Current status of touchscreen display products
CRT displays to LCD displays
The display monitors we use in our everyday lives. PCs began to spread and were used in offices in the 1980s. In the beginning, analogue displays using CRTs (cathode ray tubes) were common and many were black and white; by the mid-1980s, laptop PCs were widespread, and by the late 1980s, full-colour graphic displays became popular, and with the development of notebook PCs and other lightweight products, LCD displays came into use.
Slim, well-designed display products are common
LCD monitors, which were still expensive, were generally designed with ostentatious bezels and enclosures, but nowadays slimmer, more design-oriented displays are becoming mainstream. The trend is for bezels to have extremely narrow frames and thin, lightweight enclosures, and this has evolved in tandem with technological developments. This is largely due to, amongst other things, the fact that colour reproduction, contrast, viewing angles and the display of fast-moving images, photos and videos have become commonplace in our daily lives.
Widespread use of LCDs with touch screens
An increasing number of today’s touch-enabled displays on smartphones and tablet products are thin and compact, with virtually no bezel frame and larger screens that can still be used in the palm of the hand. Many of these slim, well-designed display products around us are intended for consumer applications. Consumer products do not face the challenging requirements of industrial applications, such as long-term supply, environmental resistance, reliability, and support. For industrial applications, it is necessary to select monitor and touch display products that are designed to operate for long periods of time and under harsh environments.
