What causes ghost-touch on some smart phones with touch screens?
It depends on when it happens. If it only happens when you’re charging, it’s usually the result of using a poor-quality or damaged charger with too much ripple on the output. Try the charger and cable that came with the phone.If it happens when on batteries, it could be a dirty screen, or faulty digitizer.
What is the difference between OLED and AMOLED? What are its advantages?
OLED (organic light-emitting diode) DisplayOLED display contains a LED, which further comprises an organic material that emits light when current is suffered. As said earlier, OLED's exhibit deeper and darker blacks than the usual LED's. Same as the case with LCD displays, the OLED panels are also classified into two types- PMOLED and AMOLED. Many of us have mostly heard about the AMOLED displays, but most of us haven't heard about PMOLED displays.AMOLED (Active-matrix organic light-emitting diode) DisplayThe newest sensation within the display arena, AMOLED panels springs from the OLED displays itself. It uses identical mechanism as the PMOLED displays but comes with support for larger display sizes. As an example, the PMOLED panels can only support display sizes up to 3-inch, whereas the AMOLED panels don't have any restriction regarding display size. AMOLED displays can be used to any display size and they produce faster refresh rate as well along with dark and inky blacks.Advantages of OLED DisplayThe plastic, organic layers of an OLED are thinner, lighter and more flexibleBecause the light-emitting layers of an OLED are lighter, the substrate of an OLED can be flexible instead of rigid.OLEDs are brighter than LEDs.OLEDs do not require backlighting like LCDsOLEDs are easier to produce and can be made to larger sizes.OLEDs have large fields of view, about 170 degrees.Advantages of AMOLED DisplayIt can be used to any display size andThey produce faster refresh rate as well along with dark and inky blacks.AMOLED ones provide exact color contrasts.As display technology demands shift from traditional AMOLED displays, is it time to start incorporating AMOLEDs into industrial applications?
