imx6 lcd panel pricelist

The iMX6 Rex UltraPlus development system based on i.MX6 ARM CortexTM-A9 core family CPU clocked up to 1.2GHz has been designed to significantly reduce one"s own application development time as well as the final device time to market by allowing:

All of the standard iMX6 Rex Module configurations are equipped with one 60-pin High Speed Ground Plane Socket on position J1 that provides access to all of the basic, must-have peripherals.

The UltraPlus, Ultraand Pro configuration COMs are equipped also with the second connector on position J2 that contains additional, high speed interfaces. For more details about the peripherals location on J1 and J2 high speed ground plane sockets see the iMX6 Rex Module block diagram.

The iMX6 Rex Pro development system based on i.MX6 ARM CortexTM-A9 core family CPU clocked up to 1.2GHz has been designed to significantly reduce one"s own application development time as well as the final device time to market by allowing:

This application note describes the i.MX6 CPU graphical system and the steps to define a new custom TFT (Thin Film Transistor) display panel in Digi Embedded Yocto and discusses the most standard panels available. Some panels may need special consideration.

An LCD panel is a matrix of pixels that are divided into rows and columns. These pixels are individually painted according to different signals and timing parameters, and you can control each pixel"s color individually. The panel is continuously refreshed, typically at around 60 Hz, from the contents of the frame buffer memory. Each memory location on the frame buffer corresponds to a pixel on the LCD panel.

A 1024 x 600 resolution display requires 614400 memory locations, with each location having a number of possible colors. The number of bits needed to describe the available colors is called bits per pixel (bpp). For example, 16 bpp can describe 65536 colors and 24 bits can describe 16777216 colors (known as true color). A panel with 614400 24-bit locations requires a 1800 KB frame buffer.

Every manufacturer provides display timings in a slightly different way and some provide more detail than others. Most LCD panels work with a range of timing parameters.

LCD displays must be created as nodes in the device tree with a display-timings subnode. Display timings binding documentation at Documentation/devicetree/bindings/video/display-timing.txt explains the required timing properties to describe an LCD.lcdname {

hfront-porch is the horizontal front porch, the number of clock pulses (pixels) between the last valid pixel data in the line and the next HSYNC pulse. According to the LCD data format, this value is zero.

vfront-porch is the vertical front porch, the number of lines (HSYNC pulses) between the last valid line of the frame and the next VSYNC pulse. According to the LCD data format, this value is zero.

NoteThe recommended timings from the LCD datasheet often do not work perfectly, as each platform introduces noise and delays that affect the display"s signals and timings.

This color chart displays a white one-pixel frame at the edges of the LCD (which allows you to verify correct position and width/height), and gradients of red, green, blue, and white (which allow you to verify correct color depth and format).

It may seem odd in the face of stalled economies and stalled AV projects, but the costs of LCD display products are on the rise, according to a report from Digital Supply Chain Consulting, or DSCC.

Demand for LCD products remains strong , says DSCC, at the same time as shortages are deepening for glass substrates and driver integrated circuits. Announcements by the Korean panel makers that they will maintain production of LCDs and delay their planned shutdown of LCD lines has not prevented prices from continuing to rise.

I assume, but absolutely don’t know for sure, that panel pricing that affects the much larger consumer market must have a similar impact on commercial displays, or what researchers seem to term public information displays.

Panel prices increased more than 20% for selected TV sizes in Q3 2020 compared to Q2, and by 27% in Q4 2020 compared to Q3, we now expect that average LCD TV panel prices in Q1 2021 will increase by another 12%.

The first chart shows our latest TV panel price update, with prices increasing across the board from a low in May 2020 to an expected peak in May/June of this year. Last month’s update predicted a peak in February/March. However, our forecast for the peak has been increased and pushed out after AGC reported a major accident at a glass plant in Korea and amid continuing problems with driver IC shortages.

Prices increased in Q4 for all sizes of TV panels, with massive percentage increases in sizes from 32” to 55” ranging from 28% to 38%. Prices for 65” and 75” increased at a slower rate, by 19% and 8% respectively, as capacity has continued to increase on those sizes with Gen 10.5 expansions.

Prices for every size of TV panel will increase in Q1 at a slower rate, ranging from 5% for 75” to 16% for 43”, and we now expect that prices will continue to increase in Q2, with the increases ranging from 3% to 6% on a Q/Q basis. We now expect that prices will peak in Q2 and will start to decline in Q3, but the situation remains fluid.

All that said, LCD panels are way less costly, way lighter and slimmer, and generally look way better than the ones being used 10 years ago, so prices is a relative problem.
