An electron emission device includes a substrate, cathode and gate electrodes placed on the substrate in an insulated manner, and electron emission regions electrically connected to the cathode electrodes. Each of the cathode electrodes includes a line electrode having a groove at one lateral side surface thereof, and isolation electrodes formed on the substrate exposed through the groove such that the isolation electrodes are isolated from the line electrode. The electron emission regions are placed on the isolation electrodes and a resistance layer electrically connects the isolation electrodes to the line electrode.

摘要:
A method of recycling a solution, the method including: filtering a solution used in chemical bath deposition; reinflowing the filtered solution to a bath; and inflowing an alkali solution to the bath to maintain a concentration of an alkaline material in the filtered solution in a range of about 1.0 M to about 3.5 M, is disclosed. A solar cell formed by the method and a deposition apparatus are also disclosed. By the method of recycling a solution, a solar cell including a buffer layer formed with a solution which has been used multiple times may be formed to have an efficiency almost the same as that of a solar cell including a buffer layer formed with a solution provided for the first time before filtering.

A deposition apparatus and a method for recycling a solution. The deposition apparatus includes a bath in which a solution used in a chemical bath deposition (CBD) method is filled, a tank in which the solution used in the CBD method is temporarily stored, and a filter unit for filtering the solution stored in the tank to be reused in the CBD method again. Thus, when a buffer layer is formed by the CBD method, the number of times of reusing the solution for forming the buffer layer may be increased.
摘要:
A plasma display panel comprising first and second discharge spaces. Each discharge space is defined by first and second structures between first and second substrates and is configured to substantially contain a display discharge within at least a portion of the discharge space. Each discharge space has a first width at a first distance from the first substrate toward the second substrate and has a second width at a second distance from the first substrate toward the second substrate. A non-discharge space is provided between the first and second discharge spaces, wherein the height of the discharge space between the first and second substrates is greater than the corresponding height of the non-discharge space between the first and second substrates.
