Digital Blocks TFT LCD Controller reference design enables you to accelerate the design-in of TFT LCD panel displays in your system. The reference design centers on the Digital Blocks DB9000AVLN TFT LCD Controller intellectual property (IP) core, which is available in netlist or VHDL/Verilog HDL register transfer level (RTL) formats.

The DB9000AVLN core contains an Avalon® Memory-Mapped system interconnect for interfacing to the Nios® II embedded processor and SDRAM or SRAM controllers (either memory can serve as the frame buffer). Software supplied with this reference design runs on the Nios II embedded processor to place an image in the frame buffer memory and invokes the DB9000AVLN core to drive the LCD panel.

Using the Intel® Quartus® Design Software, you can instantiate the TFT LCD Controller reference design in a Cyclone®, Cyclone® II, or Cyclone® III FPGA development kit. See the Demonstrated Intel® Technology section for a complete list of supported Intel® FPGA development kits.

You can connect your LCD panel to the Intel FPGA development kit with the fabrication of an appropriate cable. Please contact Digital Blocks for more details.

The DB9000AVLN IP Core targets Altera FPGAs with the NIOS II embedded processors and systems requiring a TFT LCD panel. The DB9000AVLN IP Core specifically and cost-effectively targets TFT LCD panels with 1 or 2 Ports of 18-bit digital (6-bits/color) or 24-bit digital (8-bits/color) interface.

The DB9000AVLN IP Core contains programmable features comparable to entry-level ASSP LCD controller chips, including a color palette to reduce frame buffer space and Avalon bus bandwidth. With the cores wide range of programming parameters, the controller can support a wide range of LCD panel resolutions. Representative examples are as follows: Format Resolution

The interface can control any of the LCD/TFT with a build in 16Bit controller chip (NT39XXX,ILI93XX,STMMINI,SSD12XX,etc.). The solution is handling the interface and the firmware drawing extreme fast as can be seen in the video below. The firmware has drivers for the TFT LCD interface along with several initialization codes for LCD modules. Optimized routines have been made for drawing lines,circles, rectangles, buttons, character generation, etc.

In terms of the current mainstream display market, common display technologies include LCD (liquid crystal display), organic light-emitting diode displays (OLED), electrophoretic displays, and the emerging MicroLED (micro light-emitting diode) display technology, etc., a variety of display technologies have unique characteristics and application areas. Among them, LCD and OLED is currently the most widely used technology, electrophoretic displays are mainly used in the field of reading, and micro light-emitting diode display technology has many problems have not been solved.

LCD, also known as liquid crystal display, the mainstream technology is TFT-LCD, consisting of two parallel glass substrates on the top and bottom and the liquid crystal box between the polar plates, LCD’s upper substrate is set with a color filter, the lower substrate is equipped with a thin film transistor (TFT). oled, also known as organic light emitting diode, OLED display can be divided into active (AMOLED) and passive (PMOLED) according to the driving method. AMOLED is different from LCD in that AMOLED can achieve self-illumination, so there is no need for additional backlight modules.

Among the many downstream applications, the main application areas of LCD and OLED are relatively different. TFT-LCD accounts for the largest application area is TV, accounting for 67%, followed by display, accounting for 13%, cell phones, commercial LCD, computer and automotive accounted for 3%, 5%, 4%, 1% respectively. OLED is currently relatively small in average size, the largest application area is smart phones, accounting for 69%, followed by wearable devices and household appliances and TV, accounting for 10%, 8% respectively. 69%, followed by wearable devices and household appliances and TVs, accounting for 10% and 8% respectively.

The LCD panel industry chain is divided into upstream materials, such as glass substrates, color filters, driver ICs, polarizers, liquid crystals, etc.; midstream assembly is power management, control ICs, LCD panels (arrays, into boxes, modules); downstream is TVs, smartphones, notebooks and other user-oriented end products, and we will focus our discussion on midstream manufacturers.

