Data writing unit and data writing method, driving chip and display device

Abstract

The invention provides a data writing unit, a data writing method, a driving chip and a display device. The data writing unit comprises a first logical operation module, a second logic operation module and a data output end; the first logical operation module and the second logical operation module are connected to the same data output end in parallel; wherein the first logical operation module isused for writing a first circuit parameter, the second logical operation module is used for writing a second circuit parameter under a preset condition to replace the first circuit parameter, and thewriting power of the second logical operation module is greater than that of the first logical operation module. According to the data writing unit provided by the invention, the purposes of shortening the data writing time and reducing the deviation between the actually written data voltage value and the theoretically required data voltage value on the premise that the normal work of the to-be-written unit is not influenced are achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data writing unit, a data writing method, a driving chip and a display device. Background technique [0002] Currently, in existing display panel circuits (such as active matrix light-emitting diode display panel circuits) and other array circuits (such as memory array circuits), it is often necessary to write data voltages into storage capacitors. The process of writing data is the process of charging the storage capacitor, and the writing time of the data voltage is usually determined by the operating frequency of the array and the size of the array. Specifically, under the same array size, the higher the array operating frequency, the shorter the data voltage writing time; under the same array operating frequency, the larger the array size, the shorter the data voltage writing time. [0003] However, in the actual writing process, due to the limitation of circuit st...
