A display is created using “smart pixels.” A smart pixel is a pixel of a display that integrates the pixel pipeline as part of the pixel, rather than using separate integrated circuits. A smart pixel may be based on an integrated stack that includes light emitting elements, an external data contact for receiving digital data for that pixel, and also the pixel pipeline from the digital data to the light emitting elements.

A display device can include a display panel having a plurality of pixels disposed on a substrate, and a power supplier configured to supply a driving voltage to the display panel. The power supplier can include a first converter configured to receive an input voltage supplied from an external system and convert the input voltage into a boost voltage, a second converter configured to convert the boost voltage into the driving voltage, a first feedback unit configured to output a first pulse width modulation (PWM) signal to the first converter so that the boost voltage is proportional to a first reference voltage, and a second feedback unit configured to output a second PWM signal to the second converter so that the driving voltage is proportional to a second reference voltage.

A method for optimizing a display image based on display content is provided. The method is applicable to a display control chip, and includes following operations: receiving a video signal configured to transmit an image of a frame; with respect to multiple different sub-areas in an area of the image, calculating a pixel number distribution of each sub-area along multiple characteristic values; determining, according to the pixel number distribution, whether the sub-area comprises a corresponding first target pattern of multiple first target patterns; if the multiple sub-areas comprise the multiple first target patterns, respectively, performing a first preset image processing to the image to generate a processed image; if the multiple sub-areas are free from comprising the multiple first target patterns, respectively, omitting the first preset image processing to the image; and generating a display signal according to the processed image or the image.

A method for mitigating interference across analog signal lines includes receiving a digital data stream including a plurality of discrete signal patterns configured to drive a plurality of different analog signal lines. An edge buffer for each analog signal line is populated with edge data representing pulse edges of upcoming signal patterns set to drive the analog signal line. A target buffer for a target signal line is populated with target data representing a target signal pattern. Based at least in part on determining that edge buffers corresponding to one or more potentially interfering analog signal lines include edge data corresponding to post-target pulse edges, one or more potentially interfering signal patterns are identified. A selected set of the potentially interfering signal patterns are used to modify the target signal pattern to perform preemptive interference mitigation.
