Description

そして、図9LCDの静電容量型近接センサ26は、例えば以下のように動作する。まず、導体線26bに人の指等の外部の導電体が近接すると、導体線26bと外部の導電体との間に静電的な容量結合が発生する。このとき、導体線26bに新たな電気的容量が付加されるために、給電部26aに接続された外部の制御IC,LSI等へ導体線26bから反射してくる電流値(電荷量)が変化する。その変化した電流値を電圧値の変化として制御IC,LSI等によって検知することによって、外部の導電体の近接を検知することができる。 The capacitive proximity sensor 26 of the LCD of FIG. 9 operates as follows, for example. First, when an external conductor such as a human finger approaches the conductor line 26b, electrostatic capacitive coupling occurs between the conductor line 26b and the external conductor. At this time, since a new electric capacity is added to the conductor line 26b, the current value (charge amount) reflected from the conductor line 26b to the external control IC, LSI, etc. connected to the power supply portion 26a changes. To do. By detecting the changed current value as a change in voltage value by a control IC, LSI or the like, the proximity of an external conductor can be detected.

本発明は、上記問題点に鑑みて完成されたものであり、その目的は、周囲の電子部品、回路配線等にEMIを生じさせたり、逆に周囲の電子部品、回路配線等からEMIを受けることのない近接センサを用いた表示装置とすること、また、表示パネルの中央部等に近接した、赤外線検知ユニット設置位置から横方向に離れた人の手等を、良好に検知することができる近接センサを用いた表示装置とすることである。 The present invention has been completed in view of the above problems, and an object, around the electronic components, or cause EMI on the circuit wiring or the like, electronic components around the contrary, the EMI from the circuit wiring or the like It is possible to make a display device using a proximity sensor that does not receive, and to detect well, such as a person's hand that is close to the center of the display panel, etc., away from the infrared detection unit installation position in the lateral direction. This is a display device using a proximity sensor that can be used.

本発明の表示装置は、表示面に近接する被検知体を検知する赤外線検知ユニットが左右両端に設けられた表示パネルを有しており、前記赤外線検知ユニットは、赤外線受光素子とそれよりも数が多い赤外線発光素子を備えているとともに、前記赤外線発光素子が前記表示面の中心部の法線方向に向くように傾けて設置されている構成である。 Display device of the present invention has a display panel that infrared sensing unit for detecting a detected object is provided on both left and right ends in proximity to the display surface, the infrared sensing unit, the infrared light receiving element and than The infrared light emitting device includes a large number of infrared light emitting devices, and the infrared light emitting devices are inclined and installed so as to face the normal direction of the center portion of the display surface.

本発明の表示装置は、表示面に近接する被検知体を検知する赤外線検知ユニットが左右両端に設けられた表示パネルを有しており、赤外線検知ユニットは、赤外線受光素子とそれよりも数が多い赤外線発光素子を備えているとともに、赤外線発光素子が表示面の中心部の法線方向に向くように傾けて設置されていることから、周囲の電子部品、回路配線等にEMIを生じさせたり、逆に周囲の電子部品、回路配線等からEMIを受けることがなく、また表示パネルの表示面の中央部等に近接した、赤外線検知ユニット設置位置から横方向に離れた人の手等の被検知体を、良好に検知することができる。 Display device of the present invention has a display panel that infrared sensing unit for detecting a detected object is provided on both left and right ends in proximity to the display surface, the infrared sensing unit, the number than the infrared receiving elements Infrared light emitting elements are installed, and the infrared light emitting elements are tilted so that they are oriented in the normal direction of the center of the display surface. This causes EMI in surrounding electronic components and circuit wiring. On the contrary, it does not receive EMI from surrounding electronic parts, circuit wiring, etc., and is close to the center of the display surface of the display panel, etc. The detected object can be detected satisfactorily.

本発明のLCDは、透過型LCDである場合、視認者側と反対側に、液晶表示パネル2に画像を形成するための透過光を、液晶表示パネル2の反表示面2b側から入射するバックライト4が設けられている。また本発明のLCDは、反射型LCDである場合、バックライト4は設けられていなくてもよい。このバックライト4には2つの方式がある。1つの方式は、発光素子としてのLED(Light Emitting Diode)素子が液晶表示パネル2の画面の端に配置されているエッジライト方式である。このエッジライト方式においては、液晶表示パネルの画面の端に配置されたLED素子からの光を導光板によって画面全体に導いて均一に分散させる。エッジライト方式は、最大60インチ程度までの画面において良好な光学的均一性を保持することができ、5〜10mm程度の厚さのバックライト4が実現できる。 When the LCD of the present invention is a transmissive LCD, a back light that is incident on the opposite side of the viewer side from the side opposite to the display surface 2b of the liquid crystal display panel 2 is incident on the liquid crystal display panel 2 through the transmitted light. A light 4 is provided. When the LCD of the present invention is a reflective LCD, the backlight 4 may not be provided. There are two types of the backlight 4. One method is an edge light method in which an LED (Light Emitting Diode) element as a light emitting element is arranged at the edge of the screen of the liquid crystal display panel 2. In this edge light system, light from LED elements arranged at the edge of the screen of the liquid crystal display panel 2 is guided to the entire screen by the light guide plate and uniformly dispersed. The edge light system can maintain good optical uniformity on a screen of up to about 60 inches and can realize a backlight 4 having a thickness of about 5 to 10 mm.

バックライト4は、アルミニウム等から成る金属枠体4aに嵌めこまれている。金属枠体4aはフレーム3に嵌め込み、ネジ止め等の手段で固定され、保護部材5は枠体3にネジ止め等の手段で固定される。
The backlight 4 is fitted in a metal frame 4a made of aluminum or the like. The metal frame 4a is fitted into the frame 3 and fixed by means such as screwing, and the protection member 5 is fixed to the frame 3 by means such as screwing.
