Electroluminescent display panel and pixel structure thereof

Abstract

The invention discloses an electroluminescent display panel, which comprises a blue electroluminescent element, a red electroluminescent element, a green electroluminescent element, a first power line electrically connected with the blue electroluminescent element, a second power line electrically connected with the red electroluminescent element, and a third power line electrically connected with the green electroluminescent element. The first power line has a first wire width, the second power line has a second wire width, the third power line has a third wire width, wherein the first wire width is greater than the second wire width, and the first wire width is greater than the third wire width. The invention also discloses a pixel structure of the electroluminescent display panel.

Description

technical field [0001] The invention relates to an electroluminescent display panel and its pixel structure, in particular to an electroluminescent display panel with unequal line width designed power lines and its pixel structure. Background technique [0002] Electroluminescent display, due to its light and thin size, high resolution, high contrast ratio, power saving and active light emission, has surpassed liquid crystal display and has become the mainstream product of the next generation flat and thin display. [0003] Please refer to figure 1 . figure 1 A schematic circuit structure diagram of a known pixel structure of an electroluminescent display panel is shown. Such as figure 1 As shown, the conventional electroluminescence display panel 10 includes a plurality of pixel structures 12 , and each pixel structure 12 includes a pixel switch element 14 , a driving switch element 16 , a storage capacitor Cs and an electroluminescence element EL. The gate, source and ...

Problems solved by technology

However, due to the different luminescent properties of the luminescent materials, for example, the luminous efficiencies of blue electroluminescent elements, green electroluminescent elements and red electroluminescent elements are not the same (generally speaking, the luminous efficiency of blue electroluminescent elements is generally low. (Green electroluminescence element and red electroluminescence element), plus the human eye's acceptance of different colors of light is also different, so the equal-width power line design increases the overall voltage drop of the known electroluminescence display panel 10 , and the problem of uneven display brightness of the electroluminescent display panel 10 is more serious
