2results about How to "Avoid uneven brightness" patented technology

This application relates to the field of aerosol generation devices, and provides a display component and atomizing device. The display component includes: a first display element having an adjacent display surface and a light-incident side surface; and a second display element having a light-emitting element for emitting light towards the light-incident side surface. In this application, the light-emitting element emits light towards the light-incident side surface adjacent to the display surface. After entering from the light-incident side surface of the first display element, the light is reflected or refracted internally by the first display element, and then uniformly diffused or dispersed across the entire display surface. By optimizing the incident direction and transmission path of the light, this application effectively avoids the problem of uneven brightness on the display surface caused by the light-emitting element directly irradiating the surface opposite to the display surface of the first display element, making it easier for the display surface to achieve uniform light reception and improving the uniformity of the display surface brightness.

This application provides a display device and its driving method. The display device includes a display panel. The display panel includes a plurality of pixel units. Each pixel unit includes a first sub-pixel and at least one second sub-pixel. The first sub-pixel includes a first driving circuit and a first light-emitting diode. The first driving circuit includes a first pulse amplitude modulation control module, a first transistor, and a second transistor. The second sub-pixel includes a second driving circuit and a second light-emitting diode. The second driving circuit includes a second pulse amplitude modulation control module, a second pulse width modulation control module, a third transistor, and a fourth transistor. The technical solution of this application reduces the number of data signal lines, lowers the complexity of the driving circuit, improves color point stability and brightness uniformity, reduces transient current peaks, and improves the reliability of the display device.
