Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0025] The process of charging the display panel to the data line generally includes a pre-charging stage and a data writing stage. In the prior art, the display panel precharges the data line with a low potential (usually 0V or the voltage required to display 255 gray scales) during the precharging phase, so when entering the data writing phase, charging the data line can Start charging from the pre-charged potential, so that the data line is quickly charged to the data signal voltage. However, when the data sig...

Abstract

The invention discloses a display device and a driving method of the display device. The display device comprises a plurality of pixel circuits; a plurality of data lines connected to the plurality ofpixel circuits; at least one multi-way selection unit, wherein the multi-way selection unit comprises one input end and at least two output ends, and each output end is connected to one data line; adriving unit for inputting a precharge voltage to the input end of the multi-way selection unit in a precharge stage, and inputting at least two data signal voltages to the input end of the multi-wayselection unit in a data writing stage, wherein the precharge voltage is associated with the at least two data signal voltages, and the precharge voltage is greater than or equal to the minimum voltage in all the data signal voltages, and is less than or equal to the maximum voltage in all the data signal voltages. The invention solves the problem that pixel circuits in a display device are not fully charged in a data writing stage; the charging efficiency and the display effect are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device and a driving method for the display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED) display adopts very thin film layer of organic material and glass substrate, when current passes through, the organic material will emit light. Therefore, OLED displays can significantly save power, and can be made lighter and thinner. [0003] The OLED panel includes organic light emitting diodes, pixel circuits that drive the organic light emitting diodes to be continuously lit, and data lines that transmit data signal voltages to the pixel driving circuits. During the display process, the data line needs to be charged, that is, the data signal voltage is transmitted to the data line, and the pixel circuit drives the organic light emitting diode to emit light according to the data signal volt...
