  • Publication number: 20240389397
    Abstract: A light emitting display apparatus includes an insulating layer arranged on a substrate. The insulating layer includes a trench. A first electrode is arranged on the insulating layer. A light emitting layer is arranged on the insulating layer and the first electrode. A separator is arranged between the insulating layer and the light emitting layer. The separator covers at least one sidewall of the trench. A second electrode is arranged on the light emitting layer. The separator includes a recess portion having at least a portion concavely defined in a horizontal direction on the substrate.

  • Patent number: 11348504
    Abstract: A display apparatus includes a display panel; and a display driver integrated circuit (DDI) chip coupled to the display panel, the DDI chip being configured to generate a display driving signal for driving the display panel based on image data. The DDI chip may include: a first embedded memory device embedded in the DDI chip and configured to store compensation data for compensating for electrical and optical characteristics of a plurality of pixels included in the display panel; a timing controller configured to control signals for driving the display panel, and to generate a data control signal based on the image data and the compensation data; and a data driver configured to provide a data voltage to the display panel according to the data control signal. The first embedded memory device may not include static random access memory (SRAM).

  • Patent number: 9859158
    Abstract: A method for manufacturing a semiconductor device includes forming a device isolation layer in a substrate to define an active region, forming a gate insulating layer covering at least a portion of the active region, forming a gate electrode on the gate insulating layer, and forming an interlayer insulating layer on the gate electrode. The gate insulating layer includes a first portion overlapping with the active region and a second portion overlapping with the device isolation layer. The forming of the gate insulating layer includes etching at least a part of the second portion of the gate insulating layer to thin the part of the second portion of the gate insulating layer.
