[Learn Display] 34. Display Driver IC

There’re several steps to show an image on the screen. Display Driver IC is an indispensable semiconductor chip to operate each sub-pixels. DDI accepts a signal of an image from the CPU of the device and generates and controls the output signals. To put it simply, Display Driver IC commands the order to each sub-pixel on the panel how to operate. Display Driver IC is composed of Gate IC, Source IC, and etc. When a certain amount of electricity is applied to TFT depending on the voltage differences between Gate IC and Source IC, TFT works as a switch to turn on/off each sub-pixels. The color of the display varies upon the on/off operation of each sub-pixels and the display generates an expected image on the screen eventually.

[Learn Display] 33. Touch Screen Panel

Touch Screen Panel (TSP) refers to a device that identifies coordinates of the exact place when pressing or touching the display screen. Smartphones that we commonly use features touch screen panel, so we can pilot our smartphones by touching the screen without separate external buttons. The type of touch screen panels varies depending on how they work, such as capacitive touch, resistive touch, infrared ray touch, and acoustic wave touch. Early smartphones adopted a resistive which operates by the pressure applied. This method recognizes users’ touch when upper and lower substrates are in contact due to external pressure. As a result, this method comes with the disadvantage of a low touch recognition rate since it requires pressure hard enough to have films contact. Meanwhile, most of the latest smartphones use capacitive-type touch screen panels.  This method detects the change in capacitance of the electric conductor, such as a human hand, as soon as it touches the touch screen. Likewise, the capacitive type has good touch sensitivity and befits small and medium-sized models, so most mobile devices adopt it. Touch screen…

[Learn Display] 32. Window

‘Display Cover Window’, also known as a window, is a component that safeguards a display panel from the outer impact. The window should be transparent since the image screen generated by the display need to reach our vision even after covering up the screen for protection. These functions and characteristics resemble a window in a wall, so the cover window is also called ‘window’ in short.  The introduction of a screen touch function on smartphones removed most of the physical input devices such as keypads, which increased the size of a display. Windows also evolved in line with this trend, so existing plastic windows were replaced with glass material resistant to scratches even after a series of touches. Smartphone design innovation continued with the advance of glass processing technology. Glass windows evolved from flat glass plates (2D) to 2.5D windows featuring gently curved edges or 3D windows with curved edges like the Galaxy Edge series to create improved designs.     The very first foldable displays, unveiled in 2019, use not glass but flexible CPI (Colorless Polyimide) material for cover windows.…
