Redmi launched its Redmi K30 Series with a small compromise with a diggin display, which means a yellowing near the punch-hole digging screen. Before going ahead, let’s know the characteristics of the LCD used in the Redmi K30.
The display panel is an LCD with liquid crystal layers of 3μm, which means it is quite a thing and a fragile material. Meanwhile, there are two parallel layers of glass called CF Colour Film and TFT Substrate. As the display is very large, it is ideal to use two glasses that are not yellow.
However, if the parallel plating of two layers of glass has been broken, the screen will show yellow due to the uniformity in the liquid crystal changes. Not to mention, there were two major advantages to the new generation of the Redmi K30 digging screen, as explained by Lu Weibing.
First things first, upgraded “thickened glass” was used to increase thickness by 14% and provide more structural strength. Also, it has a large number of support pillars to increase the density of support columns. Which are added around the hole, and the density of the support pillar means a higher level of stability by using two glass structures around the punch hole.
Additionally, Redmi K30 uses the latest processes for low-shrink polarizers and upgraded dispensing technology. Which allows the display and screen structure to achieve long-term stability. Moreover, the Redmi K30 uses the industry’s smallest LCD aperture with a 4.38mm diameter punch-hole display technology called “Three Reductions.”
The main advantage is that the MINI Punch-Hole Camera Module for Selfie Camera is used to optimize the dispensing process and improve the dispensing ability for punch-hole width to ensure strength. The bezel-less experience by reducing a bezel around the hole effectively prevents light leakage.
