Title: Liquid crystal display device
Inventor: SAITO YUKITO
IPC: G02F1/1335
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To improve visual characteristics without changing the characteristics of a front direction by using an optical compensation film having a lagging axis parallel or vertical with/to the transmission axis of a polarizing plate. SOLUTION: When a light advancing obliquely downward 15 transmitted through a polarizing plate 64 and an optical compensation film 66 and arrives at the surface of a liquid crystal(LC) layer 60, a linearly polarized light is rotated only by an angle of (ϕ+180 deg.) and turned to a linearly polarized light vertical to the transmission axis of a polarizing plate 62. The polarization surface of the linearly polarized light arraving at the surface of the LC layer 60 is made parallel with an LC lagging axis 70, so that the obliquely advancing light also is not influenced by the double refraction property of the LC layer 60.  Since the absorbing axis 73 of the plate 62 is parallel with the LC lagging axis of the LC layer 60, a light advancing obliquely upward 15 also turned to the linearly polarized light by the plate 62, straight advanced without being influenced by the double refraction of the LC layer 60, rotated by the film 66, and interrupted by the plate 64 because its polarization axis intersects with the transmission axis of the plate 64 at right angles.

Abstract: PURPOSE:To relieve the load of a coefficient updating section and to improve the converging speed of a coefficient by allowing a pseudo echo generating section to take partial charge with a section to cancel a steady-state echo and a section to cancel a fluctuated echo in a loudspeaker voice communication. CONSTITUTION:A test signal is used for a sound produced from a speaker 13 in the standby state and a reception voice signal is used for the sound in operation by using a switch 15. A semi-fixed pseudo echo generating section 17 generates a pseudo steady-state echo signal and an adder A18 adds a pseudo steady-state echo signal and an echo signal from a microphone 14. A variable pseudo echo generating section 11 outputs a pseudo fluctuation echo signal from a reception voice signal, an adder B12 adds the pseudo fluctuation echo signal and the output of the adder A18 to output a residual echo signal. A coefficient updating section 10 updates the coefficient of the variable pseudo echo generating section 11 based on the relative quantity between a residual echo signal and the reception voice signal. A control section 19 reads the coefficient based on the test signal in the standby state from the variable pseudo echo generating section 11 and writes it to the semi-fixed pseudo echo generating section 17.
