Problems solved by technology

As a result, there is a problem that the manufacturing cost increases
[0020] Furthermore, since the video signal is corrected using a huge amount of data for each pixel, the correction process at the time of light emission driving of each pixel becomes complicated.
[0021] As mentioned above, in the above-mentioned prior art, when realizing an organic electroluminescent display that suppresses uneven brightness, there are the following problems. Post data processing complex topics

Abstract

Provided is a display device which reduces the manufacturing costs and can correct uneven luminance caused by non-uniformity in the element characteristics by simple measurement and corrective processes. The display device is comprised of a plurality of pixels which include light-emitting elements and drive elements; a plurality of data lines which supply the data voltages corresponding to the voltages supplied to the drive electrodes; a data line drive circuit which supplies the data voltages to the plurality of data lines; a memory (102) which stores the luminance gain for setting the luminance corresponding to the image signal to the specified standard luminance for each pixel, and stores the information of the representative conversion curve corresponding to the voltage-luminance characteristics shared by the plurality of pixels to be shared by the plurality of pixels; and a correction conversion block (601) which reads out and calculates the corresponding luminance gain with respect to the luminance signal from the memory (102) and corrects to the specified standard luminance, and converts the luminance signal of each corrected pixel into a voltage signal based on the specified information corresponding to the representative conversion curve stored in the memory (102).

Description

technical field [0001] The present invention relates to a display device, a method for manufacturing the display device, and a control method, and more particularly, to a display device using a current-driven light-emitting element, a method for manufacturing the display device, and a control method for the display device. Background technique [0002] An image display device (organic electroluminescence display) using an organic electroluminescence element (OLED: Organic Light Emitting Diode: Organic Light Emitting Diode) is known as an image display device using a current-driven light emitting element. This organic electroluminescent display has advantages of good viewing angle characteristics and low power consumption, and has attracted attention as a candidate for a next-generation flat panel display (FPD: Flat Panal Display). [0003] Generally, in an organic electroluminescence display, organic electroluminescence elements constituting pixels are arranged in a matrix. ...
