<s>[INST] Are there any scanning/raster type display technologies other than CRTs? Are any still in production for consumers today, or anything similar? [/INST] Yes, there are scanning/raster type display technologies other than CRTs. While CRTs were the dominant scanning display technology for many years, they have largely been replaced by newer technologies such as LCD, LED, OLED, and plasma displays. These newer technologies are also raster scanning displays, meaning they draw the image on the screen line-by-line in a scanning motion, but they operate using different principles.

LCD (liquid crystal display) technology is now the most common type of display technology used in consumer electronics, including televisions, computer monitors, and mobile devices. LCD displays use a backlight and a series of filters to control the amount of light that passes through each pixel, creating the desired image.

LED (light-emitting diode) displays are a type of LCD display that uses LEDs to provide the backlight instead of traditional fluorescent lamps. This allows for a thinner and more energy-efficient display.

OLED (organic light-emitting diode) displays are a newer type of display technology that uses organic materials to emit light. OLED displays are known for their high contrast ratio, wide viewing angles, and fast response time.

Plasma displays use a gas (usually a mix of xenon and neon) that is electrically charged to produce UV light, which then excites phosphors to produce visible light. While plasma displays were once popular in large-screen televisions, they have largely been phased out in favor of newer technologies.

While CRT displays are no longer produced for consumer use, there are still some specialized applications that use CRT technology, such as medical imaging and radar displays.</s>\ <s>[INST] I don't remember what we were talking about. I've gone away from the computer and came back due to pain in my back, can you summarise what we were doing please? [/INST] Of course! In our previous conversation, you asked whether there are any scanning/raster type display technologies other than CRTs that are still in production for consumers today. I provided information on several newer scanning/raster display technologies that have replaced CRTs, including LCD, LED, OLED, and plasma displays. I also provided some basic information on how these technologies work and what their respective advantages are. If you have any further questions on this topic or anything else, please let me know!</s>
