2.8 inch spi tft lcd ili9341 quotation

The YT028l001 is a 2.8-inch wide LCD cell with thin film transistors as active elements and contains 240(H) X 320(V) pixels. Each pixel is divided into red, green and blue dot, which are arranged in vertical stripe. The cell is normally white mode, and can be applied to the transmission type display. Backlight unit (BLU) and circuit board for the cell are not built in.

Meanwhile, we do necessary Aging test and Reliability tests to our TFT Display modules, eg. Store and Operate in High and Low Temperature & High Humidity Environment, ESD and anti-interference test , Drop(with package) and Vibration Test.

A:Yes, sample order is always welcome for new projects or replacement of running projects. We have stock of many standard models of TFT LCD modules and Touch screens from 0.96inch to 13.3inch , which means delivery is able to be made the same day as order.

--In summary, based on our years of big output, we have been keeping good relationship with LCD panel, IC and other material suppliers, we had a steady supply even when there was heavy shortage of materials.

The 2.8inch lcd module uses a 4-wire SPI communication method with a driver IC of ILI9341 and a resolution of 240x320 and a touch function(optional).The module includes an lcd display,backlight control circuitry,and touch screen control circuitry.

Reaper , over ten years manufacturer and exporter of various LCD display including mono LCD, TFT display, OLED display, touch panel and customized LCD solution.With the advantages of high contrast,fast response time, wide viewable angle and low power consumption, Reaper"s products are widely used in Industrial Equipment, Medical devices,Home Intelligent Devices, Digital comsumers, Video Game Devices,Instruments etc.

So after half a days soldering, I fire up the board and excellent, the ILI9341 is running at a clock speed of 100mhz (not scoped), lightning fast! Dropped the speed to a more reasonable 20mhz and left overnight for a board test (i always do this, as i have lipos connected etc and like to see if there are any heat issues etc after a 24h run). Found no issues the next morning, graphics test still running so powered off the device.

Powered back up after my return from work @20mhz and the graphics test worked fine. Enabled my SD circuitry (solder jumpers), reran the test and both the ILI9341 and SD were both running sweet.

No changes made, powered up on the third day, and nothing but a white screen on the ILI9341? So i say, must have blew the t4 some how. Hot air removed the t4, on goes the new one and again a few runs later and i get a white screen again? Checked all my pin assignments, voltages and they are all good.

I came to the conclusion that as I was forcing the T4 to be powered of of 3v3 as per (https://forum.pjrc.com/threads/64468...V-power-supply) this was somehow messing with the SPI communication. I canned the T4 and designed and built a T4-SAMD51 clone.

I picked up the project again today and de-soldered my SAMD51 T4 clone pcb as I need speed! The T4 would have been perfect, so tried a few code changes, got the screen running in the setup function (static text etc), but as soon as it enters the loop(), you guessed it....white screen. Its as if the t4 is too fast on spi or something, but I have changed the clock speeds down to 5mhz and yield the same results...

To confirm, I had the T4 intermittently working on both the adafruit ili9341 library and the optimised ili9341_t3. I"ve been through 3 T4s and I have 5 different ILI934 displays. (all give the same results, pull ups, no pullups, removed sd circuitry, ran the T4 at 5v I"ve tried it all!)
