Problems solved by technology

However, the luminescent material layer formed by inkjet coating has different film thicknesses at different positions in each pixel area due to the difference in topography, so that the emitted light from the center and edge of each pixel area has obvious color difference , resulting in a decrease in the overall color gamut performance of the display panel

Embodiment Construction

[0068]As used herein, "about," "approximately," "essentially," or "essentially" includes the stated value and the average within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the The measurement in question and the specific amount of error associated with the measurement (ie, limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or for example within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, "about", "approximately", "essentially" or "substantially" used herein can select a more acceptable range of deviation or standard deviation according to the measurement property, cutting property or other properties, and can be Not one standard deviation applies to all properties.

Abstract

The present invention discloses a display device having a plurality of pixel regions, and each pixel region includes a central pixel region and an edge pixel region located at a periphery of the central pixel region. The display device includes a substrate, a plurality of light emitting structures, and a plurality of color filter patterns. The plurality of the light emitting structures are disposed on the substrate and respectively locate in the plurality of pixel regions. A plurality of color filter patterns are disposed corresponding to the plurality of light emitting structures. The plurality of color filter patterns include a first color filter pattern and a second color filter pattern. The light transmittance of the first color filter pattern in the central pixel region is smaller than the light transmittance of the first color filter pattern in the edge pixel region. The light transmittance of the second color filter pattern in the central pixel region is greater than the light transmittance of the second color filter pattern in the edge pixel region.

Description

technical field [0001] The present invention relates to a display device, and in particular to a self-illuminating display device. Background technique [0002] In recent years, compared with the current mainstream liquid crystal display panels, organic light-emitting diode (OLED) display panels have gradually attracted various major technology companies due to their high color saturation, fast response speed and high contrast performance. investment vision. However, under the circumstances that its manufacturing cost is relatively high and its service life cannot compete with the current mainstream displays, even if the OLED display panel has the above-mentioned excellent display quality, its market share in the consumer end still cannot be significantly increased. [0003] In order to seek a lower-cost manufacturing method, the development of production equipment and related materials is one of the efforts of many manufacturers. Among them, the use of inkjet printing (Ink...
