Embodiment 1

[0032]Such asfigure 1 As shown, the OLED's intelligent dynamic compensation system includes:

[0033]The acquisition unit is configured to obtain the actual display brightness of each sub-pixel of the OLED display panel in the actual input gray scale, and calculate the corresponding relationship between the actual input gray scale of each sub-pixel and the actual display brightness;

[0034]The calculation unit is configured to determine the target input grayscale when each sub-pixel is displayed in displaying the target display brightness based on the corresponding relationship between the actual input gray scale and the actual display brightness of each sub-pixel.

[0035]Dynamic compensation model unit, configured to establish a dynamic compensation model, the target display brightness, and its corresponding target input grayshade as training data, training dynamic compensation model, and complete the model creation.

[0036]Specifically, the present invention utilizes the actual display bri...

Embodiment 2

[0038]On the basis of the previous embodiment, the dynamic compensation model is dynamically compensated according to the current actual input gray scale of each sub-pixel of the current OLED display panel, performs dynamic compensation for dynamic compensation of the actual display of each sub-pixel of the current OLED, so that the current OLED sub-pixels The actual display brightness is equal to the actual input grayscale corresponding to the actual input grayscale corresponding to each sub-pixel of OLEDs.

[0039]Specifically, the so-called grayscale is a change in brightness between the brightest and darkest to distinguish between several parts. To facilitate the screen brightness control of the signal input. Each digital image is made up of many points, which is also known as pixels, usually each pixel can present many different colors, which are three sons of red, green, blue (RGB). Pixel consists of pixels. Each sub-pixel, the light source behind it can show different brightness...

Embodiment 3

[0041]On the basis of the previous embodiment, the actual display brightness of each sub-pixel of the OLED display panel is in the actual input gray scale comprises: according to the OLED display panel acquired by the optical acquisition device, in the actual input actual input gray scale The display image acquires the actual display brightness of each sub-pixel of the OLED display panel in the actual input gray scale.

[0042]Specifically, the pixel is composed of the small square of the image, and these small squares have a clear position and the dispensed color value, the small square color, and the position determines that the image appears.

[0043]The pixels can be regarded as unsearbable units across images or elements. Insembled means that it is not able to cut into smaller units or elements, which exists with a single color. Each dot matrix image contains a quantity of pixels, which determine the size of the image on the screen.

Abstract

The invention relates to the technical field of LEDs, in particular to an intelligent dynamic compensation system and method for an OLED. The system comprises: an obtaining unit configured to obtain actual display brightness of each sub-pixel of an OLED display panel under an actual input gray scale and calculate a corresponding relationship between the actual input gray scale and the actual display brightness of each sub-pixel and a calculation unit configured to determine a target input gray scale of each sub-pixel when the sub-pixel displays the target display brightness according to a corresponding relationship between the actual input gray scale of each sub-pixel and the actual display brightness; according to the invention, the compensation model is determined by using the actual display brightness and the target display brightness, the brightness of the OLED is compensated by using the compensation model, and in the compensation process, errors caused in the compensation processare compensated by using error compensation, so that the compensation accuracy is further improved.

Description

Technical field[0001]The invention belongs to the field of LED technology, and specific to the intelligent dynamic compensation system and method of OLD.Background technique[0002]OLED (OrganicLight-Emitting Diode), also known as an organic electrical laser display, organic light-emitting semiconductor (Organadelectroluminesence Display, OLED). The OLED belongs to a current type organic light-emitting device, which is a phenomenon that is luminescence through the injection and composite of carriers, and the luminous intensity is proportional to the injected current. Under the action of an electric field, the electrons generated by the anode generated by the anode will move, respectively, respectively, injecting the hole transport layer and the electron transport layer, migrating to the light-emitting layer. When the two meet in the light-emitting layer, the energy exciton is generated, so that the excitation of the luminescent molecule eventually produces visible light.[0003]However,...
