VREG2OUT for negative gamma to 3.625V). Please look at new picture below. It is much better than before. According to these new findings I will rate this product with 4 stars now...