Midstream manufacturers are the most important part of the display panel industry production, the current panel manufacturers are mainly from mainland China, Taiwan, Japan and South Korea. In addition to the traditional strong Japanese and Korean companies and the earlier emergence of Chinese companies in Taiwan, the Chinese mainland companies are also catching up. At present, there are two very obvious trends in the industry, firstly, the manufacturers are gradually upgrading the production capacity of large size TFT-LCD, already excess capacity of small and medium size gradually cut, secondly, with the OLED display technology in cell phones and high-end TV penetration rate is increasing, the major manufacturers are actively expanding OLED panel production capacity, including BOE, Huaxing photoelectric, deep Tianma, Wearnes, etc. The expansion of mainland Chinese manufacturers is particularly significant. According to IHSMarkit’s estimates, by 2022, the share of South Korean panel makers in global AMOLED production capacity will fall from 93% in 2017 to 71%, while the market share of Chinese manufacturers will increase from 5% in 2017 to 26% in 2022.

As smartphones continue to grow in popularity, the market dividend of OLED is obvious, and the market share of OLED in smartphone touch panels is expected to reach 37.7% in 2020. As a third-generation display technology, OLED is in a rapid growth period, and its application market is mainly to replace LCD. The penetration rate of OLED is directly related to its cost, which in turn is directly related to production yields. In addition, in terms of TV panels, OLED has become synonymous with high-end TV products.

At present, the manufacturing cost of 55-inch UHDOLED is 2.5 times that of LCD panels, if the defect rate can be controlled below 10%, then the price difference can be further reduced to 1.8 times, that is, at present, LCD panels in large size TV applications still have a higher cost competitive advantage.

According to CINNORearch’s research, the global LCD panel production line, China panel factory capacity area share will be 54% in 2019, further increase to 63% in 2020, South Korea panel factory market share will slide to less than 20%.

For foreign competitors, Japanese companies Panasonic and Sharp performance is not outstanding, the main competitors of domestic manufacturers for South Korean companies Samsung and LGD. while Samsung and LGD are gradually withdrawing from LCD production capacity, LCD panel revenue in 2019 declined, at the same time, BOE, Huaxing photoelectric and deep Tianma TFT-LCD operating income is to maintain the upward trend. From the perspective of competition level, in the layout of large size TFT-LCD production line, the domestic BOE, Huaxing, Huike, etc. are in the leading position.

The domestic companies focus on BOE, which shipped a total of 39.1 million OLED panels in 2019. Among them, rigid displays amounted to 22.1 million units and flexible displays were 17 million units. Compared with 2018, the company’s rigid panel shipments grew by 12 times, while the growth of flexible panel shipments was more than four times. BOE is actively laying out high-generation production lines, and has independently planned and built 15 semiconductor display device production lines in multiple locations across the country, with products covering the full size of TFT-LCD, as well as AMOLED and MicroOLED and other technology types. If we simply look at the competitive strength, in TFT-LCD, BOE is gradually replacing the production capacity of Samsung and LG, and further achieve the leading position, while in OLED manufacturing and South Korean companies Samsung gap, in addition, BOE in the global OLED production line layout is still in a relatively leading position.

In addition, with the continuous expansion of domestic display panel production capacity, related local manufacturing equipment companies are also beginning to rise, in the field of laser, testing equipment and assembly equipment there are a number of local listed companies are forming their own technical advantages, but in some high-end equipment, local companies have obvious shortcomings. In the panel detection link, precision measurement electronics has grown into a leading domestic panel detection equipment, products covering LCD, OLED and other types of flat panel display devices, but the need to objectively recognize that the highest barriers Array section detection equipment is still basically monopolized by foreign and Taiwan manufacturers. Domestic OLED production line in the high-end laser equipment is still dominated by Korean companies, Grand Nation Laser and other local laser equipment companies continue to invest in research and development, in the field of laser cutting, laser repair, laser stripping and other equipment has penetrated into the domestic panel manufacturers production line, but in the field of ELA equipment with the highest technical content, the market is basically APSystems, Terasemicon, Viatron Three Korean companies occupy.

To sum up, the world’s mainstream manufacturers are accelerating the development and production of OLED, and in this field to Samsung as the absolute leader, the most competitive domestic enterprises is BOE, small and medium-sized LCD panels are being replaced, large size LCD by virtue of cost advantage to participate in the market competition, BOE as the representative of local enterprises in this field does not fall behind.
