Apple's new patent can solve a variety of shortcomings OLED display

Although Apple does not currently have a device equipped with a OLED display screen, but the company is still trying to improve the OLED technology solutions, such as the use of the diode for a long time due to the change in the color of the OLED. The patent contains a number of advanced technologies to detect and compensate for fluctuations in light. Compared with most of today's consumer electronic devices used on the LCD LCD panel, OLED has many advantages.

The United States Patent and Trademark Office recently passed an apple application to be able to compensate for environmental light fluctuations and diode aging OLED display patent.

This paper describes the use of embedded sensors to dynamically adjust the output of certain areas of the screen to compensate for ambient light fluctuations or the use of light emitting diodes.

Although Apple does not currently have a device equipped with a OLED display screen, but the company is still trying to improve the OLED technology solutions, such as the use of the diode for a long time due to the change in the color of the OLED.

The patent contains a number of advanced technologies to detect and compensate for fluctuations in light. Compared with most of today's consumer electronic devices used on the LCD LCD panel, OLED has many advantages.

Including OLED can send their own colored light source, so that the display is thinner and lighter, visual angle will not be reduced. OLED can be configured on rigid or flexible panels.

Of course, there are many shortcomings of OLED, for example, compared with the LCD display, OLED decay quickly, which means that some LEDs will be different from other brightness, affect the overall light. This phenomenon is common blur.

In Apple's patents, describes a photoelectric sensor placed above, below, or parallel to the OLED array to detect and compensate for possible changes. Using the data from the photodiode, the controller can detect changes in light emission under different conditions. For example, ambient light information can be obtained by photodiode.

For example, if the display is too dark, the controller can be adjusted according to the situation. Because the sensor is part of the display, rather than adjacent layout, coupled with the use of iPhone and iPad ambient light sensor, the data will be more accurate.

It is also mentioned in the patent that the photodiode can also collect the information of the independent OLED or the pixel group, and adjust the luminous degree according to the preset signal or other OLED configuration. If the OLED is detected because it is too long to produce color and brightness through the surrounding diode, the controller compensates for a particular component.
