    摘要： A digital pre-distortion (DPD) power amplifying apparatus and a method for digitally controlling synchronization of the DPD power amplifying apparatus, which includes a power amplifier, a bias shifter and a DPD unit, are provided. The method includes acquiring a DPD path delay time at a path along which an input signal is fed back to the DPD unit; delaying an input signal incoming to the power amplifier by the DPD path delay time and acquiring synchronization by delaying a bias signal a predetermined number of times until the bias signal and the delayed input signal are synchronized with each other; and in response to synchronization between the bias signal and the delayed input signal being established, pre-distorting the input signal according to a feedback signal output from the power amplifier.

    摘要： The present invention relates to an optical member, comprising: a light incidence surface; and a light-emitting surface which comprises a patterned portion intended for adjusting the intensity of light and formed at an area corresponding to a light source, and an adhesive portion disposed in an area other than the patterned portion. When the optical member of the present invention is applied to a backlight unit, the patterned portion, which diffuses the light from the light source, is formed in the area corresponding to the light source so as to effectively diffuse the light from the light source into the peripheral area. Also, the optical member and a diffusion plate are stacked via an air layer in the area corresponding to the light source (the area in which the patterned portion is disposed), and the optical member and the diffusion plate closely contact each other without an air layer in the remaining area, such that the intensity of the light transmitted between a light source portion and the peripheral portion may be adjusted with an improvement in the balance of brightness and uniformity.
