Embodiments of the present invention provide a display signal processing method and device, and a self-luminous display, which relate to the display field and can improve the display life of pixels in the self-luminous display, thereby improving the display life of the self-luminous display as a whole. The specific scheme is: obtain the RGB grayscale value (X, Y, Z) of the preset pixel, according to the RGB grayscale value (X, Y, Z), and the preset m grayscale coefficient groups (Ui, Vi , Wi), obtain m groups of RGB display grayscale values ​​(Xi, Yi, Zi), according to the m groups of RGB display grayscale values ​​(Xi, Yi, Zi), output m groups of scanning grayscale values, for all The preset pixels are scanned m times continuously in one display period. The invention is used for the display signal processing of the display.

The invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes a display area arranged on the substrate, and at least one PMOLED is included in the bending area of ​​the display area. Since the PMOLED is not driven by a thin film transistor, it effectively avoids the impact of the electrical change caused by the bending of the thin film transistor. The influence of display performance, further, an organic insulating layer is included between the substrate and the first OLED unit, and the organic insulating layer includes an organic material. Since the organic material has good strain elasticity compared to the inorganic material, The bending resistance of the bending area can be improved. The display lifespan of the display area can be effectively improved by using the manufacturing method of the display substrate provided by the present invention. The display device provided by the present invention comprising the above display substrate includes at least one PMOLED in the bending area of ​​the display area, which can avoid display performance changes caused by bending of thin film transistors.

The invention relates to a preparation method of a stable double-particle system electrophoretic display solution for electronic ink display. Pigment electrophoretic particles which have small particle diameter and good dispersibility can be obtained through recrystallization and surface modification, and the dispersion stability and the surface charge of the particles can be improved by adding charging agents and dispersing agents. The particle diameter of the electrophoretic particles in the invention can reach 30-350nm. Two single-particle electrophoretic display solutions are prepared in proper proportions, and proper stabilizing agents and charging agents are added to obtain the double-particle system electrophoretic display solution, thereby obviously improving the display contrast,shortening the response time (the response time is 0.8-2s), obviously improving the stability of the electrophoretic display solution (the sedimentation rate is 8-14% after standing for 30d), and creating the condition for realizing industrial application.

The invention discloses a pixel circuit, a driving method thereof, a display panel and a display device. The pixel circuit includes: a data writing module, a switch control module, a reset module, a light-emitting control module, a first light-emitting device, and a second light-emitting device , and a drive control module; by setting the first light-emitting device and the second light-emitting device, and the second electrode of the first light-emitting device is coupled to the first electrode of the second light-emitting device, the first electrode of the first light-emitting device and the second The second electrode of the light-emitting device is coupled, and through the cooperation of the data writing module, the switch control module, the reset module, the light-emitting control module and the driving control module, the time-sharing display of the first light-emitting device and the second light-emitting device can be controlled, which can avoid Static display for a long time, so as to avoid the afterimage problem of the OLED display, prolong the display life of the OLED display, and improve the display performance of the OLED display.
