Abstract

The invention discloses a compensation voltage calculation method, a compensation voltage calculation device, a voltage compensation method, a voltage compensation system, and a driving chip. The compensation voltage calculation method includes the following steps that: the aspect ratio x / y of a display panel and the number N of rows of sub-pixel circuits are obtained; the number Ny of rows of sub-pixel circuits which are simulated in width is calculated according to the aspect ratio x / y of the display panel and the number N of the rows of the sub-pixel circuits; the voltage difference value deltaV of each row of sub-pixel circuits is calculated according to the number Ny of the rows of the sub-pixel circuits which are simulated in width, the number N of the rows of the sub-pixel circuitsand PCD (Panel Crack Detection) voltage difference; and the voltage attenuation value deltaVi of the i-th row of sub-pixel circuits is determined according to the calculated voltage difference value deltaV of each row of sub-pixel circuits, so that the voltage attenuation value deltaVi of the i-th row of sub-pixel circuits can be used to compensate the voltage value of the data voltage of the i-throw of sub-pixel circuits. The overall display screen of a display panel is more uniform, and the display quality of the panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a compensation voltage calculation method and device, a compensation method and system, and a driver chip. Background technique [0002] The current active-matrix organic light emitting diode (AMOLED) display panel, especially the large-sized AMOLED display panel, due to the influence of the wiring method and wiring impedance of the driving power supply voltage, reaches each effective display unit. (Sub-pixel circuits) often have different driving power supply voltages, resulting in uneven display images and affecting the overall display quality of the AMOLED display panel. [0003] In order to ensure the overall display quality of the AMOLED display panel, the existing technology may adopt the following methods: 1), design a special pixel circuit and match the corresponding control sequence diagram, and compensate the driving power supply voltage to eliminate the drivin...
