Abstract
(EN)
A Micro LED display panel, comprising: a GOA driving circuit, multiple data lines Dm, multiple scanning lines G(n), and multiple pixel units. The multiple scanning lines G(n) and the multiple data lines Dm are arranged in a criss-cross manner, a pixel region (100) is enclosed between two adjacent scanning lines G(n) and two adjacent data lines Dm to form multiple pixel regions (100) arranged in an array manner, and each pixel region (100) is provided with one pixel unit. The GOA driving circuit comprises multiple cascaded GOA units (200). One level of GOA unit (200) is provided in each row of pixel regions (100), wherein the GOA unit (200) between the n-th row of scanning lines G(n) and the (n + 1)-th row of scanning lines G(n + 1) is the n-th level of GOA unit (200), and the n-th level of GOA unit (200) is respectively connected to the n-th row of scanning lines G(n) and the (n + 1)-th row of scanning lines G(n + 1). The GOA units (200) of the GOA driving circuit are respectively provided in the pixel regions (100), so that the size of a bezel is reduced, and the screen-to-body ratio is improved.

La présente invention concerne un panneau d'affichage à micro-DEL, comprenant : un circuit d'attaque GOA, de multiples lignes de données Dm, de multiples lignes de balayage G(n), et de multiples unités de pixels. Les multiples lignes de balayage G(n) et les multiples lignes de données Dm sont disposées de manière croisée, une région de pixels (100) est entourée par deux lignes de balayage G adjacentes (n) et deux lignes de données Dm adjacentes pour former de multiples régions de pixels (100) agencées en réseau, et chaque région de pixels (100) est pourvue d'une unité de pixels. Le circuit d'attaque GOA comprend de multiples unités GOA montées en cascade (200). Un niveau d'unité GOA (200) est disposé dans chaque rangée de région de pixels (100), l'unité GOA (200) située entre la nième rangée de lignes de balayage G(n) et la (n + 1)ième rangée de lignes de balayage G(n +1) étant le nième niveau de l'unité GOA (200), et le nième niveau de l'unité GOA (200) étant respectivement connecté à la nième rangée de lignes de balayage G(n) et à la (n + 1)ième rangée de lignes de balayage G(n + 1). Les unités GOA (200) du circuit d'attaque GOA sont respectivement disposées dans les régions de pixels (100), de telle sorte que la taille d'un cadran est réduite et le rapport écran-corps est amélioré.
