- S01 initial display state
- S02 standby display
- “before setting” indicates a state in which various types of information are not set by the user via the setting menu. Therefore, not only when the power supply is turned on for the first time immediately after shipment, but also before the setting process is performed, the second and subsequent standby displays are also in this state. An example of specific display contents in each state will be described later.
- the state transits to the light source on-display (S03) state. From this state, when the user performs a setting process via the setting menu and then the light source 13 is turned off and video projection is finished, the state transitions to a state of cooling display (S04) after the light source is turned off. When the cooling is completed, the state transitions to a standby display (after setting) (S05) state. Even when the light source 13 is turned off from the above-described light source lighting display (S03) state, the display is switched directly to the standby display (after setting) (S05) state without performing the cooling display (S04) after the light source is turned off. Good. When the light source 13 is turned on again in the standby display (after setting) (S05) state, the display returns to the light source lighting display state (S03).
- the function of the nonvolatile display device 17 can maintain display of predetermined information even in the absence of power supply.
- FIG. 14 is a diagram showing an outline of an example of transition of screen display contents when power supply is forcibly turned off from other than standby. Since the normal screen transition in FIG. 13 and S01 to S06 are the same, description thereof will be omitted.
- the power supply is forcibly turned off when the projection display 1 is in an operation other than standby, that is, in the state of light source on display (S03), or in the state of cooling display after the light source is turned off (S04).
- the supply line 26 is disconnected, the state transits to a state of forced power supply OFF display (S07) from other than standby.
- the function of the non-volatile display device 17 makes it possible to maintain display of predetermined information even when there is no power supply.
- FIG. 15 is a diagram showing an outline of an example of transition of screen display contents when an error is detected. Since the normal screen transition in FIG. 13 and S01 to S06 are the same, description thereof will be omitted. If the processing unit 18 detects an error in a state where power is supplied to the projection display apparatus 1, that is, in each state of standby display (before setting) (S02) to standby display (after setting) (S05), an error will occur. Transition to the display (S08) state. In the case of the light source on display (S03) state, in addition to the error detection, when the light source 13 is turned off, the state is changed to the error display (S08) state.
- the state transits to the power supply OFF display from error (S09) state. Also in this case, the function of the non-volatile display device 17 makes it possible to maintain display of predetermined information even when there is no power supply.
- Table 1 shows “display switching” as an example of display contents in the screen transition when various information is displayed with the entire display area of the nonvolatile display device 17 as one area as shown in FIGS. Two patterns of “Example 1-1” and “Display switching example 1-2” are shown. “Display switching example 1-1” is a pattern in which the owner identification display shown in FIG. 3 is maintained even after the power supply is turned OFF. “Display switching example 1-2” indicates that the power supply is OFF. This is a pattern for maintaining the replacement part related display shown in FIG.
- any pattern basically displays nothing at the time of shipment (S01) or displays arbitrary information set in advance as other display.
- the model attribute identification display shown in FIG. 7 may be used.
- the standby display (before setting) (S02) nothing is displayed or other display is performed.
- the model attribute identification display shown in FIG. 7 may be used.
- the display content of the shipping display (S01) may be maintained as it is, or the display may be switched. For example, nothing is displayed in the shipping display (S01), but the display may be switched to the model attribute identification display in the standby display (before setting) (S02) when the power supply is turned on.

Abstract
Description
図1は、本発明の一実施の形態である投射型映像表示装置の構成例について概要を示したブロック図である。また、図2は、本実施の形態の投射型映像表示装置の外観の例について概要を示した斜視図である。図1において、投射型映像表示装置1は、例えば、外部電源供給3から電力の供給を受けて、スクリーン4に対して映像を投射して拡大表示する液晶プロジェクタ等である。
図3~図12は、不揮発性表示デバイス17の画面に表示される内容の例について概要を示した図である。図3は、所有者識別表示の例について概要を示した図である。所有者識別表示は、当該投射型映像表示装置1を所有する組織名や担当者名、連絡先等の所有者を識別する表示であり、表示内容は、ユーザが後述する設定メニュー画面を介して登録することができるものとする。
図13~図15は、処理部18の制御による不揮発性表示デバイス17の画面表示内容の遷移の例について概要を示した図である。図13は、正常時の画面表示内容の遷移の例について概要を示した図である。まず、初期状態の出荷時表示(S01)の状態から最初に電力供給がONされる、すなわち外部電源供給3との間で電力供給線26が接続されると、スタンバイ表示(設定前)(S02)の状態に遷移する。ここで「設定前」とは、設定メニューを介したユーザによる各種情報の設定処理がされていない状態を指す。したがって、出荷直後の初回の電力供給ON時はもちろん、設定処理がされる前であれば2回目以降のスタンバイ表示についてもこの状態となる。なお、各状態での具体的な表示内容の例については後述する。
図16~図19は、不揮発性表示デバイス17の表示内容等を設定する設定メニュー画面の例について概要を示した図である。設定メニュー画面50は、例えば、操作入力部23を介したユーザによる指示によりスクリーン4上に投射映像41として投射され、操作入力部23を介したユーザの操作による値や設定内容の登録を受け付ける。
