Title (EN) WINDSHIELD
(FR) PARE-BRISE
(JA) ウインドシールド
Abstract:
(EN) The present invention pertains to a windshield that has a display region on which information is projected by means of light emitted from a head-up display device, the windshield being provided with: an outer glass plate; an inner glass plate disposed so as to face the outer glass plate; and an intermediate film interposed between the outer glass plate and the inner glass plate, wherein grid points are defined at a pitch of at most 20 mm within a measurement region, and, when wedge angle measurement is taken at the respective grid points using an interferometer in 240-by-240 pixels or more, the difference between the largest value and the smallest value of said wedge angles is not more than 0.32 mrad.
(FR) La présente invention concerne un pare-brise qui a une région d'affichage sur laquelle des informations sont projetées au moyen de la lumière émise à partir d'un dispositif d'affichage tête haute, le pare-brise comportant : une plaque de verre externe ; une plaque de verre interne disposée de façon à faire face à la plaque de verre externe ; et un film intermédiaire interposé entre la plaque de verre externe et la plaque de verre interne, des points de grille étant délimités à un pas d'au plus 20 mm à l'intérieur d'une région de mesure, et, lorsqu'une mesure d'angle de coin est prise au niveau des points de grille respectifs à l'aide d'un interféromètre dans 240 par 240 pixels ou plus, la différence entre la valeur la plus grande et la valeur la plus petite desdits angles de coin n'est pas supérieure à 0,32 mrad.
(JA) 本発明は、ヘッドアップディスプレイ装置から照射される光によって情報が 投影される表示領域を有するウインドシールドであって、外側ガラス板と、前記外側ガラス板と対向配置される内側ガラス板と、前記外側ガラス板と内側ガラス板との間に配置される中間膜と、を備え、前記測定領域内に20mm以下のピッチで格子点が規定され、干渉計により、ピクセル数240×240以上で、前記各格子点における楔角を測定したとき、当該楔角の最大値と最小値との差が、0.32mrad以内である。
