1 Projection Screens The right projection screen for your specific purpose

2 PRESENT SUCCESSFULLY Basics about brightness In order to view a projected picture, the picture must have a certain brightness. This brightness, of course, depends on the light in the room and the picture must be brighter than the surrounding light. It is also clear that in bright rooms, the pictures must be proportionately brighter than in dark rooms. The manufacturers of projectors specify for their devices the luminous flux in lumen which is the amount of light that leaves the objective of a projector. This light is distributed on the projection surface. The larger the projection surface, the lower the amount of light per surface unit since projectors irrespective of the size of a picture The proper projection screen makes the viewing a true pleasure for kids and adults alike.

However, this can be achieved only if projection device and screen match each other. A slide projector, e.g., needs a different screen than a beamer. Before purchasing a screen, you should therefore think carefully about the intended purpose. In the private sector, different factors are decisive than when used in the business world. When used at home, the pure pleasure of watching the presentation is in the foreground; when the screen is not required it should be hidden unobtrusively. In the business area, a stable design to withstand daily use and versatile applications is required. always produce the same amount of light. To measure the brightness of a picture, a unit is required which specifies the luminous flux per m 2 surface. This is the illuminance measured in lux. The fabric types A projection screen does not only refract the projected light but also distributes it with a single goal: send as much light as possible into the direction of the audience. There are two types of projection screens: diffuse (Basiclux/Valuelux) reflective (Starlux/Silverlux) 2

3 Basiclux / Valuelux Characteristics: Light (reflection of the picture from the projector) is distributed evenly both horizontally and vertically. Gain = 1.2 Very large viewing angle (120 ). Use: When the surrounding conditions allow for a restricted gain only (e.g. standard bright rooms in our geographic area). This type of fabric is also used in big conference rooms or in auditories/lecture halls. Fabric type: Lux Silverlux / Starlux Characteristics: Entrance angle of the picture created by the projector equals the reflecting angle of the screen. Higher gain = 2.2 Large viewing angle (80 ). Use: Starlux: For projectors with weak light emission or where a higher gain is required. Silverlux: Metallising screens. Appropriate for stereoscopic 3D projections and overhead projections. 3

4 PRESENT SUCCESSFULLY A. Trapezoid distortion D. Selecting the right 4. Type of fabric Front projections typically produce fabric and screen The type of fabric is determined by a trapezoid distortion (keystoning). Selecting the right screen depends the following factors: An interesting lecture, the correct technical equipment and a friendly atmosphere make your presentation a true success. The projected picture is larger at the top of the screen than at the bottom. This distortion is caused by an inclined projection onto a straight hanging screen. Special overhead projection keystone eliminators allow for an inclined positioning of the screen to provide for an appropriate means to avoid the trapezoid distortion when using OHP. With the modern data and video projectors, the trapezoid effect can also be avoided or reduced with the keystone eliminators. B. Gain factor The gain factor describes the luminance of a fabric or a projection screen. The higher the gain, the stronger the reflection of the screen fabric. With an increasing gain factor, the viewing angle of the screen decreases. C. Angle of view The angle of view describes the angle in degree where the picture on the screen is still adequately visible. It is measured with reference to the normal of the screen center. The double angle of view (= viewing angle) thus describes the area within which an audience should be on four variables: 1. Type of screen Rear or front projection (the latter is the most common method). Mounted firmly or portable. Operated electrically or manually. 2. Screen size Depends on projection room and seating arrangement. Ideally, the following criteria are considered: the width of the screen equals 1/6 of the distance to the farthest spectator (X = 1/6 Y) the distance between floor and bottom edge of screen (A) is 90 cm, preferrably 125 cm for row seating the distance between screen and the first row (D1) is about twice the screen width (D1 = 2 X) 3. Screen format It is determined by the projection method. The format (also referred to as aspect ratio) is defined by the ratio of height to width of the screen. Depending on the projection The projection method (front or rear projection). The position of the projector. With suspended projectors (mounted to ceiling), a fabric with reflective properties should be selected. The projector. Each projector has a specific luminous efficacy (measured in ANSI lumen). If several projection devices are used (e.g. beamer and OHP), it is recommended to match the luminance (gain factor) of the fabric to the lowest ANSI lumen value. The size of the projection room. The size and the design determine the seating of the audience. The wider the seats are apart, the larger the recommended viewing angle of the screen -> Basiclux. The ambient light. The lighting conditions of the projection environment affect the presentation quality. When the lighting can be controlled, e.g. by darkening or a high illuminance of the projector, the "Basiclux" fabric can be used. seated. type, the following formats are distinguished: The rule of thumb is: keep the ambient light away from the screen; 1:1 for overhead projection the brighter the ambient light, (also referred to as square) the higher the illuminance of the 4:3 for video projection (also referred to as NTSC or video) 3:2 for slide projection 16:9 for widescreen projection projector and/or reflection of the fabric should be -> Starlux. Rear projection is substantially more insensitive to ambient light! 4

5 E. Care of screens Frequent use of a screen requires an appropriate care. All screens can be cleaned with a carefully applied weak soapsud. When not in use, the screens should be retracted to their casing to protect them against depositing dust. Avoid to touch the screen fabric with bare hands since, in the course of time, dust will stick better to the (greasy) imprints than on clean spots.
