Certain embodiments are directed to techniques (e.g., a method, an apparatus, and non-transitory computer readable medium storing code or instructions executable by one or more processors) for mitigating the flicker on the displays at low driving frequencies due to drops of the voltage holding ratio of the materials for the display. The techniques to compensate for flicker in a liquid crystal display can include generating a dynamic waveform for the backlight of the display. The dynamic waveform can be synchronized with the driving rate of the liquid crystal display such that the luminosity of the backlight increases during periods when the voltage-holding ratio drops in the materials of the display. In this way, a liquid crystal material can be utilized in a display to generate reduced power consumption with liquid crystal rate minimizing the flicker in response to the drops of the voltage-holding ratio.

A liquid crystal display device includes a first liquid crystal display panel that displays a color image, a second liquid crystal display panel that displays a monochrome image, and a display controller that controls the display of the first liquid crystal display panel and the display of the second liquid crystal display panel. The display controller switches the display of the second liquid crystal display panel between a monochrome display that displays a monochrome image and an all-white display. In a state in which the display of the second liquid crystal display panel is the monochrome display, when a response time between predetermined gradations is greater than or equal to a predetermined first response time, the display controller switches the display of the second liquid crystal display panel from the monochrome display to the all-white display.

A light emitting apparatus includes a light emitting element, a temperature measurement device, a driving control unit, a calculation unit configured to calculate a correction value of a driving control parameter based on a measured temperature; and a change unit configured to change a coefficient of a function based on the measured temperature. The calculation unit calculates the correction value with respect to the measured temperature based on a function obtained by expressing a first function, which expresses a relationship between the measured temperature and the correction value, by a combined function of a plurality of third functions each generated by changing a coefficient of a second function, and the change unit changes, based on the measured temperature, the coefficient of the second function to generate the plurality of third functions.

A display apparatus capable of correcting an image quality change caused by long-term use is provided. The display apparatus includes: a display panel; a communicator configured to communicate with a service apparatus; and a controller configured to control the communicator to transmit operation information including a total operating time of the display apparatus and an operating temperature of the display apparatus, to the service apparatus; receive an image parameter from the service apparatus through the communicator, and based on the received image parameter data; process image data; and transmit the processed image to the display panel. The image parameter may include at least one of a brightness level, a contrast, a sharpness level, and a color density of the display panel.

A temperature control method is provided. In the method, a terminal determines a current temperature of the terminal and determines, based on a preset corresponding relationship between a screen display frame rate and a temperature interval, a target temperature interval of the current temperature of the terminal in the preset corresponding relationship. The terminal may determine a target screen display frame rate corresponding to the target temperature interval. And the terminal may adjust a current screen display frame rate of the terminal to the target screen display frame rate, to control the temperature of the terminal to be within a preset temperature range.

Devices and methods for dynamic power configuration (e.g., reduction) for thermal management (e.g., mitigation) in a wearable electronic device such as an eyewear device. The wearable electronic device monitors its temperature and, responsive to the temperature, configures the services is provides to operate in different modes for thermal mitigation (e.g., to prevent overheating). For example, based on temperature, the wearable electronic device adjusts sensors (e.g., turns cameras on or off, changes the sampling rate, or a combination thereof) and adjusts display components (e.g., adjusted rate at which a graphical processing unit generates images and a visual display is updated). This enables the wearable electronic device to consume less power when temperatures are too high in order to provide thermal mitigation.

The present disclosure describes a method and apparatus that can be used to adjust for distorted ambient light readings caused by the ambient light sensor being located behind the display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into independent sources (e.g., red, green, and blue display components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, a more accurate ambient light measurement can be obtained in some instances. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.
