Abstract
(EN)
A display panel (10), comprising a thin film transistor, a first circuit (11), and a second circuit (12). The first circuit (11) comprises a first output end (111), a first resistor (R1), and a second resistor (R2) that are sequentially connected in series. The first output end (111) is configured to output a control voltage (VGH) to the thin film transistor. The second circuit (12) comprises a third resistor (R3) and a compensation control switch (S1) that are connected in series. When the temperature is lower than a preset temperature threshold, the compensation control switch (S1) is closed, and the third resistor (R3) and the second resistor (R2) are connected in parallel so as to increase the control voltage (VGH) output from the first output end (111) to the thin film transistor.

L'invention concerne un panneau d'affichage (10), comprenant un transistor en couches minces, un premier circuit (11) et un deuxième circuit (12). Le premier circuit (11) comprend une première extrémité de sortie (111), une première résistance (R1) et une deuxième résistance (R2) qui sont successivement connectées en série. La première extrémité de sortie (111) est conçue pour délivrer une tension de commande (VGH) au transistor en couches minces. Le deuxième circuit (12) comprend une troisième résistance (R3) et un commutateur de commande de compensation (S1) qui sont connectés en série. Lorsque la température est inférieure à un seuil de température prédéfini, le commutateur de commande de compensation (S1) est fermé, et la troisième résistance (R3) et la deuxième résistance (R2) sont connectées en parallèle de manière à accroître la sortie de tension de commande (VGH) en provenance de la première extrémité de sortie (111) et à destination du transistor en couches minces.
