    • The present invention relates to an organic light emitting display, and an aspect of the invention is to minimize the phenomenon of reduction in luminance of the organic light emitting diode display, by dividing an analog data to a positive data and a negative data, applying the same data with different polarities to the control electrode of a driving transistor, and preventing the deterioration of threshold voltage of the driving transistor.For this purpose, the present invention discloses an organic light emitting display including a frame memory that stores data of one or more frames, doubles the frequency of the frame data, and repeatedly outputs the frame data; a look-up table memory that divides the frame data doubled and outputted from the frame memory, into two digital input signals such as a positive data and a negative data, and outputs the data; and a digital-analog converter that receives the positive data and negative data outputted from the look-up table memory, converts the data to analog data, and outputs the analog data.
    • 本发明涉及一种有机发光显示器,本发明的一个方面是通过将模拟数据分割为正数据和负数据来最小化有机发光二极管显示器的亮度降低现象, 与驱动晶体管的控制电极具有不同极性的相同数据,并且防止驱动晶体管的阈值电压的劣化。 为此,本发明公开了一种有机发光显示器,包括存储一个或多个帧的数据的帧存储器,使帧数据的频率加倍,并重复输出帧数据; 将从帧存储器加倍并输出的帧数据分割为两个数字输入信号,例如正数据和负数据的查找表存储器,并输出数据; 以及数字模拟转换器,其接收从查找表存储器输出的正数据和负数据,将数据转换为模拟数据,并输出模拟数据。

    • Disclosed herein is an apparatus for correcting the position of teeth used in dentistry. The apparatus for correcting the position of teeth is constructed in a structure in which an implantation unit is securely fixed to a palate, e.g., the roof of a mouth, the bony tissue of which is very excellent and the soft tissue thickness of which is small, using a fixing source, opposite suspension parts are suspended by opposite buccal molar areas to draw front teeth backward, whereby the movement of teeth at the molar tooth areas is prevented, and therefore, reimplantation is unnecessary, application points for drawing the front teeth, including the molar teeth, backward are located at the buccal molar areas, whereby the application of a force (a correction force) is easy, it is possible to induce natural extension of a dental arch (an arch-shaped area where teeth are implanted), and the teeth are moved backward to correct the irregularities of teeth, whereby it is possible to considerably reduce a possibility of tooth extraction.
    • 本文公开了一种用于校正牙齿中使用的牙齿位置的装置。 用于校正牙齿位置的装置构造成其中植入单元被牢固地固定到腭部的结构,例如口腔的顶部,其骨组织非常优异,并且其软组织厚度小 使用固定源,相对的悬挂部分通过相对的颊摩擦区域悬挂以向前拉前牙,从而防止在摩擦齿区域的齿的移动,因此不需要再植入,用于拉拔前牙的应用点, 包括臼齿,向后位于颊部摩擦区域,由此施加力(矫正力)容易,可以引起牙弓(牙嵌入的弓形区域)的自然延伸, 并且齿向后移动以校正齿的不规则性,由此可以显着降低拔牙的可能性。
