A method of driving a head mounted display is provided. The method derives a position adjustment data by displaying a binocular position adjustment image on a left-eye panel region and a right-eye panel region, derives a size adjustment data by displaying a binocular size adjustment image on the left-eye panel region and the right-eye panel region, generates a luminance adjustment data based on a difference between a left-eye and a right-eye luminance perception data, converts an image source into an input image data based on the position adjustment data, the size adjustment data, and the luminance adjustment data, and displays an image corresponding to the input image data.

A transparent display panel includes a transparent display structure and a light transmittance adjusting structure. The transparent display structure includes a display region and a transmittance region. The light transmittance adjusting structure is located over or under the transparent display structure. The light transmittance adjusting structure includes a volume changeable material of which a volume is changed in response to intensity of incident light or a photochromic material of which a coloring degree is changed in response to the intensity of incident light. The transparent display panel effectively improves quality of an image displayed on the transparent display panel by maintaining or adjusting a contrast ratio of the image according to the intensity of the incident light.

A display device includes a plurality of pixels arranged in matrix, a plurality of gate lines, a plurality of data lines, and a gate driver connected to the plurality of gate lines. The gate driver receives a first scan start signal, a second scan start signal and clock signals and outputs a gate-on voltage to each of the plurality of gate lines. The gate driver outputs the gate-on voltage to the plurality of gate lines such that the gate-on voltages do not overlap with each other when the gate driver receives the first scan start signal. The gate driver outputs the gate-on voltage to at least two of the gate lines at substantially the same time when the gate driver receives the second scan start signal.

A display panel driving apparatus and a method of driving the same are provided, and, in particular, a gate driver and a method of driving the gate driver. The gate driver includes a decoder that decodes gate line selection data and that generates a gate line selection signal. A gate driving circuit generates a gate driving signal in a pre-charging phase and a driving phase in response to the gate line selection signal and a pre-charging control signal that controls an off-state of non-selected gate lines. In a time period of the driving phase in which a gate line is not selected, a node that has been in a floating state is held to a target voltage level in response to a hold control signal. The hold control signal is generated based upon a timing relationship between the gate line selection signal and the pre-charging control signal.

A method and apparatus for generating a low reference voltage having low power consumption characteristics is provided. A reference voltage generating apparatus includes a constant current source circuit which generates a reference current. A load circuit is connected to the constant current source circuit and generates a voltage which is proportional to the reference current. A current branch circuit removes a portion of temperature-invariant current components included in the reference current from a connection terminal of the constant current source circuit and the load circuit to a ground terminal through a current branch which is different from a current branch of the load circuit.

Reference voltage generating apparatus and method thereof for removing temperature invariant current components from a reference current

A photoresist composition for immersion lithography and a method of forming a photoresist pattern using the photoresist composition are disclosed. The photoresist composition includes a photosensitive polymer including a cycloaliphatic group blocked with at least two cyclic acetal groups as a side chain, a photoacid generator and an organic solvent. The hydrophobic photoresist composition may be changed into the hydrophilic photoresist composition by an exposure process. Thus, before the exposure process, the photoresist composition may be insoluble in a liquid for the immersion lithography. After the exposure process, an exposure portion of a photoresist film formed using the photoresist composition may be effectively dissolved in a developing solution to form a uniform photoresist pattern.
