Abstract: An electrode and an organic electroluminescent device using the same are provided. The electrode comprises a first conductive layer (1), a second conductive layer (2) and a third conductive layer (3) that are arranged in a stacked manner The second conductive layer (2) has a single-layer structure or multi-layer composite structure formed by at least one of alkali earth metal, alkali earth metal alloy and alkali earth metal compound, and the third layer (3) has a work function of less than 3 eV. The respective conductive layers of the electrode can compensate with respect to the defects in one another, thereby making the performance of the electrode more stable. In the meantime, because the work function of the third conductive layer (3) is less than 3 eV, the barrier of organics-metal interface can be effectively reduced for guiding the electron injection, thereby increasing the light-emitting efficiency of device. Also, because the electrode has relatively good transmittance, it can be used as a transparent electrode.

Abstract: The application relates to a display panel, a display screen and a display terminal. A first electrode in the display panel has a one-to-one correspondence with a pixel circuit, the second electrode is a full-surface electrode, and a scan line and a data line are connected to the pixel circuit, and the scan line controls the turning on and turning off of the pixel circuit. When the pixel circuit is turned on, the data line provides a driving current for the first electrode to control the sub-pixel to emit light. The pillar on the pixel defining layer at least partially covers the active layer in the pixel circuit. The pillar is made of a non-specular reflective material; and the reflectivity of the material of the pillar is less than the reflectivity of a metal, and/or the material of the pillar is a low light transmittance material.

Abstract: The present application provides a display device, a display panel and a capacitance compensation method thereof. A standard for performing a capacitance compensation on row scan lines in a first display region having fewer pixel units is that total load capacitance of a row scan line of a row adjacent to a second display region is equal to self-load capacitance of a row scan line of any row in the second display region, and that total load capacitance of each of the row scan lines decreases smoothly from the row adjacent to the second display region to a row away from the second display region.
